Before your application can access merchant data or act on the merchant's behalf, it must be authenticated. To make this process as easy as possible, provides the industry-standard OAuth protocol for granting access. Overview The following diagram illustrates the process of receiving merchant permission, retrieving an authorization code, redirecting the merchant, and retrieving an access token. 1. The merchant visits your application, enters form information, and clicks a link or button to continue the process. 2. Your application redirects the merchant to 3. The merchant grants or denies to your application the permissions that you will provide when you register your application with 4. returns an authorization code, contained in a redirect URL. This redirects the merchant back to your application. 5. Your application calls and exchanges the authorization code for a token that can be used for authenticating transactions with as well as a refresh token that can used for additional calls. Endpoint URLs Sandbox Production Registering Your Application Before you can use OAuth credentials to connect to on behalf of your merchant, you must register your application with us. You can register your application in the Partner Interface. There are separate URLs for production and sandbox. For sandbox credentials, contact developer_feedback Production Partner Interface Sandbox Partner Interface To register your application Step 1. Log into the Partner Interface see the production and sandbox URLs above, navigate to Partner Account, and click the Integrate tab. Step 2. Click Add Application. Enter the following information Text Field Information Application NameName of the application for which you are requesting OAuth of the URLURL used to redirect the merchant to so that they can log in with their credentials and authorize your application to perform certain actions on their behalf. See our OAuth API documentation page for more the permissions to give the application for the listed APIs, or for all listed APIs. Step 3. Click Submit. Your application is registered and the Client ID and Client Secret are shown. Store them securely. You will need them to redirect the merchant, which is explained in the next section. Click Done to return to the previous screen. You can view your application in the Integrations page. Note that a Solution ID in shown in the right column of the Applications list. That Solution ID is now linked to your Client ID and will be audited automatically. Redirecting the Merchant When the merchant arrives at your site, you must redirect them to so that they can log in with their credentials and authorize your application to perform certain actions on their behalf. Add a link to your site that contains the redirect URL that you supplied to during registration, encoded with the following parameters as a query string Parameter Name Required Notes client_idYesThis is the client ID appointed to your application by during is the page that the merchant is redirected back to after granting you permissions. This must exactly match the redirect URL that you supplied during the level of access that the application is requesting. Read-only permissions are for solutions that only need to read data and not create or update information on the merchant's and write permissions allow all API calls for any enabled services, including generating transactions, ARB subscriptions, and CIM value is echoed back in the response to protect against malicious interception, for example a CSRF value must be oauth. When the user initiates the redirect, the merchant is redirected to and if they are not already logged in, they will be prompted to do so. If the merchant's credentials are expired, they will be prompted to reset it, after which they must click the redirect link again. The interface page opens, stating the partner's name along with the permissions requested. The merchant is prompted to either Allow or Deny the request for permissions. Merchants giving permissions to your application must log into their Merchant Interface as an Account Owner or Account Administrator. They must also generate an API Login ID and Transaction Key, if they haven't already. When the merchant clicks Approve, redirects them back to the URL that you defined in your redirect_uri parameter. Attached to the redirect_uri will be two important URL arguments that you need to read from the request Response Parameter Name Required Notes codeYesThe code is the value that you will exchange with for an access token in the next step of the authentication process. For security reasons, the authorization code has a ten minute lifespan and must be used before it expires; otherwise you must repeat all of the previous steps to request another. stateYesA value used to test for possible CSRF attacks. This value is echoed back to you in the response from If the state values do not match, you could be the victim of a CSRF attack and you should throw an HTTP 401 error code in response. Error Responses Error Code Description invalid_scopeThe requested scope is invalid, unknown, or requested client_id is invalid, unknown, or request is missing a required parameter, includes an invalid parameter value, includes a parameter more than once, or is otherwise malformed. unauthorized_clientThe client is not authorized to request an authorization code using this requested redirectUri is invalid, unknown, or requested client_id is not found in the requested client_id is registered with invalid client type only confidential clients are supported. Retrieving the Access Token Use the authorization code that you obtained in step 2 to retrieve an access token, which expires after one hour, and a refresh token, which expires after one year, from our /token REST endpoint. Sample Token Request Below is an example of a token request. While a header is not required, we recommend including the header v-c-client-correlation-id with a unique value, for every request to /token. Token Request Parameters Parameter Name Values Description grant_typeauthorization_codeRequired. This determines what type of flow the Authorization Server will use to acquire user authorization. codeThe authorization code received from the authorization The value passed in this parameter must exactly match the value supplied by the OAuth server during the authorization step. client_idThe client ID obtained during client Indicates the client that is making the request. client_secretThe client secret value obtained during client Provides additional security. Sample Token Response Error Responses Error Code Description access_deniedThe resource owner or authorization server denied the authorization server encountered an unexpected condition that prevented it from fulfilling the request. This error code is needed because a 500 Internal Server Error HTTP status code cannot be returned to the client by an HTTP redirect. Important If you submit an expired token, you will receive a 401 error, as shown below. Submitting API Requests Use the access token to authenticate transactions. For requests to the API, the access token is included in the merchantAuthentication block as shown in the following example In requests to the REST API, the access token is sent in an HTTP Authorization header with the Bearer type, as shown in the following example Authorization Bearer eyJraWQiOiIyNmRjfjVkZTdlMmYwYTI0ODg0MjU1YjIwZWJjMGY0MSIsImFs Error Responses The following error is returned when the access token is invalid. For more information about specific error responses when using the API, see our Response Code Tool. Refreshing the Access Token To refresh the token, send a POST to the /token endpoint that contains the following parameters Parameter Values Description client_idThe client ID obtained during client Indicates the client that is making the client secret value obtained during client Provides additional security. grant_typerefresh_tokenRequired. This determines what type of token is value of the refresh The value passed in this parameter must exactly match the refresh token value provided during the creation of the access token. Sample Token-Refresh Request Below is an example of a token refresh request. While a header is not required, we recommend including the header v-c-client-correlation-id with a unique value, for every request to /token. Sample Token-Refresh Response Error Responses HTTP Status Code Error Error Description Notes 400invalid_requestThe request is missing a required client .Returned if the client ID does not exist in our status is status is set to expired in the grant if the client requests a grant type that is not supported by this the username or merchant is not valid, the account is disabled or locked, or the password is invalid or has to create server error. Revoking Permissions If the merchant revokes a solution's permissions in the Merchant Interface, they will also revoke the refresh token immediately. Any previously issued access token will be valid till they expire. No new access token can be generated. Boarding Integration The OAuth boarding flows enable you to board a merchant and then do OAuth delegation for the newly boarded merchant during the same flow. Two boarding flows are supported Landing page flowMINT login flow Landing Page Flow By default, two pricing options are shown Payment gatewayPayment gateway with merchant account To show only one pricing option, add a profileTypeID parameter to the URL and use a value of 1 to show pricing for payment gateway only, or 2 to show pricing for both merchant account and payment gateway. Example URL with profileTypeID NOTE To use the testing environment, replace with After the merchant accepts the pricing option, they are redirected to the OAuth page. Whether they accept or reject the OAuth delegation options, they are then redirected back to the partner site. MINT Login Page Flow The following sample URL shows how to redirect the customer to the MINT login page. NOTE To use the testing environment, replace with When the merchant clicks "Sign up now" they are shown pricing flows that depend on how you submitted profileTypeId. Add a profileTypeID parameter to the URL and use a value of 1 to show pricing for payment gateway only, or 2 to show pricing for both merchant account and payment gateway. After the merchant accepts the pricing option, they are redirected to the OAuth page. Whether they accept or reject the OAuth delegation options, they are then redirected back to the partner site. Setting the Merchant Account to Live Mode When a merchant account is first created, it is set to Test mode by default. Before live transactions can be processed, the account must be set to live mode. You can do this by submitting updateMerchantDetailsRequest with isTestMode as shown below. Please note that while this call can usually be processed within moments of an account being created, certain circumstances may cause up to a 15 minute delay before it can be attempted. Example isTestMode Request

Created March 13, 2017 Category Troubleshooting Comments 31 When you schedule a posts on Pilot Poster, in some rare cases, the scheduled posts might hit a hard rock on the way due to some reasons, and among the common reasons for a scheduled post to stop running is the Invalid Access Token error. How to Detect this Error Pilot Poster comes with a Logging feature that stores all of the errors encountered during a scheduled post. And to locate the error log, you need to Navigate to Posts > Scheduled Posts > And Click the Folder Icon at the right-hand side of the displayed table. Fix Invalid Access Token Error In the Log page, you will see the reason why your scheduled posts stopped running and if the error message seen is Invalid Access Token as shown in the image above, then read below to see how to fix; How to Fix Invalid Access Token Error The invalid access token error simply means the token for the selected app used for posting is expired and needs to be re-authenticated. And to fix, all you need to do is Re-authenticate the current app used for posting. To Re-authenticate, Goto Settings > Facebook Apps > Deauthenticate the App. And then click the Authenticate button again. When you click the Authenticate button again, you do NOT need to go through all of the procedures as you would when Authenticating for the first time. Rather, all you need to click is the Get App Authenticate Link As shown in the image below. re-authenticate-app Copy the displayed access token from the next window that displays and then paste in the Access Token Box. Click the Test Access Token to ensure the copied token is valid, then click the Set Access Token Button. You have successfully re-authenticate your app. Now is time for you to resume the paused schedule or schedule a new post using your authenticated app. Was this article helpful?

Most of the machine learning models and deep learning models do prediction through APIs must be secured in such a way that no one can use it without your permission. There are many ways to do API authentication but the popular and common one is JWT authentication. In this entire intuition, you will know how to secure your API using Flask and MongoDB. I am assuming that you already have knowledge of Flask and MongoDB. Here is the only implementation part. You will learn the following thingsHow to register the Users?Login Flask route for AuthenticationAccessing the API route with Generated by Steps to Secure your APIStep 1 Import the necessary pymongo from flask import Flask, jsonify, request from flask_jwt_extended import JWTManager, jwt_required, create_access_token from pymongo import MongoClientPymongo is the official MongoDB Database Python Package. Flask is the Python Web Framework and flask_jwt is the JWT plugin for the Flask 2 Connect to the MongoDB Database ServerBefore knowing further keep in mind that MongoDB is schemaless Database Management System. It is a No SQL database and it differs from other SQL databases. You can do all SQL operations like Create, Read, Update and Delete without creating any Class Model in Python. Use the following code to connect create db and collection for the MongoDB. Making a Connection with MongoClient client = MongoClient"mongodb//localhost27018/" database db = client["app_database"] collection user = db["User"]Here, First of all, you will create a client for connection using the MongoClient method and pass the database URL. I am using the database locally so it is ” mongodb//localhost27017/“. After that create a database named “app_database“,using client[“app_database”] and then collection “User” using db[“User”].Step 3 Create a Flask app and Configure itAfter making a connection with MongoDB the next step is to create a Flask App and do some configuration on it. Use the Following Codeapp = Flask__name__ jwt = JWTManagerapp JWT Config = "this-is-secret-key" change itAs you can see in the above code. First I have created an app and pass it into the JWTManagerapp method to secure the entire Flask Application and also config the 4 Design your Flask API routesNow You will design API routes for registering, log in. Use the following code. methods=["POST"] def register email = test = test = email} if test return jsonifymessage="User Already Exist", 409 else first_name = last_name = password = user_info = dictfirst_name=first_name, last_name=last_name, email=email, password=password return jsonifymessage="User added sucessfully", 201In the registered route first I am checking that the email is in the database or not and if it is not then Insert the form response to the Database. To find an email in the database You will use the find_one method and for adding the insert_one method. After registration, it will return the JSON response with the message User added successfully otherwise returns User Already Route methods=["POST"] def login if email = password = else email = password = test = email,"password"password} if test access_token = create_access_tokenidentity=email return jsonifymessage="Login Succeeded!", access_token=access_token, 201 else return jsonifymessage="Bad Email or Password", 401For the login route, I have created the condition for checking the JSON and form response. Thus it works for both the requests from Json or also I am using the find_one method for checking username and password. If it is ok then I give the user an Access Token that will be valid for some time to access the Other routes that require 5 Secure the RouteLet’s create a route and test and secure it. First, you will create it and then add a decorator below the routeabove the function definition. Use the following code. jwt_required def dasboard return jsonifymessage="Welcome! to the Data Science Learner"Full Codeimport pymongo from flask import Flask, jsonify, request from flask_jwt_extended import JWTManager, jwt_required, create_access_token from pymongo import MongoClient Making a Connection with MongoClient client = MongoClient"mongodb//localhost27018/" database db = client["app_database"] collection user = db["User"] app = Flask__name__ jwt = JWTManagerapp JWT Config = "this-is-secret-key" jwt_required def dasboard return jsonifymessage="Welcome! to the Data Science Learner" methods=["POST"] def register email = test = test = email} if test return jsonifymessage="User Already Exist", 409 else first_name = last_name = password = user_info = dictfirst_name=first_name, last_name=last_name, email=email, password=password return jsonifymessage="User added sucessfully", 201 methods=["POST"] def login if email = password = else email = password = test = email, "password" password} if test access_token = create_access_tokenidentity=email return jsonifymessage="Login Succeeded!", access_token=access_token, 201 else return jsonifymessage="Bad Email or Password", 401 if __name__ == '__main__' debug=TrueAll testsRegistrationWhen you press the send button again you will get the error Details inside the MongoDB TestingUse the token key to get into the dashboard route defined Login if you try to access the dashboard URL. Then you will get the following error LoginConclusionFlask is a micro web framework for Python. In addition, you can use it to secure your API for machine learning. This entire intuition covers a basic but effective authentication using username and password. Here you can see that I am storing the password as a simple text. But you can store it as a hashed version in the database. But you have to create an algorithm depending upon your you have understood all the concepts mentioned here. If you have any query about it then you can contact us or message us at the official Data Science Learner ScenariosPython Connect to MongoDB with username and passwordYou can also create a document that contains the username and password for the user. It will allow you to the first login to the user with a username and password and the JWT API keys for login sessions. Therefore for a particular time, the user will be logged in, and when the session expires the user will log out and he/she have to login again to our listSubscribe to our mailing list and get interesting stuff and updates to your email respect your privacy and take protecting it seriouslyThank you for signup.

Tokenbased authentication. To make a web API call from a client such as a mobile application, you must supply an access token on the call. The token acts like an electronic key that lets you access the API. Magento issues the following types of access tokens: Token type. Description. Default lifetime.Docs Appwrite uses conventional HTTP response codes to indicate the success or failure of an API request. In general Codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided a required parameter was omitted, invalid input, etc.. Codes in the 5xx range indicate an error with the Appwrite server, but these are rare. Code Text Description 200 OK Success! 201 Created The requested resource has been created successfully. 204 No Content The server has successfully fulfilled the request and that there is no additional content to send in the response payload body. This status will usually return on successful delete operations. 301 Moved Permanently The URL of the requested resource has been changed permanently. The new URL is given in the response. 304 Not Modified There was no new data to return. 400 Bad Request The request was invalid or cannot be otherwise served. An accompanying error message will explain further. Requests with wrong or invalid input will yield this response. 401 Unauthorized Missing or incorrect authentication credentials can happen when the API key or user permission is not sufficient. 403 Forbidden The request is understood, but it has been refused, or access is not allowed. An accompanying error message will explain why. Make sure to register your app in your project's dashboard platform list. 404 Not Found The URI requested is invalid or the resource requested, such as a user, does not exist. 409 Conflict This response is sent when a request conflicts with the current state of the server. This status code will usually appear when you're trying to create an already existing resource. 416 Invalid Range Invalid value in the range or content-range headers. Usually returned while uploading or downloading files using range header but the provided range value is not valid. 429 Too Many Requests Returned in when a request cannot be served due to the application’s rate limit having been exhausted for the resource. See Rate Limits 500 Internal Server Error Something is broken. Contact our team, or raise a GitHub issue. 501 Not Implemented The feature is not implemented. Usually returned when the project owner has disabled an auth method or an entire service. 503 Service Unavailable The Appwrite servers are up but overloaded with requests. Try again later. 504 Gateway timeout The Appwrite servers are up, but the request couldn’t be serviced due to some failure within the stack. Try again later. Error MessagesWhen the Appwrite APIs return error messages, it does so in JSON format. For example, an error might look like this { "message" "Invalid id Parameter must be a valid number", "type" "argument_invalid", "code" 400 } Error Types Appwrite also passes convenient error types in addition to the HTTP response codes to help you get more fine grained control over what went wrong and allowing you to display relevant error messages in your applications. Error types are are convenient to identify the type of error that occurred. For eg A 400 HTTP response code could indicate a Bad Request due to a variety of reasons and error types can help you pinpoint the exact 400 error. Appwrite currently supports the following error types Code Type Description 400 general_mock General errors thrown by the mock controller used for testing. 400 general_argument_invalid The request contains one or more invalid arguments.

Tosend a message, we need to create a messaging token that is unique to each device . Once acquired, it then needs to be saved to a datastore (e.g. an external database). When the time comes to send a message, the token is read from the datastore and a data payload is sent via FCM to the specific device with the token assigned.To authenticate to and access Databricks REST APIs, you can use Databricks personal access tokens or passwords. Databricks strongly recommends that you use tokens. Important Tokens replace passwords in an authentication flow and should be protected like passwords. To protect tokens, Databricks recommends that you store tokens in Secret management and retrieve tokens in notebooks using the Secrets utility A local key store and use the Python keyring package to retrieve tokens at runtime. Note As a security best practice, when authenticating with automated tools, systems, scripts, and apps, Databricks recommends you use access tokens belonging to service principals instead of workspace users. For more information, see Service principals for Databricks automation. Requirements Token-based authentication is enabled by default for all Databricks accounts launched after January 2018. If token-based authentication is disabled, your administrator must enable it before you can perform the tasks described in Manage personal access tokens. Generate a personal access token This section describes how to generate a personal access token in the Databricks UI. You can also generate and revoke tokens using the Token API The number of personal access tokens per user is limited to 600 per workspace. Click Settings in the lower left corner of your Databricks workspace. Click User Settings. Go to the Access Tokens tab. Click the Generate New Token button. Optionally enter a description comment and expiration period. Click the Generate button. Copy the generated token and store in a secure location. Revoke a personal access token This section describes how to revoke personal access tokens using the Databricks UI. You can also generate and revoke access tokens using the Token API Click Settings in the lower left corner of your Databricks workspace. Click User Settings. Go to the Access Tokens tab. Click x for the token you want to revoke. On the Revoke Token dialog, click the Revoke Token button. Use a personal access token to access the Databricks REST API You can store a personal access token in a .netrc file and use it in curl or pass it to the Authorization Bearer header. Store tokens in a .netrc file and use them in curl Create a .netrc file with machine, login, and password properties machine login token password where is the instance ID portion of the workspace URL for your Databricks deployment. For example, if the workspace URL is then is token is the literal string token. is the value of your token, for example dapi1234567890ab1cde2f3ab456c7d89efa. The result looks like this machine login token password dapi1234567890ab1cde2f3ab456c7d89efa For multiple machine/token entries, add one line per entry, with the machine, login and password properties for each machine/token matching pair on the same line. The result looks like this machine login token password dapi1234567890ab1cde2f3ab456c7d89efa machine login token password dapi2345678901cd2efa3b4cd567e8f90abc machine login token password dapi3456789012de3fab4c5de678f9a01bcd Important You can optionally set login to your Databricks username and password to your Databricks password. However, Databricks recommends that you use a personal access token to authenticate to an API endpoint. If you choose to use a username and password, do not use -u to pass your credentials as follows **Do not** do this. curl -u -X GET https///api/ This example invokes the .netrc file by using -netrc you can also use -n in the curl command.
