Implementing OAuth 2.0 authentication is essential for secure and efficient integration with APIs like Codiga. This step-by-step guide walks you through the process of setting up OAuth 2.0 authentication with the Codiga API, ensuring your application can securely access and utilize Codiga's features.

Understanding OAuth 2.0 and Codiga API

OAuth 2.0 is an authorization framework that allows third-party applications to obtain limited access to user accounts on an HTTP service. Codiga API uses OAuth 2.0 to secure its endpoints, requiring developers to authenticate and authorize applications before accessing data.

Prerequisites

  • Register a developer account on Codiga
  • Create a new application in the Codiga developer console
  • Obtain your Client ID and Client Secret
  • Set up a redirect URI for your application

Step 1: Register Your Application

Log in to the Codiga developer portal and navigate to the applications section. Register a new application by providing necessary details such as application name, description, and redirect URI. After registration, note down the Client ID and Client Secret provided.

Step 2: Obtain Authorization Code

Redirect users to the Codiga authorization endpoint with your Client ID and redirect URI. The URL should look like:

https://auth.codiga.com/oauth/authorize?response_type=code&client_id=YOUR_CLIENT_ID&redirect_uri=YOUR_REDIRECT_URI&scope=read

Once the user authorizes your application, Codiga redirects back to your specified redirect URI with an authorization code.

Step 3: Exchange Authorization Code for Access Token

Send a POST request to the token endpoint with your Client ID, Client Secret, authorization code, and redirect URI. Example request:

POST https://auth.codiga.com/oauth/token

Include the following parameters in the request body:

  • grant_type=authorization_code
  • code=AUTHORIZATION_CODE_RECEIVED
  • redirect_uri=YOUR_REDIRECT_URI
  • client_id=YOUR_CLIENT_ID
  • client_secret=YOUR_CLIENT_SECRET

If successful, the response will contain an access token and a refresh token.

Step 4: Use the Access Token to Access the API

Include the access token in the Authorization header of your API requests:

Authorization: Bearer YOUR_ACCESS_TOKEN

Step 5: Refreshing the Access Token

If your access token expires, use the refresh token to obtain a new one by sending a POST request to the token endpoint:

POST https://auth.codiga.com/oauth/token

With the following parameters:

  • grant_type=refresh_token
  • refresh_token=YOUR_REFRESH_TOKEN
  • client_id=YOUR_CLIENT_ID
  • client_secret=YOUR_CLIENT_SECRET

Conclusion

Implementing OAuth 2.0 with Codiga API involves registering your application, obtaining authorization, exchanging authorization codes for access tokens, and securely managing token refreshes. Following these steps ensures your application can securely access Codiga's features while maintaining user security and privacy.
