Bubble.io API Connector Authentication: A Practical Guide

When integrating APIs into your Bubble.io projects, understanding the various authentication methods and their components is key to secure and efficient application development. Here's a straightforward look at each authentication type supported by Bubble.io’s API connector and the specific inputs required for each.

1. None or Self-Handled

• Purpose: For APIs that do not require authentication or when you prefer to handle authentication through your own custom method.
• Inputs Required: None.

2. Private Key in URL

• Purpose: Includes a private key directly in the API request URL. This method should be used carefully due to potential exposure of the key.
• Inputs:
  • Key Name: The name of the key parameter in the URL.
  • Private Key: The key value.
  • Development Key Value: A key used specifically in development environments.

3. Private Key in Header

• Purpose: A safer approach than using the URL, this method places the key in the HTTP request headers.
• Inputs:
  • Key Name: The name of the header where the key is included.
  • Private Key: The key value used for authentication.

4. HTTP Basic Auth

• Purpose: Uses a username and password for authentication, encoded and sent in the header of HTTP requests.
• Inputs:
  • Username: The username or account identifier.
  • Password: The corresponding password.

5. OAuth2 Password Flow

• Purpose: Directly handles user credentials to securely obtain an access token, suitable for applications where users can trust the application with their login information.
• Inputs:
  • Username: The user's login username.
  • Password: The user's login password.
  • Token Endpoint POST: The endpoint URL where credentials are submitted to retrieve an access token.

6. OAuth2 User Agent Flow

• Purpose: Ideal for client-side applications where authentication is handled by the user's browser, without exposing credentials to the server.
• Inputs:
  • APP ID and APP Secret: The application's credentials registered with the OAuth provider.
  • DEV. APP ID and DEV. SECRET: Development credentials for testing.
  • SCOPE: The scope of access requested.
  • Authentication goes in the header: Indicates whether authentication info is to be included in the header.
  • Token is returned as a querystring: Specifies how the token is returned.
  • Token Name: The name of the token parameter.
  • Add access_type=offline (Google APIs): For requesting refresh tokens.
  • Use a generic redirect URL: The redirect URL used after authentication.
  • Login dialog redirect: URL for the login dialog.
  • Access token endpoint: URL to retrieve the access token.
  • User profile endpoint: URL to retrieve user profile information.
  • User ID key path, User email key path: JSON path to extract user ID and email from the profile data.

7. OAuth2 Custom Token

• Purpose: Allows for a custom implementation of OAuth2 for APIs with unique requirements.
• Inputs:
  • Token Endpoint POST: The endpoint for the token request.
  • Body: Specific data sent in the POST request, often in JSON format.

8. JSON Web Token (JWT)

• Purpose: Provides a secure way to transmit information as a JSON object, which can be verified and trusted because it is digitally signed.
• Inputs:
  • Scope: Permissions associated with the JWT.
  • ISS (Issuer Account Email): Email of the token issuer.
  • Access token endpoint: URL to retrieve the access token.
  • Private Key: Used to sign the JWT.

9. Client-Side SSL Certificate

• Purpose: Utilizes SSL certificates for client authentication, ensuring secure, mutual authentication between the client and server.
• Inputs:
  • Certificate file content: The content of the certificate file.
  • Key file content: The private key associated with the certificate.
