API rate limiting: Customer ID based quota enforcement
- Create an API protection profile that defines the paths, servers, and responses preferably using an OpenAPI spec file.
- In the API protection profile, forAuthorization, useOAuth 2.0.
- On the Rate Limiting tab of the API protection profile, use the predefined identity key calledClientAppIDin two rate limiting configurations that use different request quotas and spike arrest values for each airline.
- On the Access Control tab, clickEditto see the visual representation of the per-request policy that was created.
- In the visual policy editor, edit the policy as needed for rate limiting each application. Create API Rate Limiting agents for each application and in each agent, select the appropriate configuration and response for that airline.
How it works
- Access Policy Manager receives an API request with an authorization header containing a JWT access token.
- The access token is extracted from the authorization header.
- For all API requests, the OAuth Scope agent in the subroutine validates the access token.
- If OAuth validation fails, the system returns an appropriate response for that API request.
- On successful validation of the JWT access token, the policy classifies the request based on the value ofClientAppIdand sends it to the appropriate branch.
- By assigning different Rate Limiting configurations in the two API Rate Limiting agents, the policy enforces different rate limiting quotas for each airline.
- If the number of requests exceeds the quota, the system returns a response to the sender of the API request, and logs an error message.
