Architecture

Catalyst API Gateway’s architecture is shown below:

Catalyst API Gateway performs tasks in the following sequence:

1. Reading the request method and URL of the client request
2. Searching for an API that you have configured for the particular request method and URL
3. Initiating the API, if available, or denying the request if the API is unavailable
4. Checking the throttling configuration and verifying if the request is within the defined rate limits, if applicable
5. Checking the authentication configuration and initiating a handler to verify the credentials, if applicable
6. Enabling the API to redirect the client to the configured target URL, if all validations are passed
