Create an API Definition in Tyk Classic API format.
Note that the response includes the newly created Tyk Classic API Definition containing the unique identifier for the APIs (api_id). You can provide a value for the api_id in the request body, otherwise Tyk will automatically generate a value for you.
The ID field within the Tyk Classic API Definition is a proprietary field used by Tyk to identify the API within the database and cannot be chosen or modified by the user.
