Getting API Usage Plan in header

Question

Hello,

I have a use case to validate the Usage Plan to offer certain functionality. Could you please advise what/how I can do so every request adds Usage Plan details in the request header to my backend servers?

Thank you.

Answer

There is no context variable that contains the usage plan, so you can't directly achieve what you want. If you use a Lambda authorizer, it can calculate the usage plan and return it in a context variable, which later can be used by a mapping template in an HTTP header.

Another option is to include the usage plan name in the API key ID, e.g., `plan1-key1`, `plan2-key3`, etc. and use `$context.identity.apiKeyId` in the mapping template. The backend can then retrieve the information from there.

Answer

Thank you Uri for your help. The second suggestion might work. Let me check with my developer.
