Help Needed: Integrating Trello API with CustomGPT on OpenAI’s ChatGPT - API Key and Token Issue

Context:

We are integrating Trello’s API with CustomGPT on OpenAI’s ChatGPT to fetch boards and create cards. We have an API key and an authentication token, but the OpenAPI 3.0 spec seems to support only one key.

Steps Taken:

  1. API Key and Token: Successfully obtained from Trello.
  2. OpenAPI Specification Attempts:
    • Tried using Authorization header for Base64 encoded key:token.
    • Faced issues with OpenAPI spec ignoring Authorization header.
    • Tried using key and token as query parameters but encountered authentication errors.

OpenAPI Specification (Latest Attempt):

openapi: 3.0.0

Issues Encountered:

  • OpenAPI spec ignored the Authorization header.
  • Authentication errors when using key and token as query parameters.

Questions:

  1. How can we correctly integrate both the API key and token in the OpenAPI spec for Trello API?
  2. Is there a recommended approach to authenticate Trello API requests in the CustomGPT environment?

Any guidance on this would be highly appreciated!
