Hmm, I don’t know enough to give you a confident answer yet. The extracts provided do not contain specific information on how to integrate the provided code into a check function for a custom Python destination in Airbyte. However, I can guide you on how to create a custom OAuth for your connector based on the information from the forum post. Here’s an example: python from requests.auth import AuthBase from requests_oauthlib import OAuth1 class MyAuth(AuthBase): def __init__(self, oauth): self.oauth = oauth def __call__(self, r): r.headers["Authorization"] = self.oauth return r oauth = OAuth1( client_key=config["consumer_key"], client_secret=config["consumer_secret"], resource_owner_key=config["access_token"], resource_owner_secret=config["token_secret"], ) return [MyStream(authenticator=MyAuth(oauth))] For more detailed guidance, you may want to refer to the Airbyte documentation or ask your question on the #help-connector-development channel on Slack.
