After getting token, Passing it in integration call as authorization, getting {"errorCode":"AUTHORIZATION_INVALID_TOKEN","message":"The access token provided is expired, revoked or malformed."}
Appended "Bearer " infront too but no luck. any suggestion would be a great help.
You would have to do more additional configuration for API authentication.
JWT is not DocuSign eSignature APIs Auth Token, it is a Basic token used to get Bearer auth token(for eSignature APIs) by using account-d.docusign.com/.../token(POST).
Make sure you've configured third party credentials correctly with your public and private key.
