Describe the problem/error/question
I am interfacing with an API that will be called periodically with a cron node. The Oauth2 token expires after 30 minutes and therefore I am relying on the OAuth2 API to automatically refresh my token.
The API uses a different refresh URL to the one used to retrieve the token from. There’s no way to specify a different refresh URL (auth/refresh in my case) in the OAuth2 credential though.
It tries to refresh the token as expected but the token URL doesn’t accept the refresh_token and throws this error:
{"status":"rejected","reason":{"body":{"error":"unsupported_grant_type","error_description":"The authorization grant type is not supported by the authorization server.","hint":"Check that all required parameters have been provided","message":"The authorization grant type is not supported by the authorization server."},"code":"EAUTH"}}
Is there a way to work around this without modifying or adding custom logic to the HTTP node to use a different refresh URL?
