I am trying to retrieve information via Google Analytics Management API. In particular the account IDs, all available profiles etc. so I can build a loop that fetches information from all available accounts.
I’d like to use the Google API Auth-Node (O-Auth or via API) which can save the authentification in a local file. Unfortunately the format is not documented / comprehensible.
When trying to build the query my own, based on the workflow attached I found in another forum post, I fail as well.
Sadly it is not possible to use the authentication that is stored in the local file outside of the Google Authentication node. You could use it when you use the Java snippet node and Google libraries, but that might be out of scope.
The workflow that you attached however should provide you with the necessary access/refresh token to issue your queries. I guess you found it here. If you follow the step by step guide you should end up with valid tokens which you can use in node #167 (Create Request With Access Token):
