Gmail API "Request had insufficient authentication scopes."

[ruben_xerket]

Hi I'm trying to send an email using gmail API.

I already have my credentials.json file and I also have a token.json file. My token.json file has the most restricted scope as you can see with the key:

"scopes": ["https://mail.google.com/"]

Nonetheless, when I try to follow https://developers.google.com/gmail/api/guides/sending#python:~:text=snippet/send%20mail/-,send_mess... to send an email, I get the following error.

```

An error occurred: <HttpError 403 when requesting https://gmail.googleapis.com/gmail/v1/users/me/messages/send?alt=json returned "Request had insufficient authentication scopes.". Details: "[{'message': 'Insufficient Permission', 'domain': 'global', 'reason': 'insufficientPermissions'}]">

```

Since you are calling the gmail API from code (I suspect), I would recommend reposting to the Workspace developer forum for APIs here.  You can also find all the gmail scopes here in the documentation. 

If you would like to try this using Low-code, you can use Application Integration with our Gmail connector (docs)...

Cheers,

Scott
