Can I authenticate using jwt-gmail api?
google developer : 'https://github.com/googleapis/googleapis/tree/master/google'
It says that only the api at this address can use this method.
But I can not find the gmail api here.
Can the gmail api only use the access token method using oauth 2.0?
I do not know what you mean by jwt-gmail api. That being said.
I think your looking at the wrong library try google-apis-nodejs-clinet.
Gmail api facts normal user gmail accounts can only be accessed using Oauth2 if its a gsuite account then you can use domain wide deligation and user a service account
