I'm using Google API Client (ruby) to access the People API and create/update my Google Contacts. I've successfully authenticated using a OAuth 2.0 flow, and have managed to use the API's methods to create new contacts.
It's been a few days that I've hit a brick wall and cannot create any new contacts. All API calls fail with the following response:
ERROR: #<Google::Apis::RateLimitError: rateLimitExceeded: Resource has been exhausted (e.g. check quota). status_code: 429
I've intentionally left 24h to go by, but as soon as I try to use the people.createContact method, I get the same error message. Here's a screenshot of the Project's metrics, showing that I've only done 20 read and just 3 write requests within one hour, and all 3 write requests fail with this error
Under no circumstances I've gone above the 90 requests per minute that the People API Quota page mentions.
I also get the same error message when I use the API Explorer interface to call the create method using curl:
Can anyone help? What is the quota that I'm maxing out?
I'd appreciate any help on this, Thanks
