'Failed to retrieve auth metadata with error: invalid_grant' - Exception occurred in retry method that was not classified as transient'

[Sam Pascoe]

 I'm getting the error:

 code: 16,

  details: 'Failed to retrieve auth metadata with error: invalid_grant',
  metadata: Metadata { internalRepr: Map(0) {}, options: {} },

  note: 'Exception occurred in retry method that was not classified as transient'

re-entering a new refresh token seems to be the only fix. It happens once a week.

Hi Sam,

Thank you for posting your concern. Allow me to provide support.

I can see that you encountered an invalid_grant error, it occurs when the refresh token has been expired or revoked. The common cause of this error is when a Google Cloud Platform project with an OAuth consent screen configured for an external user type and a publishing status of "Testing" is issued a refresh token expiring in 7 days. Your Google project's publishing status is "Testing", so the refresh token expires every 7 days and receives an “invalid_grant” error. Go to the Google API Console and navigate to the OAuth consent screen. Then change the publishing status to “In production” following these instructions to avoid the refresh token expiring in 7 days.

Let me know if you have further questions.

I am using this site: https://refresh-token-helper.opteo.com/ to generate my refresh token. Should I be using a different method?

I followed the link above but there is no mention of refresh tokens anywhere on the page. 

I already have a client ID and client secret

Hi Sam,

Thank you for your reply. I'm also a member of the Google Ads API support team. Upon checking the link provided, the refresh tokens information is in the OAuth Playground section. With this, you may check this document, directly to the information about generating tokens. Let me know if you have further questions.
