@leandro-menagonzalez So it sounds like you seeing the consents be granted in the Google process, which should make it available in the reconcile lambda, but you are not seeing the value in the reconcile lambda?

There are two options I'd explore:
Using the OIDC identity provider, which gives you more flexibility and possibly more information. In particular, you get both the access and id token: https://fusionauth.io/docs/v1/tech/lambdas/openid-connect-response-reconcile
Using Lambda HTTP Connect (a paid feature) to make a call to the google APIs to request additional information from within your lambda. You can learn more about that here: https://fusionauth.io/docs/v1/tech/lambdas/#using-lambda-http-connect
Hope that helps.
