Hi,
I understood that I can still use stored refresh tokens when migrating from
Google Adwords to Google Ads as
per https://developers.google.com/google-ads/api/docs/migration/carryover :
"The requirements for authentication remain the same. The Google Ads API
uses OAuth2 for authentication, which requires an access token at the time
of the request. You can re-use your existing refresh token, client id, and
client secret that were used for the AdWords API without any adjustments."
But we are seeing exceptions like this:
MethodName:
google.ads.googleads.v6.services.CustomerService/ListAccessibleCustomers
Endpoint: googleads.googleapis.com:443
Headers: {developer-token=REDACTED, x-goog-api-client=gl-java/11.0.11
gapic/ gax/1.60.1 grpc/1.34.1}
Body:
Response
--------

Body: null
Failure message: null

metadata, cause=com.google.api.client.http.HttpResponseException: 400 Bad

}.
Once re-authenticated, (obtained new refresh token, it starts to work
without above exception being thrown.
