Hi Matěj, Thanks for the reply. I work with Yasar and let me provide support to your concern.
Could you confirm if your question is related on how to authenticate in Google Ads API to avoid the error? If yes, then you may see the key things to remember below: 1. Set customer ID (without hyphen) of the manager account to login-customer-id 2. Generate Oauth2 credential / API token using user account / email address that has access to that manager account 3. Set customer ID of the client account (without hyphen), where you want to make API request, to the customer_id field. This client account should have an active link with the manager account mentioned in first step Regards, Ernie John Blanca Tacata Google Ads API Team ref:_00D1U1174p._5004Q2LmM8U:ref -- -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ Also find us on our blog: https://googleadsdeveloper.blogspot.com/ =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ You received this message because you are subscribed to the Google Groups "AdWords API and Google Ads API Forum" group.
