Hello Andrew, If you look at the log for your response, you will see that in the update_mask field the amount_micros is missing, which is the reason why the amount is not being changed.
I am not a Python expert, but I think the reason for this issue is in the line client.copy_from(campaign_budget_operation.update_mask, protobuf_helpers.field_mask(None, campaign._pb)) Which is passing a campaign object to protobuf_helpers.field_mask. Instead, I think it should be, in your code, client.copy_from(campaign_budget_operation.update_mask, protobuf_helpers.field_mask(None, campaign_budget_resource_name._pb)) This should create the right field mask for the API request to indicate that the amount_micros field is being mutated, which in turn should result in the value being actually updated by your API request. Hope this helps, Mattia Tommasone Google Ads API Team ref:_00D1U1174p._5004Q2bxZGB: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.
