Hi, Thank you for contacting the Google Ads API support team.
By reviewing your concern, I understand that you are trying to update the existing budget for a campaign. As per the API documentation, to replace the budget of an existing campaign, in a CampaignOperation.update, set the campaign_budget field of the Campaign object to the resource name of an existing budget (along with any other campaign fields that you might want to set). Note that this will replace the existing budget assigned to the campaign with the one specified by the campaign_budget field, since a campaign can be associated with only one budget at a time. Kindly try with the above guidelines, and if the issue still persists, provide us with the complete API logs (request and response with request-id and request header) generated at your end to assist you further. If you are using a client library and haven't enabled the logging yet, I would request you to enable logging for the specific client library that you are using. You can refer to the guides Java, .Net, PHP, Python, Ruby or Perl to enable logging at your end. For REST interface requests, you can enable logging via the curl command by using the -i flag.
