Hello,
Thank you for reaching out to Google Ads API Forum.
Upon checking the documentation (https://developers.google.com/google-ads/api/rest/reference/rest/v13/customers.campaignConversionGoals/mutate), it appears that only “update” operation is possible on a campaign conversion goal.
As per this guide (https://developers.google.com/google-ads/api/rest/reference/rest/v13/ResponseContentType), responseContentType determines the returned format or resource name of the mutated resource, whether the mutable resource or just the resource name should be returned as a response.
Since the update operation in customers.campaignConversionGoals.mutate is expected to have a valid resource name, this is probably why responseContentType is not available as a field in the request body. Furthermore, there is no way to auto-detect if this field is supported in particular mutate operation. With this, I would suggest checking our documentation (https://developers.google.com/google-ads/api/rest/reference/rest) for reference if this field is supported.
