[Proto definition ![GitHub](https://developers.google.com/site-assets/logo-github.svg)](https://github.com/googleapis/googleapis/blob/master/google/ads/googleads/v24/services/conversion_upload_service.proto)

| Fields ||
|---|---|
| ## `conversions[]` | `CallConversion` Required. The conversions that are being uploaded. |
| ## `customer_id` | `string` Required. The ID of the customer performing the upload. |
| ## `partial_failure` | `bool` Required. Must be set to `true`. Enables partial failure mode so that valid conversions are processed and any invalid conversions return individual errors in `partial_failure_error`. Setting this field to `false` is not supported and causes the entire request to fail. See [Best practices for partial failures](https://developers.google.com/google-ads/api/docs/best-practices/partial-failures.md.txt). |
| ## `validate_only` | `bool` If true, the request is validated but not executed. Only errors are returned, not results. |
