Google Ads API FieldMaskError: FIELD_MASK_MISSING
- 1
Build the resource with its resource_name and only the fields you intend to update.
- 2
Generate an update mask from the populated fields or provide the documented field paths explicitly.
- 3
Run validate_only first, then send the mutation after the mask matches the payload.
WHAT THE ERROR MEANS
The update operation contains a resource but no valid update_mask.
FIELD_MASK_MISSING occurs when an update operation does not specify which resource fields should change.
