Error when Unifier pushes data to other systems

Hello everyone

     If you push the data entered in the unifier system to other systems through interface integration, how do you return the error message directly to the user when an error occurs because the data does not meet the needs of the integrated system?

     Other systems can directly return the error message and the location of the data error to the user from the front-end page, but I cannot achieve this effect from the unifier system.

     My integration method is to push data to the external system after the status of the monitoring record from the database reaches the condition, but the subsequent operation of the unifier cannot be suspended. When the external system returns an error message, the unifier record has been moved backward to proceed with the next operation. The push fails, and the user cannot know the result.
