Mirth Connect HTTP Listener Mapping Response ACK message

We are trying to merge two Mirth servers. One server (let's call it Server 1) is keeping all records and another server (Server 2) is getting HL7 message from the first one and writes messages to the database.

Everything was perfect so far. But Server 1, after sending each HL7 message, waits for ACK to consider this transaction as completed and to send another message from the list.

The success status coming from the Server 2 (which writes to the database) contains MySQL response such as "Success: Database write success. 1 rows updated.". This is not what Server 1 is expecting.

Therefore, the Server 1 considers this ACK as invalid, produces an error "Message Read Error - Will Retry" and keeps trying to send the same message again, causing Server 2 to duplicate messages in the database.

We are using Mirth Connect HTTP listener and we could not find any solution to send ACK msg to our first server the same screen HTTP listener.

Is there any way to do this? Any Suggestion?

Really need help.

The problem is you are not setting the response from server 2 correctly, so it just returns what the destination has. You can create an ACK by code on the destination transformer:

var ackMessage = ACKGenerator.generateAckResponse(connectorMessage.getRawData(), "AA", "Message Successfully Received");
responseMap.put("ackresp", ResponseFactory.getSentResponse(ackMessage));

And on your source connector select "ackresp" as response. Your server 1 will receive that ACK instead of the log of the database write.
