One question I can't seem to find any docs about. I have made a PHP API that uses the Dynamic Security Plugin.

Is there any way I can map the pub with the response in the sub topic? As of now it returns in the response topic something like this:

"{"responses":[{"command":"createRole","error":"Role already exists"}]}"

But if I have multiple requests, it would be nice to have a way to map them together. For instance sending a ID on the publish that is returned in the corresponding response.

Any ideas?

Using the Request-Response Pattern introduced in MQTT 5, you can provide response topic on each publish message. So that you can map the corresponding message topic to their response topics.
