Hi @Susi_Dman …! Yup, all you have to do is populate the Solace-Reply-To-Destination > in your request message, and you should get the response routed back to the topic or queue that you specify.
Format:
Solace-Reply-To-Destination: /(QUEUE |TOPIC)/<destination_string>
See this page for more info: Solace REST HTTP Message Encoding
Alternatively, you could explore using the REST Gateway mode (instead of REST Messaging mode), where the broker acts completely as a proxy, and will accept a variety of REST verbs (GET, PATCH, DELETE, etc.) instead of just the POST of the REST Messaging API. See here for more: REST
Hope that helps!
