Hi Team I am trying to develop an application where we connect to a Queue ( which is subscribing to multiple topics) and read message synchronously and make sure the next message is consumed only after current message is acknowledged. I tried reading resources provided by solace documentation and found snippet available only to subscribe to a topic but not Queue. I need an reference or simple code snippet to understand and develop the same. Kindly help. Any sought of help is appreciated ? ---

Hey there @Pavithra ! I’ll take a stab at this and mention there are multiple approaches for the desired behaviour you are attempting to achieve: - You can set the `MAX_DELIVERED_UNACKNOWLEDGED_MSGS_PER_FLOW` on the queue to set the maximum number of messages delivered but not acknowledged per flow for the Queue. In your case you want this set to 1 - Set the `FLOW_WINDOW_SIZE` to 1 when binding to the queue from your application. This controls how many messages can leave the broker (i.e. queue) to the API/App at once. It is important to note that the `MAX_DELIVERED_UNACKNOWLEDGED_MSGS_PER_FLOW` should be greater than or equal to `FLOW_WINDOW_SIZE` There are a couple of community posts that would help with this if you want to dig further, but thats a starting point! ---

Hi @Tamimi Thanks for your prompt response ?. But I was seeking for code snippet example (without using listener). Anyways I tried creating connection, session, consumer and applied recive() method to receive messages without opening any listener and it worked. Thanks for your support as always. ---
