Extracting message ID on solace pub sub broker in golang API

lukamacan

 Hello everyone, currently I am researching Solace GoLang Api and I have few questions. Can you please help me because I cannot find the answer.

1. How can I extract message ID or is there any unique ID that can be extracted from Inbound message and used for distinguishing messaged published to message broker
2. I would also like to know how to set sequence number on publisher side. Right now I am using GetSequenceNumber() method and can't get anything but 0 because it is not set on publisher side.

Tnx for help in advance

Hi @lukamacan, thanks for the question,

1. There are a couple different message IDs on any given message. There is the Message ID which is simply an incrementing count of message delivery, but does not uniquely identify a message. This is not available in the Go API. There is the Replication Group Message ID which is guaranteed to be unique within a replication group and should be used when uniquely identifying a message. See GetReplicationGroupMessageID on https://pkg.go.dev/solace.dev/go/messaging@v1.1.0/pkg/solace/message#InboundMessage.
2. If you are using a Go API publisher, you can use the OutboundMessageBuilder from MessagingService.MessageBuilder() , in particular WithSequenceNumber on https://pkg.go.dev/solace.dev/go/messaging@v1.1.0/pkg/solace#OutboundMessageBuilder.

Hope that helps!
