Subscribing to Messages from a Specific Group in Azure Web PubSub

Question

Hello Azure Support Team,

I am using the Azure Web PubSub service and have encountered a question regarding message subscriptions.

Context:

• I have successfully created an access token with a specified group.
• My current implementation subscribes to messages from the entire hub, and this is working as expected.

Requirement: I want to adjust my implementation so that I can subscribe to messages only from a specific group within the hub. In essence, I need to receive messages that are broadcasted to a particular group, not from the entire hub.

Details:

• Hub: "Hub"
• Group: "Rishi"

Question: How can I configure my subscription to receive messages exclusively from the specified group? Are there any specific changes or configurations required in the access token generation or in the subscription logic to achieve this?

I appreciate your guidance on this matter.

Thank you.

Best regards, Shreenivas A

@Shreenivas A , Thanks for posting this question.

There is no way to exclude messages from a 'Hub', and it is not supported.
Alternatively, you may not use "SendToAll" (which broadcast to the hub), always use "SendToGroup"
