What is sb protocol and how is works internally?

Question

I have configured a notification hub using Azure portal for implementation of push notifications for mobile apps. On navigating to the Access Policies section, I see couple of policies with names: DefaultListenSharedAccessSignature and DefaultFullSharedAccessSignature as shown in the below diagram. Both the policy names contain connection string. One of the connection string is as follows:

Endpoint=sb://expedia.servicebus.windows.net/;SharedAccessKeyName=DefaultFullSharedAccessSignature;SharedAccessKey=JnVgQvxxxxxxxxxxxxxxxxxxxxxxxy1HgWUfUo=

I want to understand what is sb protocol here and want to how it works internally and does it depends on HTTPS.

I have to access the above endpoint from a remote server. How to consider the above while white listing the proxy rules to allow access to the above endpoint.

sb is just an endpoint schema that we understand, and it's not an actual protocol. The actual protocol is https.

Turns out sb means "Service Bus" and it appears to basically be Webhooks as a Service... – whodini9 Nov 28 '17 at 18:08
do you have Microsoft documentation for this? I can't find it. – seabass Nov 15 '18 at 15:51
It's interesting to note that sb is also used for Azure Event Hubs, when creating the connection string for example. – David Klempfner Dec 11 '22 at 02:04

According to a more broadly framed Service Bus FAQ, they detail the ports that are used by sb:// which uses both HTTPS (443) and AMQP (5671, 5672)
