# Synchronous Subscriptions
|
|
|
|
Synchronous subscriptions require the application to wait for messages.

For situations where a single message is expected, synchronous subscriptions are sometimes easier to manage, depending on the language.

For example, to subscribe to the subject `updates` and receive a single message you could do:

!INCLUDE "../../_examples/subscribe_sync.html" |
