Adding a Subscription¶
Scenarios¶
To enable an endpoint to receive messages published to a topic, you must subscribe the endpoint to the topic. The endpoint can be a phone number, email address, function, or an HTTP/HTTPS URL. After you subscribe an endpoint to a topic and the subscription is confirmed, the endpoint can receive messages published to the topic.
You can add multiple subscriptions to a topic. This section describes how to add a subscription to a topic you created or a topic that you have permissions for.

To prevent malicious users from attacking subscription endpoints, SMN limits the number of confirmation messages that can be sent to an endpoint within a specified period. For details, see Traffic Control over Subscription Confirmation.
SMN does not check whether subscription endpoints exist when you add subscriptions.
After you add a subscription or request subscription confirmation, SMN will send a confirmation message to the endpoints, and the link in the confirmation message will be valid for 48 hours.
Subscription confirmation messages will be counted as messages sent and will be billed.
