Adding a Subscription¶
Scenarios¶
To deliver messages published to a topic to endpoints, you must add the subscription endpoints to the topic. The endpoint can be a mail address, a mobile phone number, or an HTTP/HTTPS URL. After you add endpoints to the topic and the subscribers confirm the subscription, they are able to receive messages published to the topic.
You can add multiple subscriptions to each topic. This section describes how to add a subscription to a topic you created or a topic that you have permissions for and how to delete a subscription.

Note
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 of time. For details, see Traffic Control over Subscription Confirmation.
SMN does not check whether subscription endpoints exist when you add subscriptions. However, subscribers will not receive notification messages until they confirm their subscriptions.
After you add a subscription, SMN sends a confirmation message to the subscription endpoint. You can confirm the subscription within 48 hours through the confirmation link via your mobile phone, mailbox, or other endpoints.
