Adding a Subscription

Scenarios

To deliver messages published to a topic to endpoints, you must add the subscription endpoints to the topic. Endpoints can be email addresses, phone numbers, and HTTP/HTTPS URLs. 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 you can 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. However, subscribers will not receive notification messages until they confirm their subscriptions.
   • After you add a subscription, SMN sends a confirmation message to your subscription endpoint. You can confirm the subscription within 48 hours through the confirmation link via your mobile phone, mailbox, or other endpoints.
   • Subscription confirmation messages will be counted as messages sent and will be billed.
