Creating a Subscriber

Scenarios

After you add a subscription to a topic and the subscription is confirmed, the configured endpoints will receive messages published to the topic. If you add the same subscription in multiple regions, the endpoints will receive multiple subscription confirmation messages, and the subscription need to be confirmed in each message. To eliminate such burden, you are advised to add subscribers. After creating a subscriber, you can import it in other regions.

On the Subscribers page, you can centrally manage subscriber information across regions. You can create multiple subscribers and batch subscribe them to a topic.

Subscription data of the Huawei Cloud Chinese Mainland website is stored in the CN North-Beijing4 region, and subscription data of the Huawei Cloud International website is stored in the CN-Hong Kong region.
