To synchronize data, such as device and user information, between the IoT Platform and a third-party server, use the HTTP/2 SDK or the AMQP SDK (recommended).
Background information
The following diagram shows how data is synchronized using the HTTP/2 or AMQP (recommended) push method.
Note
- The platform no longer supports enabling data synchronization over HTTP. Device and user data can be synchronized only using HTTP/2 or AMQP (recommended).
- Customers who currently use the HTTP push method are not affected and can continue to use it. However, once disabled, it cannot be re-enabled.
- Customers who use both HTTP to push user data and HTTP/2 to push device data must disable and then re-enable data synchronization. After you re-enable data synchronization, both device and user data can be synchronized only using HTTP/2 or AMQP (recommended).
- Customers who currently use only the HTTP/2 push method can switch directly to the recommended AMQP method. The data format and content remain unchanged.
- Both HTTP/2 and AMQP use a best-effort delivery model. If the cloud does not receive an acknowledgement (ACK) for a message, it adds the message to a retry queue and attempts to push it again. If data accumulates, data for the HTTP/2 method is stored for a maximum of 7 days, and data for the AMQP method is stored for a maximum of 1 day.
Procedure
- On the IoT Platform homepage, click API Service.
- Click Enable to turn on the data synchronization switch.
- Select the products for data synchronization.
By default, data synchronization is enabled for all products after you enable the feature. If needed, you can disable data synchronization for specific products.
