What Protocols Does SMN Support?

SMN supports the following protocols:

HTTP or HTTPS: Messages are sent to subscription URLs by HTTP or HTTPS request. SMN only supports public network URLs and public IP addresses.
FunctionGraph (function): Messages are used as payload to call functions.
DingTalk chatbot: Messages are sent to a DingTalk group through a DingTalk chatbot.
WeCom chatbot: Messages are sent to a WeCom group through a WeCom chatbot.
Lark chatbot: Messages are sent to a Lark group through a Lark chatbot.
- DingTalk chatbot, WeCom chatbot, and Lark chatbot are in the open beta test (OBT). To use these protocols, submit a service ticket to apply for the OBT.
- After the OBT is enabled, your token will be invalid. You need to log in to the console again to use the token. When calling an API, you need to obtain a new token.
- The number of WeCom, DingTalk, and Lark messages that can be sent is limited, and the recipient system may be faulty. As a result, messages may fail to be sent.
  In this case, SMN does not ensure successful message delivery.

Thank you very much for your feedback. We will continue working to improve the documentation.
