# WeCom suite callback trigger

Receive WeCom third-party suite instruction callbacks in Duaer. You need a suite receive credential.
## When to use it

Use this only for third-party suite (ISV) callbacks. For self-built app messages, use [WeCom message receive trigger](/integrations/builtin/trigger-nodes/duaer-nodes-wecom.wecomtrigger.md).
## Questions

### Do self-built apps need this?

Usually no. Self-built apps use the message receive trigger.
