## Duaer Organization Trigger in Duaer

Duaer Organization Trigger is a built-in core node in Duaer for data or flow control. It usually does not need an external SaaS credential.

The product’s node note is: Triggers based on various lifecycle events, like when a Duaer Organization is activated.

## Credentials and parameters

Most core nodes do not need an external credential. If the node still asks for one, create it from the fields it shows.

Parameters accept expressions. Tool parameters that an AI Agent should fill use $fromAI. When a run fails, read the error on the node output first.
## Questions

### How do you add Duaer Organization Trigger to a Duaer digital organization?

Open the node panel on the Duaer canvas, search for Duaer Organization Trigger, and drop it onto the digital organization. Connect it after a trigger or a previous node.

### What should you check first when Duaer Organization Trigger fails in Duaer?

Read the error text on that node’s output, then confirm the credential still works and required parameters are filled. For app nodes, also check permissions and quota on the provider side.
