The product’s node note is: Handle Wufoo events via webhooks.

## Credentials and parameters

Create the credential type this service needs under Credentials.

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 Wufoo Trigger to a Duaer digital organization?

Open the node panel on the Duaer canvas, search for Wufoo Trigger, and drop it onto the digital organization. Use it as the start. If auth is required, save the credential first and select it on the node.

### What should you check first when Wufoo 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.
