# Start a Duaer digital organization with WhatsApp Trigger

WhatsApp Trigger in Duaer is a trigger node: it starts a digital organization instead of running a step after the run has already begun. Node note: Handle WhatsApp events via webhooks
## WhatsApp Trigger in Duaer

WhatsApp Trigger is a trigger node in Duaer: when an event arrives or a condition is met, it starts a digital organization.

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

## Credentials and parameters

Credential notes are under [WhatsApp Trigger credentials](/integrations/builtin/credentials/whatsapp.md).

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 WhatsApp Trigger to a Duaer digital organization?

Open the node panel on the Duaer canvas, search for WhatsApp 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 WhatsApp 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.
