# Use webhook triggers
## What is a webhook trigger?
*Webhook triggers* are an effective way to kick off a workflow with context from external systems. By sending an API request to a webhook trigger, Rewst will fire the workflow and include any data and or queries included in the request. For example, when a customer submits a support ticket, a webhook instantly sends that information to Rewst and starts a workflow.
{% hint style="warning" %}
When using webhook triggers, design your workflow with our [rate limiting policy](/rewst-documentation/security/organization-rate-limits.md) in mind.
{% endhint %}
### **Webhook trigger process**
Webhooks follow a simple process:
1. An event happens, such as when a new ticket is submitted.
2. The webhook sends a message with data to a URL.
3. A workflow is triggered based on that message.
### **Webhook URLs**
A *webhook URL* is a unique address where data is received for that particular webhook. It continuously listens for data, and kicks off the related workflow the moment data is received. Once that data is captured, we call it a *payload*, and it becomes usable inside the workflow. This allows you to do things like:
* Assign tasks based on field values
* Push updates to other systems
* Send messages or alerts
* Store or log information for reporting
Webhook URLs are formatted consistently using the trigger ID and organization ID. The format is as follows: `https://engine.rewst.io/webhooks/custom/trigger/{{ Trigger ID }}/{{ Organization ID }}` . Find the webhook URL in the **Details** tab of the trigger node after it's been placed on the Workflow Builder Canvas.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.rewst.help/rewst-documentation/documentation/automations/nodes/nodes-triggers/using-webhook-triggers.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
