The **Webhook** component defines a webhook trigger that runs a flow when it receives an HTTP POST request.
|
|
|
|
## Trigger the webhook
|
|
|
|
When you add a **Webhook** component to your flow, a **Webhook curl** tab is added to the flow's [**API Access** pane](/concepts-publish#api-access).
|
|
This tab automatically generates an HTTP POST request code snippet that you can use to trigger your flow through the **Webhook** component.
|
|
For example:
|
|
|
|
```bash
|
|
curl -X POST \
|
|
"http://$LANGFLOW_SERVER_ADDRESS/api/v1/webhook/$FLOW_ID" \
|
|
-H 'Content-Type: application/json' \
|
|
-H 'x-api-key: $LANGFLOW_API_KEY' \
|
|
-d '{"any": "data"}'
|
|
```
|
|
|
|

## Webhook parameters

|------|--------------|-------------|
|
|
| data | Payload | Input parameter. Receives a payload from external systems through HTTP POST requests. |
|
|
| curl | curl | Input parameter. The curl command template for making requests to this webhook. |
|
|
| endpoint | Endpoint | Input parameter. The endpoint URL where this webhook receives requests. |
|
|
| output_data | JSON | Output parameter. The processed data from the webhook input. Returns an empty [`JSON`](/data-types#json) object if no input is provided. If the input isn't valid JSON, the **Webhook** component wraps it in a `payload` object so that it can be accepted as input to trigger the flow. |
