description: "Context variables available in webhook nodes and the data Dograh sends after a call"
---

Dograh executes **webhook nodes** asynchronously after a workflow run completes. You configure the target URL, HTTP method, headers, and payload template directly in the workflow definition.

---

## How webhooks work

1. A call completes (or a run finishes)
2. Dograh executes any `webhook` nodes in the workflow asynchronously
3. The payload template is rendered with the run's context and sent as a JSON `POST` (or your configured method) to your endpoint
4. Non-200 responses are logged but do not block or retry by default (configure `retry_config` to change this)

---

## Payload context variables

The following variables are available in your `payload_template` using double-brace syntax (e.g. `{{workflow_run_id}}`):

| Variable | Type | Description |
|---|---|---|
| `workflow_run_id` | integer | ID of the completed run |
| `workflow_run_name` | string | Name of the run |
| `workflow_id` | integer | ID of the workflow |
| `workflow_name` | string | Name of the workflow |
| `campaign_id` | integer \| null | ID of the campaign this run belongs to (null for ad-hoc runs) |
| `call_time` | string | ISO-8601 UTC timestamp of when the run was created |
| `initial_context` | object | Context passed when the call was initiated |
| `gathered_context` | object | Data extracted during the call by agent nodes |
| `cost_info` | object | Call cost breakdown |
| `annotations` | object | QA analysis results (if a `qa` node is configured) |
| `recording_url` | string \| null | Public download URL for the call recording |
| `transcript_url` | string \| null | Public download URL for the call transcript |

### Example payload template

```json
{
  "run_id": "{{workflow_run_id}}",
  "customer": "{{initial_context.customer_name}}",
  "outcome": "{{gathered_context.resolution}}",
  "recording": "{{recording_url}}"
}
```

## Authentication

Webhook requests support the following authentication methods, configured via a stored credential:

| Type | Description |
|---|---|
| `NONE` | No authentication |
| `API_KEY` | Sends the key in a custom header (e.g. `X-API-Key`) |
| `BEARER_TOKEN` | Sends `Authorization: Bearer <token>` |
| `BASIC_AUTH` | HTTP Basic authentication (username + password) |
| `CUSTOM_HEADER` | Any custom header key-value pair |

---

## Receiving webhooks

Your endpoint should:

- Accept `POST` requests with `Content-Type: application/json`
- Respond with a `2xx` status code promptly (within 30 seconds)
- Handle duplicate deliveries idempotently (retries may deliver the same payload more than once)

### Minimal example receiver (Python)

```python
from fastapi import FastAPI, Request

app = FastAPI()

@app.post("/webhook/dograh")
async def handle_dograh_webhook(request: Request):
    payload = await request.json()
    run_id = payload.get("run_id")
    outcome = payload.get("outcome")
    # process the call result...
    return {"status": "ok"}
```

## Webhook node in a workflow definition

See [Workflow Definition Schema](/developer/workflow-schema#webhook-node) for the full configuration reference.

```json
{
  "id": "webhook-1",
  "type": "webhook",
  "position": { "x": 600, "y": 0 },
  "data": {
    "name": "Notify CRM",
    "enabled": true,
    "http_method": "POST",
    "endpoint_url": "https://your-service.com/webhook/dograh",
    "payload_template": {
      "run_id": "{{workflow_run_id}}",
      "customer": "{{initial_context.customer_name}}",
      "outcome": "{{gathered_context.resolution}}"
    }
  }
}
```
