# Webhook Payloads

> Context variables available in webhook nodes and the data Asisso sends after a call

Asisso 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. Asisso 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 theme={null}
{
  "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 theme={null}
from fastapi import FastAPI, Request

app = FastAPI()

@app.post("/webhook/asisso")
async def handle_asisso_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 theme={null}
{
  "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/asisso",
    "payload_template": {
      "run_id": "{{workflow_run_id}}",
      "customer": "{{initial_context.customer_name}}",
      "outcome": "{{gathered_context.resolution}}"
    }
  }
}
```
