# Webhooks

## Overview

By setting a `webhook` URL in the request to [API Endpoints](/cloud-api/api-endpoints.md#create-anonymization-task), a HTTPS POST request will be sent to the specified URL, as soon as the submitted file has finished processing.

{% code overflow="wrap" %}

```python
payload = {
    "anonymization_method": "blur",
    "face": True,
    "webhook": "https://example.com/webhook/dev?param=test"
}

response = requests.post(
     "https://api.celantur.com/v2/task/", 
      data=json.dumps(payload), 
      headers={'Authorization': auth_token}
 )

```

{% endcode %}

The payload sent to the webhook URL looks like this:

```json
{
    "customer_id": "247d7a0f-f03c-40b9-bed6-b2c4a00c5d80", 
    "task_id": 1693295888421318, 
    "task_status": "done", 
    "anonymized_url": "https://cloudapi-customer-uploads-v2-dev-eu-central-1.s3.amazonaws.com/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/xxxxxxxxxxxxxxxx/1/anonymized.jpeg?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAVKZ73AQDINGO3STH%2F20230829%2Feu-central-1%2Fs3%2Faws4_request&X-Amz-Date=20230829T080023Z&X-Amz-Expires=14400&X-Amz-SignedHeaders=host&X-Amz-Signature=5c99b77982c11da5e9889d3c88c0d2a109270d8c2b0f17d61566ccxxx0495xxx”
}

```

{% hint style="info" %}
Webhooks are especially useful to trigger the download of a file, right after it has finished processing.
{% endhint %}

## Webhook status

The task’s webhook status is either: 

* `empty`
* `set`
* `sent`
* `failed`

The webhook status can be retrieved from the response bodies of [API Endpoints](/cloud-api/api-endpoints.md#get-task) and [API Endpoints](/cloud-api/api-endpoints.md#get-task-status) endpoint.

## Prerequisites for webhooks

* [ ] Make sure you have a publicly available HTTPS endpoint (URL) on your server.
* [ ] Set the webhook URL in the [API Endpoints](/cloud-api/api-endpoints.md#create-anonymization-task) request's JSON body.
