v1 Webhooks (deprecated)

Celantur Cloud API uses webhooks to notify your application when a file has been processed.

Overview

By setting a webhook URL in the request to #upload-image, a HTTPS POST request will be sent to the specified URL, as soon as the submitted file has finished processing.

url = 'https://api.celantur.com/v1/file?method=blur&face=True&webhook='

response = requests.post(
      url, 
      data=image, 
      headers={'Authorization': auth_token}
    )

The payload sent to the webhook URL looks like this:

{
    customer_id={customer_id}
    file_id={file_id}
    file_status="done"
    original_link="https://api.celantur.com/v1/file/{file_id}/original"
    anonymized_link="https://api.celantur.com/v1/file/{file_id}/anonymized"
    binary_mask_link="https://api.celantur.com/v1/file/{file_id}/binary-mask"
    instance_mask_link="https://api.celantur.com/v1/file/{file_id}/instance-mask"
    metadata_link="https://api.celantur.com/v1/file/{file_id}/metadata"
}

Webhooks are especially useful to trigger the download of a file, right after it has finished processing. See #get-anonymized-file

Prerequisites for webhooks

• Make sure you have a publicly available HTTPS endpoint (URL) on your server.

• Set the webhook URL in the #upload-image request's URL parameter.
• Encode the webhook URL correctly

Encode the webhook URL correctly

The webhook URL needs to be encoded correctly, in order to not interfere with the #upload-image endpoint URL:

import requests

...

webhook_url = 'https://example.com/webhook/dev?sender=celantur&approve=always'

# encode the URL you want to send the webhook to
# returns 'https://example.com/webhook/dev?sender=celantur%26approve=always'
webhook_url_encoded = webhook_url.encode()

# set webhook in the POST request
response = requests.post('https://api.celantur.com/v1/file?method=blur&face=True&webhook=' + webhook_url_encoded, 
      data=image, 
      headers={'Authorization': auth_token}
    )
