Integration overview

The Processing Webhook integration is an easy way to perform processing or analysis operations on a remote server via a simple HTTP request. It will enable you to easily integrate your own processing logic and behaves as follow:

  • Perform an HTTP POST to the address specified in parameter
  • Store the return of the HTTP request for subsequent processing in the workflow or to be permanently saved to the stack store

The integration provides two ways to send the data in the webhook request:

  • Using a presigned URL in a JSON payload, which allows you to fetch the object and its metadata with a simple HTTP Get
  • Post the data as a Multipart-Encoded File in a multipart/form-data request

Send the data with a presigned URL

This way of sending the data to processed is the default mode and the prefered way as it provides more flexibility. The metadata of the object can easily be retrieved as they will be in the header when you fetch the file.

The payload is a simple JSON:

    "object": {
        "key": "MYFILE.jpg",
        "url": ""

Send the data in a form encoded fashion

The form encoded option doesn't require you to implement logic to fetch the file as you'll directly receive the payload. The metadata will not be sent.

To simulate the call you'll receive, can you simply use curl:

curl -F file=@myfile.txt

Input data

You can use the Webhook integration to process any kind of data. The integration is completely data agnostic and will allow remote processing of images, videos, PDFs, text or any binary data.

Output data

The webhook integration will return the result of the calls to the remote service with one file per call.
