The API notifies the URL of your choice asynchronously at each operation performed by your e-commerce application via a POST call. On your side, you have to create a specific page to handle the content of this notification. It does not need to display any particular information, but you will find the content of your response on your customer area.Once this page has been created and put online, it must be set up in Easytransac, on the e-commerce application, in the "notification URL" field.The raw data sent via webhook in the POST request body is formatted as JSON. Ensure your endpoint can parse JSON to handle the notification content properly.
