# Getting started
# Prerequisites
- Approved Application: Ensure your application is approved on AppSumo.
- Redirect URL: Have a Redirect URL that can handle requests from AppSumo.
- Allow Requests: Ensure your server accepts requests from appsumo.com.
# Adding and Testing a Webhook URL
To add your webhook URL, visit the AppSumo Partner Portal (opens new window) and select your product. AppSumo will send a test request to verify the URL, which must respond successfully to be saved.
Before saving, the URL will receive a test POST request containing a "test" field in the body. This request is for verification only, and the accompanying data is not valid.
Your URL must respond with a 200 OK status and a JSON response indicating success = true along with the received event type.
Ensure all test requests return a successful response to confirm that your webhook is functioning correctly.

Example:
{
  "license_key": "00000000-aaaa-1111-bbbb-abcdef012345",
  "event": "purchase",
  "license_status": "inactive",
  "event_timestamp": 1318781876406,
  "created_at": 1318738512,
  "test": true
}
