Webhooks allow API users to receive automatic push notifications for item updates. Webhooks both reduce bandwidth and improve notification speed as compared to traditional API calls.
You can access and configure webhooks via My GunBroker > Toolbox > Webhooks.
From here, simply enter your Base API URL, API Username, and Password, as shown below.
In the Configure Webhook Settings section that follows, be sure to enable your selected webhooks via the toggle on the left and enter the Endpoint to match the related listener on your API (which would be https://api.example.url/ItemsSold for the "Items Sold" line in the example above).
Note: Endpoints should be entered without slashes ( / )
For additional details on each Webhook, please see the GunBroker.com REST API Help links below:
