Events

Purchase events, delivered.

Receive purchase and product access events in your own systems without polling the API.

Create an endpoint

Give Nexus an HTTPS endpoint from your dashboard and select the events it should receive. Every delivery includes an event ID so it can be processed safely more than once.
