Handling Webhooks

To handle webhooks, you need to set up an endpoint in your application that can receive HTTP POST requests from Crossmint. Here’s an example of how you might handle a webhook in a Node.js application:

// Example webhook handler
app.post("/webhooks", (req, res) => {
    const event = req.body;

    switch (event.type) {
        case "users.created":
            handleUserCreated(event.data);
            break;
        case "users.updated":
            handleUserUpdated(event.data);
            break;
        default:
            console.log(`Unhandled event type: ${event.type}`);
    }

    res.sendStatus(200);
});
