Stripe Checkout - Part 2: Webhook & Linking Xano Users to Checkout Sessions

In this tutorial, we'll dive into Part 2 of the Stripe Checkout integration with Xano. We'll cover how to set up a webhook to track user sessions and purchases, as well as how to link user data to the checkout sessions for better tracking and management.

Setting Up the Stripe Webhook

First, let's set up the Stripe webhook that will allow us to capture essential data from the checkout process.

1. Head over to the Xano marketplace page and locate the Stripe integration.
2. Take note of the different events available for the webhook, such as `checkout.session.completed`, `checkout.session.async_payment_failed`, and `checkout.session.async_payment_succeeded`.
3. Navigate to the Stripe Developer Portal and go to the "Webhooks" section.
4. Click "Add an Endpoint" and paste the webhook URL provided by Xano.
5. Select the events you want to track, for example, `checkout.session.completed`.
6. Click "Add Endpoint" to save the webhook.

You can even test the webhook by sending a test event from the Stripe Developer Portal. This will allow you to see the request payload and ensure that the webhook is working correctly.

Tracking User Sessions

In some cases, you may want to track the sessions created by each user in your application. This can be useful for various purposes, such as analyzing purchasing patterns, managing subscriptions, or providing personalized experiences.

To achieve this, follow these steps:

1. In Xano, navigate to your data model and add a new table reference field to the `sessions` table. This field will link each session to a specific user in your `users` table.
2. Next, go to the API endpoint responsible for creating a new checkout session (e.g., `create_session`).
3. Enable user authentication for this endpoint, ensuring that only authenticated users can create new sessions.
4. Within the endpoint's code, add a new database request to insert a record into the `sessions` table. Populate the necessary fields, such as `created_at`, `session_id`, and `user_id` (using the `auth.userId` to link the session to the authenticated user).
5. Modify the webhook endpoint (`handle_webhook`) to update the existing session record instead of creating a new one. Use the `addOrEditRecord` database request with the `session_id` as the lookup field. This way, when the webhook is triggered, it will update the session record with the latest information from Stripe (e.g., payment status, customer details).

By following these steps, you'll be able to track each user's checkout sessions within your Xano database, making it easier to manage and analyze purchase data.

Conclusion

In this tutorial, we covered how to set up a Stripe webhook in Xano to capture checkout session events. Additionally, we explored a method to link user data to checkout sessions, enabling better tracking and management of user purchases within your application.

Remember, Xano's no-code platform simplifies the process of building backend services, making it accessible to both non-technical users and developers alike. Leverage its visual interface and pre-built integrations to streamline your development process and bring your ideas to life faster.
