Validate Purchases with Server-Side Webhooks

Merchants can now securely confirm completed purchases and trigger powerful post-purchase workflows—like granting access, sending emails, or updating analytics—in real time.

What’s new

We’ve introduced two key features to help merchants validate purchases securely:

1. Webhooks that notify your server when a purchase is complete
2. Enhanced client-side callbacks that include detailed purchase data

Why it matters

For high-value services—like generative AI or premium content—client-side validation isn’t enough. This release enables secure, server-side confirmation of purchases before access is granted, reducing fraud and protecting merchant resources.

What you can do with it

Server-side webhooks unlock a wide range of automation and security options:

• Secure Access Control — Grant access to content or services only after a verified purchase.
• Personalized Onboarding — Kick off welcome emails, setup flows, or user provisioning.
• Real-Time Analytics — Sync purchase data with internal dashboards or CRMs.
• Customer Support Workflows — Create support tickets or alerts when purchases happen.
• Loyalty & Rewards — Automatically assign points or trigger reward logic based on purchases.

How it works

• Enable webhooks from the new Webhooks tab in the Business Portal. We use Svix to deliver events like purchase.added, including key purchase metadata.
• Use the updated onPurchaseComplete callback in Tab.js to access purchase ID, user ID, and other validation data.
• Webhooks also work in Test Mode, so you can safely build and test your integration.

This gives you end-to-end purchase security and the flexibility to build powerful merchant-side workflows. Want to see it in action? Reach out for a demo or setup support.
