Overview

The Cryptlex Payment Platform Integrations are lightweight webhook servers that automatically synchronize payment events from Stripe, FastSpring, and Paddle with your Cryptlex account. When a customer completes a purchase or subscription payment, these integrations create users, issue licenses, and manage license lifecycles without manual intervention. Built with the Hono framework and TypeScript, these integrations are production-ready and can be deployed to AWS Lambda, Docker, or any Node.js environment.

​
What it does

When a payment event occurs in your payment platform, the webhook server:
  1. Receives and verifies the webhook signature for security
  2. Creates or updates the customer as a Cryptlex user
  3. Issues a new license or renews an existing one
  4. Manages license status based on subscription events (suspend, resume, delete)
All of this happens automatically in real-time as payments are processed.

​
Key features

  • Automatic user creation: Customers from your payment platform become Cryptlex users automatically
  • License lifecycle management: Creates, renews, suspends, and deletes licenses based on payment events
  • Secure webhook verification: All webhook payloads are cryptographically verified before processing
  • Multiple deployment options: Deploy to AWS Lambda, Docker containers, or standard Node.js servers
  • TypeScript and type-safe: Built with strict TypeScript for reliability and maintainability
  • Production-ready: Includes error handling, logging, and tested event handlers

​
Quick example

When a Stripe customer completes checkout: 
{
  "type": "checkout.session.completed",
  "data": {
    "object": {
      "customer_email": "[email protected]",
      "metadata": {
        "cryptlex_product_id": "your-product-id"
      }
    }
  }
}
The integration automatically:
  1. Creates a Cryptlex user with email [email protected]
  2. Issues a license for the specified product
  3. Associates the license with the user
  4. Returns success to Stripe
