You can't test a Paddle subscription cancel webhook until Paddle has verified your business. That takes days.

Paddle's billing API handles subscriptions, payments, and the entire checkout flow. The API is clean and the docs are solid.

The problem is the sandbox.

Verification before testing

To get a Paddle sandbox account, you need to:

Wait for Paddle to verify your business (this can take days)

Set up products and prices in the sandbox dashboard

Configure webhook URLs

Use test card numbers for checkout

All of this before you can test whether your code correctly handles a subscription.canceled webhook.
