Fix Your AI-Built Paddle Integration
Merchant of record payment platform handling tax and compliance. AI tools frequently mishandle Paddle's unique pricing model and webhook verification.
Common Paddle issues we find
Problems specific to AI-generated Paddle integrations.
Webhook signature verification using wrong algorithm
AI tools often generate webhook verification code using HMAC-SHA256 when Paddle Classic uses RSA public key verification, or mix up Classic and Billing API patterns.
Confusing Paddle Classic with Paddle Billing APIs
Generated code mixes API calls from Paddle Classic and the newer Paddle Billing, which are incompatible and use different authentication methods.
Incorrect price handling with tax-inclusive amounts
AI tools display prices without accounting for Paddle's tax-inclusive model, showing users incorrect totals or double-counting tax.
Missing subscription lifecycle event handling
Generated code only handles the initial payment success event and ignores cancellation, past-due, and pause events that are critical for access control.
Client-side token exposed in build output
AI tools place the Paddle API key in client-side code instead of using the separate client-side token, exposing your full API credentials.

Frequently asked questions
Why are prices showing incorrectly in my AI-built Paddle checkout?
Paddle handles tax as a merchant of record, meaning prices you set may be tax-inclusive. AI tools often treat the price as tax-exclusive and try to add tax on top, resulting in incorrect totals. A review ensures your pricing logic matches Paddle's model.
How do I migrate AI-generated Paddle Classic code to Paddle Billing?
The APIs are completely different -- different endpoints, authentication, webhook formats, and event types. AI tools frequently generate a hybrid that works with neither. A clean migration requires rewriting webhooks, updating API calls, and changing price ID references.
Is my AI-generated Paddle integration handling refunds correctly?
Most AI-generated integrations only handle the happy path. Paddle refund events need to revoke access, update subscription state, and handle partial refunds differently from full refunds. We audit the full refund flow end to end.
