Adding Paddle to your Devin app? Let us review it.
Expert review for Paddle integrations built with Devin. We fix Devin-generated Paddle code for security, error handling & production readiness. From $19.
Common Devin issues affecting integrations
Autonomous security decisions
Devin makes security-related decisions without human review — choosing auth strategies, setting permissions, and configuring access controls that may be inadequate.
Compounding architectural errors
When Devin makes an early architectural mistake, it builds subsequent features on top of it. By the time you notice, the issue is deeply embedded in the codebase.
Workarounds instead of fixes
When Devin encounters an error, it sometimes adds workarounds that mask the root cause rather than fixing the underlying issue.
Paddle issues we find in Devin apps
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.
