Expert review for Resend integrations built with Databutton. We fix Databutton-generated Resend code for security, error handling & production readiness. From $19.
Common Databutton issues affecting integrations
SQL injection in AI-generated query strings
Databutton's generated FastAPI endpoints sometimes build SQL queries using f-strings or string concatenation with user-supplied parameters, bypassing parameterized query protections entirely.
No authentication on data API endpoints
Data pipeline endpoints are frequently generated without authentication middleware, exposing raw database access and sensitive business metrics to anyone who discovers the API URL.
Unhandled data type mismatches crashing pipelines
Generated data processing code assumes clean input schemas. When upstream data contains nulls, type changes, or unexpected formats, pipelines throw unhandled exceptions and fail silently.
Resend issues we find in Databutton apps
API key exposed in client-side code
AI-generated code calls the Resend API directly from the browser, exposing the API key and allowing anyone to send emails from your domain.
Sending from unverified domain
Generated code sends emails from a domain that hasn't been verified in Resend's dashboard, causing all emails to fail or land in spam.
No rate limiting on email-sending endpoints
AI tools create API routes that call Resend without any rate limiting, allowing attackers to abuse your endpoint to send thousands of spam emails on your account.

What Resend issues does Databutton typically create?
Common issues in Databutton-generated Resend code include: api key exposed in client-side code, sending from unverified domain, no rate limiting on email-sending endpoints. We fix all of these in our code review.
How much does it cost to fix my Resend integration?
Start with our code audit ($19) to get a complete list of Resend issues. Most integration fixes are included in our Fix & Ship plan ($199). For complex integrations, we provide a custom quote after the audit.
What Resend best practices does Databutton typically miss?
AI tools often skip webhook signature verification, proper error handling for API failures, retry logic with exponential backoff, and secure token storage for Resend. Our review checks all of these and provides specific fixes.
