Adding SendGrid to your Databutton app? Let us review it.
Expert review for SendGrid integrations built with Databutton. We fix Databutton-generated SendGrid 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.
SendGrid issues we find in Databutton apps
Using deprecated v2 Mail Send API
AI tools generate code using the SendGrid v2 API endpoint and format instead of the current v3 Mail Send API, missing features and facing eventual deprecation.
Sender authentication not configured
Generated code sends from addresses without domain authentication (SPF/DKIM), causing emails to fail or be marked as spam by receiving mail servers.
API key has full access instead of restricted permissions
AI tools create and use API keys with full admin access when only Mail Send permission is needed, creating an unnecessary security risk if the key leaks.

Frequently asked questions
Can you review my Databutton-built SendGrid integration?
Yes. We regularly audit SendGrid integrations in Databutton-built apps. We check for proper error handling, security best practices, and production-ready configuration.
What SendGrid issues does Databutton typically create?
Common issues in Databutton-generated SendGrid code include: using deprecated v2 mail send api, sender authentication not configured, api key has full access instead of restricted permissions. We fix all of these in our code review.
How much does it cost to fix my SendGrid integration?
Start with our code audit ($19) to get a complete list of SendGrid issues. Most integration fixes are included in our Fix & Ship plan ($199). For complex integrations, we provide a custom quote after the audit.
What SendGrid 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 SendGrid. Our review checks all of these and provides specific fixes.
