Adding Slack API to your Cursor app? Let us review it.
Expert review for Slack API integrations built with Cursor. We fix Cursor-generated Slack API code for security, error handling & production readiness. From $19.
Common Cursor issues affecting integrations
Exposed API keys in client code
Cursor often places sensitive keys and secrets directly in client-side components or .env files without the NEXT_PUBLIC prefix distinction, making them accessible in the browser.
Missing input validation on API routes
Server actions and API routes generated by Cursor frequently accept user input without sanitization or schema validation, opening the door to injection attacks.
Unhandled async errors
Cursor wraps code in try/catch inconsistently. Failed API calls, database queries, and file operations often crash the app silently or show raw error messages to users.
Slack API issues we find in Cursor apps
Request signature verification missing
AI-generated Slack webhook handlers don't verify the X-Slack-Signature header, allowing anyone to send fake events to your endpoint.
Not responding within 3 seconds to events
Generated event handlers try to process everything synchronously before responding, causing Slack to retry events and eventually disable your endpoint due to timeout.
Bot token and user token confused
AI tools use the bot token for actions that require a user token (or vice versa), causing permission errors or posting messages as the wrong entity.
