Common GPT Engineer issues affecting integrations

security

No authentication system

GPT Engineer generates functional UIs but typically skips authentication entirely. All routes and data are publicly accessible.

security

Direct database access from client

Some generated apps query databases directly from the frontend without an API layer, exposing database credentials and structure.

bugs

Incomplete feature implementations

Features that look complete in the UI but don't actually work end-to-end. Buttons that don't submit, forms that don't save, and links that go nowhere.

Slack API issues we find in GPT Engineer 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.

Frequently asked questions

Can you review my GPT Engineer-built Slack API integration?

Yes. We regularly audit Slack API integrations in GPT Engineer-built apps. We check for proper error handling, security best practices, and production-ready configuration.

What Slack API issues does GPT Engineer typically create?

Common issues in GPT Engineer-generated Slack API code include: request signature verification missing, not responding within 3 seconds to events, bot token and user token confused. We fix all of these in our code review.

How much does it cost to fix my Slack API integration?

Start with our code audit ($19) to get a complete list of Slack API issues. Most integration fixes are included in our Fix & Ship plan ($199). For complex integrations, we provide a custom quote after the audit.

What Slack API best practices does GPT Engineer 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 Slack API. Our review checks all of these and provides specific fixes.
