Adding Slack API to your Codex CLI app? Let us review it.
Expert review for Slack API integrations built with Codex CLI. We fix Codex CLI-generated Slack API code for security, error handling & production readiness. From $19.
Common Codex CLI issues affecting integrations
API keys and secrets written directly into generated source files
Codex CLI generates code with placeholder credentials that developers often replace with real values inline, leaving secrets committed to version control. There is no .env scaffolding or secret management setup by default.
No authentication or authorization on generated API endpoints
When Codex generates Express or FastAPI backends, routes are created without middleware for authentication, meaning every endpoint is publicly accessible immediately after deployment.
Single-file output breaks apart for any real project structure
Codex frequently outputs all logic into one or two files rather than organizing code into modules, services, and utilities — making the result hard to maintain and extend as the codebase grows.
Slack API issues we find in Codex CLI 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 Codex CLI-built Slack API integration?
Yes. We regularly audit Slack API integrations in Codex CLI-built apps. We check for proper error handling, security best practices, and production-ready configuration.
What Slack API issues does Codex CLI typically create?
Common issues in Codex CLI-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 Codex CLI 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.
