Can I test Replit API integrations without exposing production credentials?

Goal

Validate Replit API integration logic while keeping production credentials safe.

Constraints

• No documented test token or sandbox mode.
• Environment variables set via the API may not persist across restarts.
• Polling status fields for build/run operations can race if requests are frequent.

Unresolved Decision

How to run integration tests that simulate API interactions on a private Repl without exposing a real user token or affecting shared Repls.

Questions

• Which method can safely emulate Replit API calls while protecting production credentials?
• Does Replit provide any flag or endpoint to mark requests as test or dry‑run?
• Can environment variables set through the API reliably survive a Repl restart during automated testing?
