P5. API/backend path

What this page helps you do

Focus on the launch work that matters most when your product is mainly an API or backend service.

Why it matters

Backend services can look healthy from the outside right until clients start getting timeouts, auth failures, or bad data.

You should already have

  • an API or backend service that other apps, clients, or jobs depend on

Skip this page if

  • the main product is a browser app for end users

Then go to P2. SaaS web app path.

What to do

Make health checks, logs, and rollback part of the first launch, not a later cleanup.

Common mistakes

  • shipping without a health endpoint or clear diagnostics
  • exposing admin routes too openly
  • not knowing which clients depend on which environment variables

Next step

Go to F4. Run your app locally.

Advanced notes

TODO for contributors: add examples for API auth, rate limiting, and deploy smoke tests.
