What Is HTTP 200 OK?

HTTP 200 OK explained, and what it means when you see it in CI/CD and deployments.

HTTP 200 is the standard success response for a completed HTTP request.

What it means

A 200 status means the server processed the request and is returning the expected body. It is the baseline "everything worked" response for GET and many POST requests.

When you see it in CI/CD

CI smoke tests and deploy health checks typically assert a 200 from a service URL before marking a deploy healthy. A curl -f fails the step on any non-2xx, so a 200 is the green light.

Key takeaways

• 200 means the request succeeded.
• Health checks assert 200 to confirm a deploy.
• curl -f treats non-2xx as failure.
