API Gateway Entry

Why the gateway stays stateless

• Connection handling

  • TLS termination and HTTP parsing.

  • Enforced request size limits and timeouts.

• Request shaping

  • Basic validation (method, path, required fields).

  • Normalization of query parameters and pagination knobs.

• Trace context

  • A unique request identifier is created.

  • The identifier is propagated to downstream services.

  • The identifier is returned to clients on success and failure.

What happens at the edge

The gateway stays thin. It does not implement protocol logic.

All client traffic enters through the API gateway. It is the only public-facing entry point.

• Enables horizontal scaling behind a load balancer.

• Makes rollouts safer.

• Prevents sticky-session coupling.

If you open a support ticket, include the request identifier. It is the fastest path to root cause.
