Mock API Server

Stand up a fake API in a minute: one base URL, any number of routes, every HTTP method — and resources that remember what your client posts, so a full create-read-update-delete flow works before the real service exists.

Running and stopped

Costs & who can call it

A stopped server costs nothing. A running one is billed only when somebody calls it — your free daily allowance first, then tokens.

While a public server is running, anyone with the base URL can call every route. Do not put anything in a response you would mind a stranger reading. Private and protected servers answer only you, or callers with an API key.

Start with a template, or an empty server

Each one gives you a base URL and a set of routes you can edit, add to, or throw away. Point your Spring Boot sandbox, a frontend, or the API Tester at it.

Templates and empty servers are the same thing afterwards — a name, a URL and some routes.

API Tester

Building the order service before the payment service exists? Give this server a /payments resource, point your sandbox's application.yml at the base URL, and test the happy path and the declined path against it. Every call is captured in Request Logs.
