What does a mock API generator create?

It creates planned HTTP responses for endpoints that frontend, QA, or demo environments can call.

Where can I create the live mock?

Use HttpStatus mocks from the call to action on this page.

Mock API Generator

A mock API generator helps teams create realistic endpoints before the production API exists. Use this guide to plan routes, JSON payloads, response codes, delays, and edge cases.

What to generate first

Start with the screen or integration that is currently blocked. A useful mock API is not a random data generator; it is a small contract that models a real product behavior. For a dashboard, generate endpoints for the current user, summary metrics, filtered tables, and notification counts. For checkout, generate cart, shipping, payment, confirmation, and failure responses.

Mock the happy path, then immediately add the states most likely to break the interface: empty arrays, unauthorized users, validation errors, conflicts, rate limits, slow responses, and server failures. This gives frontend and QA teams stable URLs for the cases they need to exercise every day.

Example mock API plan

GET /api/products
GET /api/products/:id
POST /api/cart/items
POST /api/checkout
GET /api/orders/:id

For each endpoint, define the method, path, request body, response status, response JSON, and scenario name. When the plan is ready, create the hosted mock on HttpStatus mocks.

FAQ

Is a mock API generator the same as a backend?

No. It creates predictable mock responses for development and testing, not production business logic.

Can generated mocks include errors?

Yes. Include 400, 401, 404, 409, 422, 429, and 500 responses so clients handle problems correctly.
