# Mock Servers | Postman API Platform

> Spin up a mock server from any collection or spec in seconds. Configure exactly what each endpoint returns, simulate network delays, and let your team start building without waiting on backend teams.

## Mock Servers

Ensure your API delivers the right behavior when it hits production.

## Simulate any API response exactly the way you need it

### One-click mock creation

Get started fast by creating a mock from a collection, a spec, or your request history.

### Smart response matching

Postman matches incoming requests to your saved examples by URL, method, body, and headers.

### Public or private access

Keep mocks locked down with API key auth or make them public for any client or CI pipeline to hit directly.

---

## Create mock servers with a single prompt

Use Postman AI to read your spec and create realistic response examples for every endpoint, including edge cases and error states.

*CAPABILITIES*

### Everything you need to prototype, test, and iterate on APIs

Mock servers remove the backend from the critical path. Configure responses, match requests precisely, and give every team member a stable API surface to build against.

### Simulate API responses without waiting on the backend

Spin up a mock server from any collection or spec and enable your team to test and develop new functionality before your API is production-ready.

### Test behavior under real-world conditions

Set a fixed response delay on any mock server to see how your app behaves under slow or degraded network conditions.

### Create a local mock in your Git repo with Native Git

Simulate API behavior before committing changes to the Postman Cloud by creating a local mock server that's stored in your local Git repository.

### Call log

See a list of calls made to the mock server URL, including the time the request was sent, the request method and path, and a response overview.

### Postman API access

Create, configure, and manage mock servers programmatically via the Postman API.

### Response matching

Enable header and request body matching to filter mock responses by exact header values and body content, with Postman returning the highest-scoring example match.

> Mock servers removed development dependencies. Postman allows API development, testing and releases to be run in parallel. There's no waiting for API implementation to be completed.

## Broken collaboration leads to broken APIs.

Ninety-three percent of API teams still face collaboration blockers. The 2025 State of the API report reveals how you can unlock the productivity gains that API-first promises, but scattered tooling prevents.
