See Exactly How Your API will Run—Even Before It's in Production
API design is the key to building quality APIs that last. Postman's mock servers simplify API design and planning, support split-stack development, and help you ensure that your API will run the way it's supposed to in production.
Build Higher Quality APIs
Shorten Time to Production
Work more efficiently with Postman's API mock servers. Postman mocks support split-stack development so front-end and back-end developers can work in parallel and view responses without spinning up the back end.
Design Your API with Flexible Schema Support
Postman mock servers compliment Postman's extended schema support. Write, edit, or import your API schema to define your API's data structure and generate a collection from your API schema. You can review API responses using mock servers so you can reliably build your API from the ground up—all in one central place.
Visualize the Expected Behavior of Your API
Postman Mock Servers allow you to view API responses with the applications and services waiting to use it before and during development. Postman Mocks show you how your API will run in production—without the risk!
Catch and Fix Bugs Early
Mock servers increase visibility into errors and weak spots in your API, so you can debug effectively and efficiently. You can easily use mock servers to test for response errors continuously or as often as you need throughout the API lifecycle.
Create Public or Private Mock Servers in Postman
Postman provides two different types of mock servers. Public mock servers are great for open source or individual projects, but if you're working on internal or private APIs, you can easily keep your APIs secure by viewing API responses with private mock servers.
