Integrate third-party APIs faster by using "Postman API" ready-to-use mock sample. Mocking this API will allow you to start working in no time. No more accounts to create, API keys to provision, accesses to configure, unplanned downtime, just work.

You can also use the Postman API to get the mock server’s URL. The POST /mocks endpoint returns the URL in the response when it creates the mock server. If you need to get the URL, make a request to the GET /mocks endpoint and copy the mockUrl value. You’re ready to simulate requests using your testAPI collection.

This collection defines the API implemented by the [Fake API Server](https://github.com/jmather/node-fake-api-server) and consumed by the [Fake API Client](https://github.com/jmather/node-fake-api-client)

Create mock servers in Postman to help with API development and testing. A mock server simulates a real API server by accepting requests and returning responses. By configuring a mock server for your collection and adding examples to your requests, you can simulate the behavior of a real API.

June 10, 2025 - Postman is an API testing tool that helps developers and testers make HTTP requests, inspect responses, automate tests, and much more — all with a user-friendly GUI. ... Let’s use https://dummyjson.com — a fake REST API for testing.

November 8, 2022 - ... This method will send data to the resource and create a new product called “BMW Pencil”. To do that in Postman, just create new request, ensure the method is POST, Insert the URL of the endpoint.

In this tutorial, you’ll learn how mock servers and examples work together and how to integrate them into your API workflow. To get started, you’ll need to create a collection and an example response. In the sidebar, click and select New Collection. Give the collection the “C1” name.

July 23, 2025 - ... Navigate to the collections tab on the left side of the navigation bar, then click on the mock server api collection which we created and select users. Next, click on the send button on the top right hand of your postman to see sample JSON ...

Use a mock server to simulate a server for your API requests without having to configure one. You can use any HTTP collection to set up a mock server.

This is an advanced API testing project focused on user authentication workflows, built using Postman. It covers both positive and negative test cases for token-based login and secure API access, simulating a real-world login system.

With Postman's mock API servers, you can design, build and test your APIs. See how your API runs before it's in production, and speed up design and development.

This mock server leverages Beeceptor features to provide a free and openly accessible fake REST API. This is ideally suited for testing and prototyping. There are a variety of endpoints available and each provides JSON response for resources ...

February 9, 2023 - I would like some kind of internal request URL that is trapped by Postman and does not result in any calls made beyond the Postman app. This would have the advantage of being much quicker to respond than any external call. I would use this as the URL in my First-Call in the sequence. The request would return 200 OK, by default, with no, or a minimal, payload, but maybe could take parameters and return the response specified in the parameter. This sub-feature could allow testers and developers to test assertions and test actions in their code efficiently, maybe even when their objective system is still in development.

October 28, 2024 - Apidog's Mock Server can generate user-friendly dummy data even without set rules due to its Smart Mock feature. The platform thus provides an efficient way for API development and testing.

This page will list all of the rest services. These are fake online REST APIs for testing and prototyping sample applications that use rest calls to display listings and crud features.

JSONPlaceholder is a free online REST API that you can use whenever you need some fake data. It can be in a README on GitHub, for a demo on CodeSandbox, in code examples on Stack Overflow, ...or simply to test things locally.

This feature will be utilised in this tutorial to share variables between API calls in the collection. Environment Variables: Tied to a specific environment, making it easy to switch between setups. Data Variables: Used in collection runs with external data files (CSV or JSON), allowing dynamic inputs for automated testing. Local Variables: Temporary variables that exist only during a request and are not stored beyond execution. Useful for non-persistent data when making multiple calls in a loop.
