MockAPI is a simple tool that lets you easily mock up APIs, generate custom data, and perform operations on it using RESTful interface. MockAPI is meant to be used as a prototyping/testing/learning tool.

February 28, 2024 - An API mock is a web service that simulates a real, functional service. A mock can be used to provide example responses from the backend service that is currently being developed, which makes it a great fit for the use case we described above.

WireMock is a tool for building mock APIs. API mocking enables you build stable, predictable development environments when the APIs you depend on are unreliable or don’t exist.

February 5, 2026 - API mocking involves creating a simulated version of the real API to help testers carry on with their testing activities in case the actual API is not available

Get working mock REST APIs in seconds with an intuitive and easy-to-use interface.

Learn how to quickly mock data to design, build, and test APIs using a mock or dummy API Server.

Web APIs are usually implemented as HTTP endpoints. Playwright provides APIs to mock and modify network traffic, both HTTP and HTTPS. Any requests that a page does, including XHRs and fetch requests, can be tracked, modified and mocked.

August 18, 2025 - Instead of sending requests to a live backend service, API mocking returns predefined responses, allowing developers and testers to work with the API’s expected behavior even if the real service is incomplete, unavailable, or still being developed.

Mock Service Worker is an API mocking library that allows you to write client-agnostic mocks and reuse them across any frameworks, tools, and environments.

Effortlessly manage all synchronous and event-driven APIs by leveraging OpenAPI, AsyncAPI, gRPC/Protobuf, GraphQL schemas and even SOAP. Microcks offers a single, comprehensive tool to handle everything, boosting productivity and cutting costs.👉 Lombard Odier's Success Story with Microcks · Microcks offers customizable mocking: re-use, generate realistic examples or transform mock data and responses on the fly.

Testing your REST & SOAP APIs, both internal and external, is critical in producing quality software that works for the end user in a manner that it's supposed to. Learn the in's and out's of API testing.

Leverage native API mocking to create mocks with dynamic responses manually or automatically from OpenAPI specs, API responses or natural language.

API mocking is the practice of creating simulated responses to API requests, mimicking the behavior of a real backend. These mock APIs can return predefined data, simulate errors, or even replicate complex workflows like authentication and rate ...

April 3, 2025 - Ensure that 200 OK, application/json appears in the API Management response box. This selection indicates that your API should return the response sample that you defined in the previous section. Select Save. ... A yellow bar displaying the text Mocking is enabled appears.

API mocking is the process of simulating API responses without relying on the actual backend server. It allows developers and testers to create mock responses to API calls, making development and testing faster, more flexible, and independent ...

Reduce time to market by letting frontend and backend teams develop simultaneously, without waiting for the development stage of the API to complete.Learn More · Validate requests and responses against your OpenAPI file. Stoplight mocks simulate real server behavior by automatically validating incoming request headers, query strings, and request bodies against your OpenAPI description.Learn More

August 21, 2025 - Mock APIs are used to simulate actual APIs where you can generate requests with custom data and get realistic responses the actual API would return. It is a fast and easy way of testing your REST API even before it goes live.

Using Mocki you can create, run and deploy mock APIs. Use your mocks to design your API, serve static responses, simulate error scenarios and remove dependencies to external services. Sign up today for a free 7-day trial.

April 9, 2025 - API mocking provides a stable and predictable testing environment. By simulating API responses, you can ensure that your tests are consistent and free from external variables like network issues or API downtimes.
