Design Data

Choose from 100+ built-in data types, upload your own reference data, or build your own using Mockaroo's formula API

Build Routes

Mimic your real API, including URL, path variables, query string, and entity body. Map request parameters to your schema then generate dynamic data, simulate errors, or simply return static data.

Send Requests

Swap out your domain for my.api.mockaroo.com in development and start firing off requests. Pass your API key in the query string or via an X-API-Key header.

Easy as 1, 2, 3...

Step 1: Create a Schema

Use Mockaroo's data designer to design a format for the response.

Step 2: Create a Mock API

Define a URL and specify how the response is generated. You can map incoming request parameters to parameters in your schema, augment generated data with static values, conditionally return an error, or simply return a static data using Mockaroo's Ruby API.

Step 3: Fetch Data

Start sending requests using the client library of your choice. Here's an example using JavaScript:

const url = 'https://my.api.mockaroo.com/users.json'

const users = await fetch(url, { 
  headers: {
    "X-API-Key": mockarooApiKey
  } 
}).then(response => response.json())

console.log(users)
