# Mock API Server

Unified.to has a "mock server" that uses pre-generated synthentic data that emulates the data available in any of our integrations.

## [How to call the mock server](#how-to-call-the-mock-server)

You can call any REST API endpoint with a `X-Mock: 1` header. Make sure to have an empty `Authorization` header and use URL IDs and payload data that are properly formatted (e.g. ID=5de520f96e439b002043d8dc).

## [Sandbox environment](#sandbox-environment)

You can also use the "Sandbox" environment when making API calls as that will also use the Mock API Server.
