**It's a wild west of data out there, where rules and best practices are shot from the hip. This makes injesting data cleanly a colossal pain in the ass. Flatfile is the missing API for data exchange, import, and migration.**

With Flatfile, you can:

* Accept, transform, and validate data so that it arrives in your systems in exactly the right shape
* Embed an easy-to-use, self-service data importer directly into your app
* Invite your customers to collaborate on a hosted onboarding project, replacing hours of back-and-forth communication

Let's design and build your dream data exchange experience.

### About our API

The Flatfile API uses [REST](http://www.drdobbs.com/web-development/restful-web-services-a-tutorial/240169069). Our API is designed to have predictable resource-oriented URLs and to use HTTP response codes to indicate API errors. It accepts form-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.

The Flatfile API doesn't have a test mode; however, [Environments](/api-reference/environments)  allow you to test without affecting your live data.

### Getting started

To begin working with Flatfile, follow this [link](https://platform.flatfile.com/account/sign-up) to sign up and immediately retrieve your API keys.
