Getting started

Plain is an API-first customer service platform for modern companies.

We want to bring engineering and customer service teams together by creating a modern opinionated platform that's built to be built with.

We are currently in early access and you can sign up to our waitlist at

What does API first mean?

Being built API-first is a key principle of Plain. It means:

  • That we will always use the same API to build Plain that you you have access to. This means that you will never be given a simplified API or be restricted in what you can and can't do programatically via Plain

  • That we consider API users of new features on the same level as user of our Support App. This means we will avoid building features which overly rely on logic at the UI layer.

Where should I start?

First we recommend you familiarise yourself with our data model. This will help you orient yourself in the rest of the docs.

After that, head on over to make your first API call!

If you have any feedback on our docs we'd love to hear it! You can drop us an email at
