Getting started

Getting started

The shortest path from an API key to a working domain connection flow.

You need a Domain0 application, a server API key, and a page where your user can complete DNS setup.

Install the package

Add domain0 to a TypeScript or JavaScript application.

Build the flow

Create a connection and open the browser dialog.

Understand the boundary

See how keys, tokens, states, and DNS verification fit together.

Before you begin

  1. Create an application in the Domain0 dashboard.
  2. Create an API key for that application.
  3. Copy the key when it is shown. Domain0 does not show the raw value again.
  4. Add the key only to your server environment.
DOMAIN0_API_KEY=d0_replace_me

Never prefix this variable with NEXT_PUBLIC_, VITE_, or any other mechanism that bundles environment values into browser code.

Domain connections, without the closed box

Connect customer domains through a type-safe SDK and an embeddable setup flow.

Installation

Install the Domain0 package for TypeScript or JavaScript.
