Create an Application

When integrating with our API or authentication system, you’ll first need to register an application (more accurately an OAuth Client). This registration process creates the credentials that identify your app — specifically, a Client ID (and sometimes a Client Secret dependencing on your application type) — that enable OAuth-based authentication and authorization.

What is a Client ID?

A Client ID is a unique identifier issued to your application when it’s registered with the authorization server. It represents your app in the OAuth terminology — much like a username for your app.

• It’s publicly visible (e.g., in API requests, JavaScript code, or redirects).

• It helps the authorization server recognize which app is making a request.

• It’s paired with a Client Secret for confidential applications to authenticate securely.

Think of it as the way the system knows, “This request is coming from your app.”

Select your Application Type

When registering your app, make sure to select the application type that best matches your environment and security model — see the Application Types section for guidance on which option to choose.

Scopes

Scopes define what your application can access on behalf of a user or service. When creating or editing your Client ID, you’ll need to choose the scopes your app requires.

1. Identify your app’s needs — what data or actions does it require?

2. Select only the necessary scopes — this limits access and improves security.

3. Add the scopes to your OAuth request — e.g. scope=account user-data.

4. Review the consent screen — users will see and approve the scopes you request.
