Authentication

Choose the right authentication method for your Seam integration — API keys for server-side, client sessions for frontend apps, or personal access tokens for development.

Seam supports several authentication methods, each designed for a different use case. All methods authenticate against the Seam API at https://connect.getseam.com.

API Keys

Server-side authentication for production apps. Create API keys in Seam Console and pass them via the Authorization header or SDK constructor.

Personal Access Tokens

Authenticate as yourself across all your workspaces. Ideal for development, scripting, and the Seam CLI.

Client Session Tokens

Scoped tokens for frontend apps. Grant users access to specific devices without exposing your API key.

Choosing the Right Method

Method	Use case	Scope	Where to use
API Key	Production backend	Single workspace	Server-side only
Personal Access Token	Development and CLI	All your workspaces	Local dev, scripts
Client Session Token	Frontend apps	Scoped to specific devices	Browser, mobile

API keys and personal access tokens should never be exposed in client-side code. Use client session tokens for any frontend integration.
