Organizations gives your app's customers teams. A **Customer Organization** is a tenant inside your app; a **Membership** places one of your end users in it with roles your app defines; an **Invitation** asks an email address to join, and accepting it creates the membership.

## Where it is served

Organizations is served by Sylphx Auth on the one API. Every call is
under `https://api.sylphx.com/v1/orgs/{org}/projects/{project}/envs/{env}/`
and takes a Sylphx key with the scope its method names in the API reference
([keys and scopes](/docs/platform/keys-and-scopes)).
