# Introduction ## Overview All programmatic interaction with our REST API is done using a logged-in Service Account. Once the client has been authenticated, the program interacting with the API will be able to perform operations as an administrator of the organization. ## Service Account vs User Account There are two types of accounts available; the user and the service account. A user account represents a person, and requires an email and authentication that is suited for user authentication (password or *SSO* using *SAML*). A Service Account represents a program, and the authentication scheme is optimized for machine to machine authentication using key-secret pairs that can be rotated if needed. The service account is bound to a single organization, while a user account can be bound to multiple organizations. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
