# Talkdesk OAuth, account or user

Study notes. Not vendor documentation and not legal advice.

- The authentication page says Talkdesk supports OAuth 2.0.
- Client Credentials are for account-level access, on behalf of an entire Talkdesk account.
- Authorization Code is for user-level access, on behalf of a single user.
- The page's front matter shows updatedAt 2026-09-10.
- Client secrets do not belong in this lab.

An integration uploads schedules for the whole account. Write Client Credentials and the reason: account-level access. An app that acts as one supervisor writes Authorization Code. Write the doc date you saw, 2026-09-10, as the page's updatedAt, not as a product release.
