Confirm that a bearer token is valid and see who it acts as: the user, their company, the company's theme and white-label branding and, for account tokens, the assigned plan.

Make this your first call after you get a token, and use it again whenever you need to confirm a token still works before a batch of requests. A 401 means the token is missing, expired or revoked.

Prerequisites: a bearer token. A token only works on the environment that issued it.

Authentication: Partner or Account token. The response always describes the token's own user and company; there is nothing to scope and no id to pass.

Rate limit: none.
