Issue a token that acts as the account's owner. Use this before calling account-scoped endpoints on a customer's behalf. A token lasts 7 days. Repeat calls return the same token while it's still valid, for up to 6 days after it was issued; after that a new token is issued and the previous one is revoked (prior_tokens_revoked counts them). Returns a token. Use it as the Authorization header for the account-scoped calls.

Prerequisites: a Partner token, and the account's id (account_id) from List accounts. The account must have an owner.

Authentication: Partner token. Any other token gets 403. account_id must be an account inside your partner's tree, otherwise 403. The token acts as the account's owner.

Rate limit: 120 requests per minute, counted per user (the token’s user).
