About the API
Connected Accounts

If you use Stripe Connect, you can issue requests on behalf of your connected accounts. To act as a connected account, include a Stripe-Account header containing the connected account ID, which typically starts with the acct_ prefix.

The connected account ID is set per-request. Methods on the returned object reuse the same account ID.
