Account Session 

An AccountSession allows a Connect platform to grant access to a connected account in Connect embedded components.

We recommend that you create an AccountSession each time you need to display an embedded component to your user. Do not save AccountSessions to your database as they expire relatively quickly, and cannot be used more than once.

Application Fees 

When you collect a transaction fee on top of a charge made for your user (using Connect), an Application Fee object is created in your account. You can list, retrieve, and refund application fees.

Application Fee Refunds 

Application Fee Refund objects allow you to refund an application fee that has previously been created but not yet refunded. Funds will be refunded to the Stripe account from which the fee was originally collected.
