Connected Accounts 

About the API
Connected Accounts

To act as connected accounts, clients can issue requests using the Stripe-Account special header. Make sure that this header contains a Stripe account ID, which usually starts with the acct_ prefix.

The value is set per-request as shown in the adjacent code sample. Methods on the returned object reuse the same account ID.

Per-Request Account
import stripe
charge = stripe.Charge.retrieve(
"ch_3Lmjoz2eZvKYlo2C1rBER4Dk",
stripe_account="acct_1032D82eZvKYlo2C"
)
charge.capture() # Uses the same account.
