ACH pull into Bakkt checking

You can now initiate an ACH debit from a user’s linked external bank account into their Bakkt checking balance for a given checking account.

• Use case: Move funds from the customer’s linked bank into Bakkt checking (for example, funding before other money movement).
• How to call: Use the new POST operation for ACH pull on the Bakkt account path in the API reference (the path includes the Bakkt account_uuid).
• Request: Send the amount and currency as described in the OpenAPI request schema; use the same authentication and session headers required elsewhere on the Accounts API.

Use the Accounts API OpenAPI definition for the exact path, request and response shapes, and status codes.
