PATCH /bank-details/{bank_details_id}

Update one bank account

Updates one bank account. A field you omit keeps its stored value. Send null to clear a field that can be empty. An empty body changes nothing. This route does not change the debit account. Call set-primary to choose the debit account. The response shows the last four characters of the account number and the routing number. An Owner or Admin can call this route, and an API key can too. The organization is selected by Organization-Id, Connection-Id, or Entity-Id.
