Create a Funding Source for an External Party #

This section details how to add a bank account to external parties. To add a bank account to an external party, you can use one of two methods:

Option 1: Provide the account number, routing number, type, and a nickname.
Option 2: Create an exchange for the external party, which will create a secure connection between Dwolla and a third-party provider for account creation and verification.

Funding Sources are relational to an External Party and have the ability to send and receive funds.
