Create a funding source for an account

This section details how to add a bank account to your main Dwolla Account. To add a bank account as a Funding Source, you provide the account number and a routing number along with the Treasury Account in relation to which you want to attach the bank account. Funding Sources are relational to a main Dwolla Account and have the ability to send and receive funds.

​
Treasury Accounts

A treasury account is a prerequisite to sending and receiving ACH transfers. It also identifies your business so Dwolla can connect with your banking partner. To learn how to create a treasury acccount, contact us.
In Dwolla’s Sandbox environment, your test account will be pre-configured with a fake Treasury Account and Funding Source (Bank Account) associated with that Treasury Account. Using the pre-configured Funding Source for sending and/or receiving ACH transfers is intended to reduce the time and effort required to get started integrating with the Dwolla Connect API. You can retrieve the Funding Source ID associated with the fake bank account by listing your account’s funding sources.
