DocsStep 3: Retrieving Funding Sources #
Now that you’ve created a Customer and associated its funding source, you are close to being able to initiate your first transfer. The transfer requires the following information:
- A funding source to pull the funds from (your Customer’s linked bank funding source)
- A funding source to push the funds to (your Dwolla Master Account’s linked bank funding source)
Dwolla uses URLs to represent relations between resources. Therefore, you’ll need to provide the full URL of the funding source and recipient.
Step 3A: Retrieve your Customer’s list of available Funding Sources #
In order to find your Customer’s available bank and balance funding sources, you will need to first retrieve the funding sources from your Customer, via the API.

When the funding sources are successfully retrieved, you will receive a 200 HTTP response with the details of the funding sources. After retrieving the funding sources, we recommend storing the full URL for future use as it will be referenced when creating the transfer to this end user’s bank account.
