Dwolla’s customers have a contracted responsibility to maintain at least a zero Dwolla balance for their customer records created through the API within their application. Should a customer record encounter a negative balance, Dwolla will send an email to the main email address on the contracted customer account with details around the user with the negative balance.  

At this time, Dwolla will also request that the platform customer bring the account to a zero balance. If no action is taken, Dwolla will debit the platform customer's billing source.

If you have additional questions around what a might have caused a negative balance or what you can do to prevent that from happening, please reach out to support@dwolla.com.
