As a transaction passes through the Automated Clearing House, it can be returned for a variety of reasons.
With nearly 80 ACH return codes, we’ve compiled a list with associated descriptions to reference that explains the return code.
A benefit of Dwolla’s API is automating the processing and notification of payment returns and corrections for businesses. At Dwolla, we help businesses navigate the ACH network to avoid the headaches of managing this process.

Dwolla helps businesses avoid ACH returns by requiring a sending customer to verify its bank information is entered correctly before initiating a transaction.
In addition, Dwolla offers customers the ability to test how their tech stack handles a failure, should an ACH return occur.
