Mass payments
Dwolla mass payments allows you to easily send up to 5,000 payments in one API request. The payments are funded from a single user’s specified funding source and processed asynchronously upon submission.Dwolla Mass Payments are meant for batches of multiple payments. If you are initiating a single payment to a singular Customer, we recommend using our transfers endpoint.
item is processed one after the other, at a rate between 0.5 sec. - 1 sec. / item. Therefore, you can expect a 1000-item mass payment to be completed between 8-16 minutes.
A mass payment offers a significant advantage over repeatedly calling the Transfers endpoint for each individual transaction. A key benefit is that a bank-funded mass payment only incurs a single ACH debit from the bank account to fund the entire batch of payments. The alternative approach will incur an ACH debit from the bank funding source for each individual payment. Those who used this approach have reported incurring fees from their financial institutions for excessive ACH transactions.
