Introduction #

Welcome to the Dwolla Connect API documentation! Dwolla Connect is a modern RESTful API solution that allows businesses to integrate account-to-account payment processing into their applications using their existing commercial bank accounts. Implementing and maintaining Dwolla’s unified API across financial institutions and payment modalities can save businesses a significant amount of development time and resources, unlock the ability to automate manual processes and increase visibility into payment activity. This API provides a comprehensive set of resources and endpoints for managing users, adding payment accounts, initiating transfers, and querying transaction history.
