Dwolla allows anyone connected to the Internet to safely send and receive money. Dwolla's API enables developers to easily integrate money functionality into their applications, moving funds around in a RESTful breeze.
Dwolla
Using Dwolla's API starts with creating an application that's tied to a Dwolla account. Once set up, whether sending once-in-a-while payments or fully integrating with a specialized point of sale system, your Dwolla application will act as your identity to the end user & as a central point to graphically manage your application settings.
Dwolla's API can be integrated in 3 different flavors:
- Simple payment button. Read about creating a button »
- Offsite checkout gateway. Read about the offsite gateway »
- OAuth + RESTful API. Read about the API »
