Dwolla utilizes the OAuth 2 protocol to facilitate authorization. OAuth is an authorization framework that enables a third-party application to obtain access to protected resources (Transfers, Funding Sources, etc.) in the Dwolla API. The following guide will walk through Dwolla's implementation of OAuth and how it will be leveraged by your application.
Before you can get started with making OAuth requests, you’ll need to first register an application with Dwolla by logging in and navigating to the applications page in the Dashboard. Once an application is registered you will obtain your
client_secret (aka client credentials), which will be used to identify your application when calling the Dwolla API. The Sandbox environment provides you with a created application once you have signed up for an account. Learn more in our Sandbox guide.
The OAuth 2 protocol defines four main authorization grant types, more commonly referred to as OAuth flows. Dwolla implements one of these flows that third party applications will utilize to obtain authorization.
Application authorization: - Using the client credentials grant flow, your application will obtain authorization to interact with the API on its own behalf. This is a server-to-server flow with interaction between an application and the Dwolla API; also known as 2-legged OAuth.
All funds transfers made using the Dwolla Platform are performed by a financial institution partner, and any funds held in a Dwolla Balance are held by a financial institution partner. Learn more about our financial institution partners.
