Announcing Alliance One’s new API

We are pleased to announce that the Alliance One API (application programming interface) is live, and participant financial institutions can start taking advantage of it right away.

Experience the power of Alliance One

Managed by Corporate One, Alliance One is a nationwide cooperative group of credit unions, community banks and thrifts that have joined forces to let their cardholders access each others’ ATMs all over America without having to pay ATM surcharges. That cooperative spirit not only gives cardholders more convenient ATMs to choose from, it also leaves that extra money where it should be - in cardholders’ accounts.

What is the Alliance One API?

The Alliance One API offers read-only access to more than 5,000 ATMs and their information (financial institution, address, and features). Financial institutions can create an Alliance One ATM locator on your financial institution's website or mobile app. Alliance One ATMs can also be combined with any other ATM groups or networks your financial institution participates in, which makes it easier on cardholders to find and access ATMs.
