Sift Science Integration

As part of Dwolla’s Access API, Partners can choose to implement Sift Science’s machine learning model for real-time ACH fraud monitoring.

The need to leverage machine learning in protecting against fraud becomes increasingly valuable as payment volume scales. With this in mind, many Access API Partners look for the right solution to help manage risk for their ACH payments.

Often, we see Partners choosing to use Sift Science in order to better monitor and protect against fraud. We understand the value Sift’s real-time risk scoring model can provide our Partners, so we’ve integrated the service right into the Access API.

In this article we’ll cover the steps to get your Sift Account set up, as well as the process for integrating Sift into your Access API Dashboard.

Integration overview

Animation of Sift Science Integration

It is important to note that your integration with Sift will involve the placement of Sift Science JavaScript within your application. Dwolla is unable to perform this code placement on your behalf, as the Sift Science JavaScript implementation occurs within your application.

As outlined in the bullet points above, first you’ll insert your Sift Science JavaScript within your application. Subsequently, you will copy and paste your Sift Science API key within the Integrations section under Account in the Access API Dashboard. Then you are all set!

The events below are sent to Sift on your behalf by Dwolla’s API, and there is no additional development needed on your side. Events will begin populating into Sift once your integration is complete.
