How to integrate Email Hippo Assess into a decision engine
Connect Email Hippo Assess to a decision engine, step by step. This guide covers API key setup and explains how to create the data source in Decisimo and add the call to your decision flow so email, IP, and optional identity fields are evaluated during sign-up.
Email Hippo provides a service for verifying and profiling email addresses. It can be used to evaluate users during sign-up, which helps prevent garbage registrations and fraud down the road. Its services also include an IP address input, which helps prevent bot-driven registrations.
First name and last name are optional inputs. Because they are sensitive PIIs, you should decide whether to share customer data with another provider at that depth according to your data protection standards.
