Merchant Evaluations

POST https://api.fraudio.com/v1/merchants/risk-evaluations

Endpoint Overview

Our Merchant Evaluations endpoint collects the outcomes of your investigations of merchants. These merchant evaluations are very important for the Merchant Fraud and AML product as they are used as labels and feedback mechanism to train and update our Machine Learning models.

Merchant evaluations are only applicable under the following circumstances:

• you are using the Merchant Fraud product and/or the AML product
• you have a risk team that evaluates merchant accounts

The merchant evaluations can be sent either individually or in batch.
