This API is used to get the Threat Matrix data (Feature: Decision Manager : Device Fingerprinting).
It is now possible for SuiteCommerce Advanced sites, with checkout built custom or using reference checkout, to get the Threat Matrix HTML .
This API will only work for accounts with the Decision Manager : Device Fingerprinting (threatmetrix) enabled.
The Site Builder checkout would put additional HTML onto the page that is displayed after credit card data is accepted, but right before the order is submitted into NetSuite, which does the credit card authorization, and saves the order.
It will return this HTML block.
