Perform validation

Introduction

Perform validation is initiated through HTTPS POST request by using URLs and the parameters.

Connecting Party’s app sends cardholder, device, session data and other parameters straight to Billblend to check the card for being valid.

A lot of criteria checks and filters may be applied, such as BIN, currency, country, blacklisted or not, etc. Depending on the integration, these settings may be customizable.
