Introduction

This POS API provides a mechanism for you to integrate your physical terminals into the Merchant Warrior platform and create a unified payments experience (eCommerce and Card Present) for your organization.
You will be able to use this API to create transactions from your POS system and have your physical terminals process the transactions in real-time.
Prior to being able to use this API you will need to link your physical terminal(s) to your account via the administration portal. You will be provided with instructions on how to do this during your onboarding.
