Term	Explanation
Acquirer	An acquiring bank (or acquirer) is the bank or financial institution that processes credit and/or debit card payments for a merchant. Example: Barclays Merchant Service and European Merchant Services.
API	The API is a collection of tools that enables merchants to execute requests to the Skrill Payment Gateway. For example: to send money, make 1-Tap payments, make refunds, check the status of transactions, and download reports.
Back-end system	As opposed to a front-end system, a back-end system is used internally by Skrill or within the merchant's business. Skrill merchants can also use payment information returned from the Skrill Payment Platform on their own back-end systems, such as their customer order management system.
Batch	A group of approved credit card transactions, accumulated during one business day (weekends and official/bank holidays excluded).
Browser	Application that enables a customer or merchant to access web pages. Examples include: Internet Explorer, Google Chrome, and Mozilla Firefox.

MD5	A widely used hash algorithm, which can be used for securely encrypting information sent over the internet. MD5 produces a 128-bit (16-byte) hash value. The purpose of the field is to ensure the integrity of the data posted back to the merchant's server.
