Getting Started with Payments
-
3D Secure
A cardholder authentication protocol that aims to reduce fraud and enhance security in eCommerce. The ‘D’ in ‘3D’ refers to the ‘three domains’: the merchant/acquirer domain, the issuer domain and the interoperability domain.
-
3DS Requestor
A 3Ds requestor is the party that initiates the 3-D Secure 2.0 authentication request to confirm that an account is still available or to verify a cardholder. For instance, the requestor could be a retailer or a digital wallet requesting authentication during the purchase flow.
-
3DS SDK / Mobile SDK
Embedded software within a merchant's mobile app that facilitates cardholder authentication. When a cardholder initiates an in-app (mobile) transaction, the 3DS SDK notifies the 3DS Core Components to verify the cardholder.
-
3DS Server
A 3Ds server provides the functional link between the DS and 3DS Requestor Environment flows. It is accountable for collecting the required data elements for 3-D Secure messages, authenticating the DS, validating the DS, the 3DS SDK, and the 3DS Requestor, as well as protecting the message contents.
-
Access Control Server (ACS)
The issuer domain (banks) of 3-D Secure includes the Access Control Server (ACS). Each card issuer is required to maintain an ACS utilised for supporting cardholder authentication.
-
Account Updater
A service that enables merchants to automatically update stored card details of their shoppers. Keeping this data up-to-date may be critical for accepting recurring payments.Account Updater works by providing information to the acquirer about lost and stolen cards, non-activated cards, and closed card accounts. Visa and Mastercard provide their separate Account Updater solutions.
-
Acquirer (or Acquiring bank)
A bank or financial institution that processes credit or debit card payments on behalf of a merchant. The acquirer allows merchants to accept card payments from card-issuing banks. To accept card payments, an acquirer should be licensed by corresponding card networks and either partner with a payment processor, or be a payment processor itself.
-
Acquirer Agreement
An agreement between an ISV, ISO, or payment facilitator and the acquirer that sells processing services. This contract is negotiated and determines a variety of topics including but not limited to: processing rates, transaction fees, value added services, liability, and applicable service level agreements (SLAs).
-
Acquirer Reference Number (ARN)
In credit card transactions, the Acquirer Reference Number (ARN) is a unique number assigned to a transaction when it goes from the merchant's bank (acquirer) through the card scheme at the cardholder's bank (issuer).The ARN can be used to track a payment or refund. Shoppers can contact their banks to do so and the banks can then use the ARN to track the payment or refund. Merchants can retrieve the ARN from the Customer Area or the shopper's bank.
-
Address Verification Fees (AVF)
Fees charged for the verification of a credit cardholder's address. This is typically performed via the Address Verification System (AVS), which verifies that the zip code submitted at the time of processing matches the zip code on the cardholder's billing statement.
-
Address Verification Service (AVS)
A tool that verifies the cardholder’s billing address (the zip code) in order to help combat fraud in card not present card payment environment (available mainly in the US and UK).
-
Aggregator merchant
Aggregator merchants are intermediaries between merchants and an acquirer. They are contracted by an acquirer to perform all or some of the following actions on behalf of the acquirer:
- Onboard merchants.
- Process transactions under an aggregated identifier. In this case, the merchant interacts with the aggregator instead of the acquirer.
- Settle transactions and ensure payouts to the merchants.
The following are types of aggregators:
- Bill payment providers
- Digital Wallet operators
- Marketplaces
- Payment facilitators -
Alternative Payment Method (APM)
Alternative payment methods can be categorised as any form of payment which isn’t cash, or a credit card issued by a major bank. Mobile payments, digital wallets, bank transfers, Buy Now Pay Later and prepaid cards are all examples of frequently used APMs. Also known as a local payment method.

Anti-Money Laundering (AML)
Anti-Money Laundering activities and controls are practices and procedures designed to identify and protect against financial criminals seeking to disguise illicitly gained funds as legitimate. Many institutions, especially those in the financial sectors, are required by the Bank Secrecy Act (BSA) to have detailed programs in place to prevent, detect, and report potential money laundering activities.
-
Application Programming Interface (API)
API stands for Application Programming Interface. This is a general term for programming techniques that are available for software developers when they integrate with a particular service or application. These techniques vary on the software type and may include web API, remote API, SDKs, libraries, frameworks, and much more. In the payments industry, APIs are usually provided by any party participating in the money flow (e.g. payment gateways, processors, service providers) to facilitate the money transferring process.
-
Arbitration
The procedure a member can initiate to resolve a chargeback-related dispute between two members.
-
Authentication
Authentication is the process of verifying a user or device before allowing access to a system or resources. In other words, authentication means confirming that a user is who they say they are. This ensures only those with authorized credentials gain access to secure systems. When a user attempts to access information on a network, they must provide secret credentials to prove their identity. Authentication allows you to grant access to the right user at the right time with confidence. But this doesn’t occur in isolation.
-
Authorization code
A code that an issuer provides to indicate approval of a transaction. The code is returned in the authorisation response message and is usually recorded on the transaction receipt as proof of authorisation.
-
Authorization fee
Technically called an authorisation request fee, this is what is charged each time a transaction is sent to the issuer to be authorised. The fee applies whether or not the request is approved. Note that this is not the same as a transaction fee.
-
Authorization
This is the process of the card issuer (like Visa or Mastercard) verifying payment details and reserving the funds to capture it later .In ecommerce, in-app and point-of-sale payments, authorisation is implemented as an API call to the payment gateway. The gateway and payment processor then perform required validation and risk checks, and ask a corresponding card network to authorise this payment from an issuer to an acquirer. When a payment was authorised but hasn't been captured yet, a merchant can also decide to cancel it for some reason (like a high risk of fraud). Note that authorisation is valid only for a limited amount of time. In case an authorised payment hasn't been captured or cancelled, it expires after the predefined deadline is missed.
-
Automated Clearing House (ACH)

Cancel a payment
An authorised payment can be either captured (where funds are sent to a merchant's account) or cancelled (where a merchant decides to reject the payment for some reason like a high risk of fraud).Note that cancelling a payment is not possible for transactions that have already been captured. In this case the merchant should initiate a refund to send funds back to a shopper. Captures, cancels, and refunds together are called modifications, because they modify the state of an authorised payment request.
-
Capture (or Clearing and settlement)
A payment that has been authorised by the payment processor must be captured to be completed. Capturing is the act of transferring the reserved funds from the shopper to the merchant. By default, payments are captured automatically, immediately after authorisation. Many payment methods support separate authorisation and capture. This means you can set up a capture delay; capture payments manually (both in the Customer Area and using API calls); perform partial captures; or cancel an authorisation. Captures, cancels, and refunds together are called modifications, because they modify the state of an authorised payment request.
-
Card issuer

Examples of some popular card networks are Visa, Mastercard, American Express, and UnionPay.Card schemes charge fees for processing payments, and also regulate the value of the interchange fee, which depends on many factors for each specific payment.
-
Card not present (CNP) transaction
A payment card transaction made where the cardholder does not or cannot physically present the card for a merchant's visual examination at the time that an order is given, and payment effected. It's mostly used for online payments, but also mail-order or telephone-order transactions.
-
Card number (PAN)
Every payment card (be it a debit, credit, gift, or a similar card) has a unique number associated with it. This number is usually printed on the card and required to uniquely identify this card and to refer to it in every transaction.The whole card number is called Primary Account Number (PAN), and the first six or eight digits of it are also called the Bank Identification Number (BIN).Also, a card may contain a card security code, which, along with the card number, can be used in card-not-present transactions.

Sometimes cards may be linked to ewallets or other local payment methods, but most commonly they are used to withdraw cash or make cashless payments.A typical card contains a card number, which uniquely identifies a card. It also contains a security code, used in combination with other information (a card expiry date and cardholder name) to verify card-not-present payments (for example, when paying for goods or services on a ecommerce website or inside a mobile application).
-
Chargeback
Chargeback refers to the return of funds used to make a purchase, initiated by the bank or financial institution that issued the funds. If a chargeback occurs, the cardholder's bank will be held responsible. An excessive number of chargebacks can result in issues with card networks who may refuse to onboard merchants on their networks. A chargeback occurs when a customer initiates the reversal of a payment transaction made with a credit or debit card. Customers typically request a chargeback if they believe the payment was erroneous, fraudulent, or if they encounter issues with the product or service they purchased, such as problems with its specifications, quality, or delivery. This process is facilitated through the customer's bank or credit card company, and the payment amount is refunded from the customer's account. While chargebacks are designed to safeguard consumers' rights and address their concerns, they can result in financial losses for sellers and harm their reputation.

Payment gateway
A payment gateway is the technology that securely transmits payment data between all the parties involved in the transaction flow. It operates as an encrypted and secure channel which passes the consumer’s payment details from the transaction device to the acquiring bank for authorisation and approval. Once approval has been granted from both the issuer and the acquirer, the payment gateway sends back verification to the merchant. Read our comprehensive explanation of payment gateways and how they work here. It is a service that helps merchants to initiate online, in-app and in-person payments. It is not directly involved in the money flow; typically, it is a web server to which a merchant's website or a POS system is connected. A payment gateway can be provided by a bank, or can exist as a separate service that connects to one or more payment processors. When a consumer uses a credit or debit card, the payment gateway securely transmits the data to the payment processor for transaction authorisation, ensuring that the information provided is sufficient to complete the payment.
