What is Payment Gateway?

Ecommerce

Payment Gateway

A technology service that authorizes and processes payment transactions between buyers and sellers. Payment gateways handle encryption, fraud screening, and communication with card networks. Examples include Stripe, Braintree, and Authorize.Net.

Why Payment Gateway matters in B2B integration

Payment Gateway is part of the ecommerce vocabulary that operators, IT leaders, and integration architects use when scoping ecommerce, ERP, EDI, and fulfillment projects. APIWORX integrates 200+ systems across this landscape — if Payment Gateway touches your stack, we can help you connect it without custom code.

Abandoned Cart

A shopping session where a customer adds items to an online cart but leaves without completing the purchase. Abandoned cart recovery — through automated email sequences or retargeting — is one of the highest-ROI tactics in ecommerce. Industry averages show 70%+ cart abandonment rates.

Average Order ValueAOV

The average dollar amount spent per transaction on a given channel or store. AOV is a primary lever for revenue growth alongside conversion rate and traffic volume. Merchants improve AOV through bundling, upsells, and free-shipping thresholds.

B2B Ecommerce

The buying and selling of goods and services between businesses conducted through digital channels. B2B ecommerce typically involves complex pricing structures, account-based access, purchase order workflows, credit terms, and multi-user account management — all of which require tighter integration with ERP and OMS systems than standard B2C stores.

B2C Ecommerce

Business-to-consumer online retail, where brands sell directly to individual shoppers. B2C ecommerce prioritizes conversion rate optimization, customer acquisition cost, and lifetime value as core metrics.

Buy Box

The prominent "Add to Cart" section on marketplace product pages (notably Amazon) that routes the sale to a specific seller. Winning the Buy Box requires competitive pricing, strong fulfillment metrics, and seller health scores. It is the primary driver of marketplace revenue for most brands.

Catalog Management

The process of creating, organizing, and maintaining product data — including titles, descriptions, images, pricing, variants, and attributes — across one or more sales channels. Inconsistent catalog data is a leading cause of integration failures and poor conversion rates.
