What is Event-Driven Architecture?

iPaaS & Integration

Event-Driven Architecture

An integration design pattern where systems communicate by publishing and subscribing to events — discrete notifications that something occurred (e.g., 'order placed', 'inventory updated'). Event-driven architectures enable real-time, loosely coupled integrations.

Why Event-Driven Architecture matters in B2B integration

Event-Driven Architecture is part of the ipaas & integration 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 Event-Driven Architecture touches your stack, we can help you connect it without custom code.

Talk to an integration architect

APIApplication Programming Interface

A defined set of protocols that allow software applications to communicate with each other. APIs are the foundation of modern integration — enabling ecommerce platforms, ERPs, marketplaces, and logistics systems to exchange data in real time.

API Gateway

A managed service that acts as the controlled entry point for API traffic, handling authentication, rate limiting, request routing, and monitoring. API gateways are critical infrastructure for organizations exposing or consuming APIs at scale.

Async Integration

An integration pattern where data is exchanged without requiring both systems to be available simultaneously. Events are queued and processed when the receiving system is ready — making async patterns more resilient than synchronous real-time calls.

Connector

A pre-built integration component that handles the technical details of communicating with a specific application — including authentication, data mapping, and API call construction. Quality connectors dramatically reduce integration build time and maintenance burden.

Data Mapping

The process of defining how data fields in one system correspond to fields in another. Accurate data mapping is the most critical — and most error-prone — step in any integration project. Mismatches in data types, field names, and business logic account for the majority of integration failures.

Data Transformation

Converting data from one format, structure, or schema to another as part of an integration workflow. Transformations include field renaming, data type conversion, currency normalization, and conditional logic.
