Event-Driven Architecture
Event-driven architecture is a design approach where services communicate by producing and consuming events, such as order placed or subscription canceled, rather than calling each other synchronously. Consumers react to events independently, which decouples systems and improves resilience.
Technical Architecture & Deep-Dive
In event-driven systems, producers publish events to a broker or deliver them through webhooks, and any number of consumers subscribe. A payment event might update a database, send an email, and refresh a CRM record in parallel without the payment service knowing about any of them.
SaaS integrations are inherently event-driven through webhooks. Edge endpoints receive these events globally, verify signatures, and fan them out to downstream APIs, combining the reliability of events with the speed of edge execution.

Frequently Asked Questions
Q:Are webhooks part of event-driven architecture?
Yes. Webhooks are a common way for external SaaS platforms to publish events to your systems over HTTP.
Related Architecture Concepts
A webhook is an HTTP callback: when an event occurs in one system, it sends an HTTP POST with event data to a URL you register. Instead of polling an API repeatedly for changes, your application receives updates in real time, such as payment succeeded or ticket created events.
API orchestration is the coordination of multiple API calls in a defined sequence, where outputs from one step feed inputs to the next. An orchestrator manages ordering, dependencies, error handling, and the final response, so clients trigger a multi-step workflow with a single request.
Idempotency means that performing the same API operation multiple times has the same effect as performing it once. Idempotent endpoints let clients and gateways safely retry requests after timeouts without creating duplicate orders, charges, or records.
Ready-to-Use Edge Recipes
To solve how to combine multiple rest webhooks into one payload, never execute unauthenticated requests or embed private tokens directly in client bundles. RealComposer acts as a sub-10ms edge gateway running on Cloudflare Workers that securely injects credentials from your Secret Vault, normalizes responses, and prevents unauthorized API usage. Route calls through your RealComposer edge URL to guarantee complete privacy, robust origin validation, and low mobile latency.
Any Frontend / Mobile apps hit CORS and credential limits when calling Paddle and Supabase. Edge receives Paddle webhook and updates Supabase in one flow. Use one RealComposer edge URL with OPTIONS handling, client tokens, and vault injection.
