Modular Workflows

Comparison of a single monolithic workflow with many interconnected nodes versus multiple modular workflows, each containing a simple linear chain of nodes

The Producer-Consumer Pattern

Workflow B (the consumer) with a Webhook Trigger node exposing an HTTPS URL and waiting for incoming requests

The Producer-Consumer Pattern

Workflow A uses an HTTP Request node to send a POST request to Workflow B's Webhook Trigger, connected by a dashed arrow

The Producer-Consumer Pattern

Workflow A highlighted in blue and labeled Producer, sending requests via HTTP to Workflow B's Webhook Trigger

The Producer-Consumer Pattern

Producer-consumer pattern: Workflow A (Producer, blue) sends data via HTTP to Workflow B (Consumer, red), which receives it through a Webhook Trigger

Summary

Producer-consumer pattern summary: Workflow A (Producer) connects to Workflow B (Consumer) via HTTP Request to Webhook Trigger

Let's practice!
