Step-by-Step Implementation Guide
3 StepsInitialize Trigger Event in Webflow
Configure your primary trigger event inside Webflow by adding required custom attributes or registering a project webhook.
Why we recommend Claude 3.5 Sonnet: It provides native support for structured JSON payloads and zero-latency parsing.
<form id='custom-trigger-form' data-workflow='webflow-ai-knowledge-base-claude'> <input type='text' name='query' required placeholder='Enter request...' /> <button type='submit'>Run Workflow</button> </form>
Connect Webhook Orchestration in Make.com
Set up a webhook listener to capture the inbound payload, parse key parameters, and dispatch an API request to the AI reasoning engine.
Why we use Make.com here: Zapier charges 3x more for JSON-nested Webflow webhooks and often times out on AI responses. Make.com's free tier handles this with 0 latency.

Always pass API tokens through backend webhooks or serverless proxies instead of writing keys directly in Webflow page settings.
