How Hook2Flow Works

Here’s the basic flow of what’s happening behind the scenes:

1. Webhook event dispatched
   Your Shopify store triggers a webhook event (carts/update, variants/out_of_stock).

2. Hook2Flow listeners
   Hook2Flow listens for configured active webhook, then captures its content.

3. Payload parsed
   The webhook’s event content is read and saved in the appropriate webhook history.

4. Trigger Exposed to Shopify Flow
   Hook2Flow feeds that event into Shopify Flow.

5. Shopify Flow Executes Workflow
   Shopify Flow runs all the workflows that have such webhook as triggers.

This process lets you treat every webhook event as a true Flow trigger.
