Use Zapier or Make as a bridge to 5,000+ apps. Any service they support becomes a Flow trigger — Salesforce, HubSpot, Notion, Airtable, whatever you've got.
Zapier and Make connect thousands of apps and are excellent at app-to-app automation, but neither can start a Shopify Flow workflow: every native Flow trigger is an internal Shopify event, and there's no built-in trigger that fires from an outside webhook. The two tools solve different halves of the problem.
The combination is the answer. Let Zapier (or Make) gather the event from Salesforce, HubSpot, Notion, or any of its 5,000+ apps, then add one Webhooks-by-Zapier POST to your Flow Plus channel. Map the fields onto Field1..Field8 (full payload in JSONString) and Shopify Flow runs the Shopify-side automation natively — using Flow as the free, native action engine instead of paying middleware to replace it.
Bridge any of Zapier's 5,000+ apps to Shopify Flow. Install, point a Webhooks-by-Zapier POST here, done.
Add the Webhooks-by-Zapier action to any Zap. Set the URL to your Flow Plus channel. Map up to 8 fields from the source app to Field1..Field8.
Salesforce lead created → Zapier → Flow Plus → Flow creates the Shopify customer and tags them as a B2B lead.
HubSpot deal moves to Won → Zapier → Flow Plus → Flow tags the matching Shopify customer and applies a wholesale price list.
Internal CMS row changes → Zapier → Flow Plus → Flow updates Shopify metafields, draft products, or fires admin notifications.
A channel gives you a unique signed URL ready to receive a Webhooks-by-Zapier POST from any Zap.
In Zapier, add a Webhooks-by-Zapier POST action with your Flow Plus channel URL, then map the source-app fields.
Use the Flow Plus trigger inside Shopify Flow — your fields appear as variables. Drop them anywhere you'd normally drop trigger data.
Install Flow Plus on Shopify, add a Webhooks-by-Zapier step, and you'll be triggering Flows from any Zap in minutes.
