Setup

Add the Shopify Flow trigger

Shopify Flow owns the workflow logic. FlowRelay owns the reliable handoff into the matching trigger.

Next step Continue with Send your first test event.

Steps

Complete these in order.

  1. 01Open Shopify Admin, open Shopify Flow, and create a workflow for the event you want to receive.
  2. 02Choose the FlowRelay trigger that matches the endpoint event type.
  3. 03Add conditions and actions that are safe for a synthetic test, avoiding customer emails, fulfillment changes, and production mutations.
  4. 04Save and enable the workflow in Shopify Flow.
  5. 05Return to FlowRelay, send one synthetic test event, and open the receipt to confirm the handoff.

Match the trigger #

The Shopify Flow workflow must use the FlowRelay trigger that matches the endpoint event type. A mismatch can produce an accepted FlowRelay event with no enabled workflow handoff.

Keep the first workflow safe #

For the first proof, use conditions and actions that are safe with synthetic data. Avoid customer emails, fulfillment changes, inventory mutations, and production side effects until the receipt confirms the handoff.

Success check #

A Delivered receipt confirms FlowRelay handed the trigger to Shopify Flow. To confirm branches or downstream actions, inspect Shopify Flow run behavior separately.

If Shopify Flow does not run #

Check that the workflow is enabled, the trigger variant matches the endpoint, required identifiers are mapped, and the test data satisfies Shopify Flow conditions.

Handoff boundary

Delivered means FlowRelay handed the trigger to Shopify Flow. It does not mean downstream Shopify Flow branches, app calls, fulfillment changes, emails, or later systems completed.
