Use Cases

External events into Shopify Flow

Use this path when the important event starts outside Shopify but the workflow should stay inside Shopify Flow.

Open the practical guide Read Create an endpoint.

When to use this #

Use FlowRelay when Shopify Flow is the right workflow system, but the event source is not a native Shopify trigger.

What FlowRelay owns #

FlowRelay owns intake, authentication, validation, receipt history, and the handoff to Shopify Flow. Shopify Flow owns workflow branches and downstream actions.

What to avoid #

Do not paste real event bodies, customer data, endpoint secrets, authentication headers, or copied incidents into examples. Use synthetic values while proving the setup.

Typical path

A typical path starts from the scenario, then moves into setup and verification.

  1. Identify the outside system that will send the event, such as a supplier portal, warehouse tool, ERP, custom app, or partner system.

  2. Create a FlowRelay endpoint for that sender and choose the event type Shopify Flow should receive.

  3. Configure HMAC-SHA256 or static-header authentication with the sender owner.

  4. Add the matching FlowRelay trigger to the Shopify Flow workflow.

  5. Send one test event with synthetic data, then use the FlowRelay receipt to confirm the trigger was handed to Shopify Flow.

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.
