Current edition: Shopify Flow

External events into Shopify Flow

Set up FlowRelay, send a safe test event, read the receipt, and know what to do when an event needs attention.

External events into Shopify Flow

Let a supplier, app, or back-office system start a Shopify Flow workflow through FlowRelay.

Recover a failed handoff

Use receipts, error codes, and replay controls when an event needs attention.

Work with a partner without sharing secrets

Share redacted evidence so a sender owner, partner, or FlowRelay support can help safely.

Let an agent investigate an event

Give an authorized agent enough context to inspect receipts and prepare governed recovery.

Start setup

01 Create an endpoint Create the sender-facing URL and choose the event type Shopify Flow should receive. 02 Authenticate requests Choose HMAC-SHA256 or static-header authentication without exposing secrets. 03 Event types and payloads Choose the Shopify Flow trigger variant and required JSON paths your sender can support. 04 Add the Shopify Flow trigger Enable the FlowRelay trigger that receives the event in Shopify Flow. 05 Send your first test event Send synthetic data and confirm one Delivered receipt.

Operate

Read receipts See what FlowRelay accepted and where the handoff stopped. Event history Find accepted, delivered, failed, replayed, and retained events without copying private data. Event lifecycle Understand accepted, queued, delivered, failed, no-workflow, duplicate, and replay states. Retention Know what FlowRelay keeps, when replay expires, and what remains as safe receipt evidence. Usage limits See how plan caps affect new intake and governed operations without hiding existing receipts. Rotate credentials Replace an exposed or stale endpoint secret without revealing the old value.

Recover

Error codes Start the stable recovery-code glossary. Retries, replay, and resend Separate sender retries, FlowRelay processing reconciliation, and deliberate replay. Replay an event Preview side effects before a recovery replay. Duplicates and idempotency Understand duplicate suppression and action idempotency before resending or replaying. Share diagnostics Send redacted evidence to support or a partner. Work with support Use receipts, diagnostics, and support-safe summaries when FlowRelay support needs evidence.

Agent Access

Agent Access Create scoped, revocable access for authorized agents without exposing broad store authority. Grants and scopes Compare authority tiers, expiration choices, revocation, audit, and hard boundaries. Agent orientation Give authorized agents the right docs, Markdown pages, OpenAPI, CLI, and MCP entry points. Support and expansion requests Let scoped agents submit structured support and expansion requests without bypassing support safeguards.

Reference

Agent Operations API Use the canonical machine contract for scoped reads and governed action intents. CLI Use the terminal wrapper for docs discovery, doctor checks, JSON reads, and action previews. MCP Use the Code Mode MCP endpoint as a governed wrapper over the same Agent Operations contract. Action intents Describe preview, confirmation, idempotency, and audit structure. OpenAPI Expose schema and machine-readable contract locations.
