Integrations

Shopify Flow, outbound webhooks, the REST API, Sidekick, the AI connector, and what the web pixel does.

Ways to get Notifylyst events and data out of the app, in rising order of effort.

Integration	Reach for it when
Shopify Flow	You want automation inside Shopify with no code at all.
Webhooks	You want events in n8n, Zapier or Make.
REST API	You are building something yourself.
Sidekick	You want to ask Shopify’s assistant about waiting demand, inside your admin.
AI connector (MCP)	You want Claude or another AI tool to read — and, with your confirmation, change — your Notifylyst data.

​

Shopify Flow

Notifylyst adds three Flow triggers. In Flow, start a new workflow, choose Select trigger, then pick CB Notifylyst.

Trigger	Fires when	Data you can use
New subscriber	A shopper signs up for an alert.	Product, Email, Channel, Phone, Product title, Variant title, SKU, Requested quantity, Form answers
Notification sent	A restock alert goes out on any channel.	Product, Channel, Recipient, Product title, Variant title, Campaign step, Requested quantity
Converted purchase	A shopper buys after an alert.	Product, Order, Channel, Conversion type (direct or assist), Product title, Variant title, Customer email, Customer phone, Revenue, Quantity

Notifylyst has no Flow actions — only triggers.

Ideas: tag customers who keep waiting for a sold-out line; post to Slack when a high-value product converts; add shoppers who converted to a segment.

​

Webhooks

Settings → Webhooks sends events to n8n, Zapier, Make or your own endpoint the moment they happen.

Event	Meaning
subscriber.created	New subscriber — someone requested a back-in-stock alert.
notification.sent	Notification sent — a restock alert was sent.
notification.converted	Converted (purchase) — a subscriber bought after being notified.

1. Press Add endpoint, give it a Name and a Destination URL, and pick its events.
2. New endpoints start off: use Send test to check your receiver, then switch it on.
3. Recent deliveries shows each delivery with its HTTP status, attempt and time.

The URL must use HTTPS, point to a public address and contain no username or password; otherwise you see URL must use HTTPS., URL must point to a public internet address. or URL must not contain credentials.

The number of endpoints depends on your plan (Endpoints: X of Y used). At the limit, Add endpoint becomes an upgrade button: Your plan includes N webhook endpoints. Upgrade to add more, or remove one first.

Pick Flow or webhooks for a job, not both. Two systems reacting to the same sign-up is the usual cause of a shopper getting two of everything.

​

REST API

Settings → API key gives you a key to read your sign-up and notification data from your own systems — a dashboard, a warehouse system, a data warehouse. API documentation opens the reference.

• The full key (starting nl_live_) is shown once, when it’s created. Lost it? Regenerate key: the new key replaces the old one, which stops working straight away.
• Revoke key switches API access off until you create a new key.
• Send the key in the X-API-Key header, for example to https://api.notifylyst.com/v1/data.
• Requests are rate-limited by plan. Over the limit you get HTTP 429; the X-RateLimit-Limit header shows your limit.

Treat the key like a password: never put it in front-end code or a shared document.

​

Sidekick

Notifylyst works with Shopify’s Sidekick assistant in your admin. Sidekick can:

• answer questions about waiting demand — which products to restock first, who is waiting for a product, and your Notifylyst settings;
• prepare changes to your alert channels, report emails and restock rule. It opens Settings with the change filled in — you review it and press Save.

​

AI connector (MCP)

Connect Claude or another AI tool and ask in plain language — “which products are people waiting for that I already have stock of?” — with your confirmation needed before anything changes.

​

The web pixel

Notifylyst installs a Shopify web pixel. It does one thing: when a shopper arrives from an alert link and then completes checkout, it tells Notifylyst, so the order counts as Direct. It doesn’t track other browsing or widget use. Nothing to configure.
