SCALE · API
Your store, connected to everything you run.
Your ERP knows the stock. Your warehouse packs the orders. Your accounts team needs the sales. The Shopnix API connects them all to your store, so nobody types the same order twice.

WHAT YOU CAN CONNECT
The software you already run, talking to your store

ONE KEY PER SYSTEM
Each connection gets only what it needs
Turn on API access in Shop Apps. Every staff user gets their own API key, so each system connects as its own user. On Mega Store, give that user only the permissions it needs: the warehouse app sees orders, not your revenue.
- A key for each staff user
- Regenerate a key at any time
- Permissions per user on Mega Store
WEBHOOKS
Your systems hear the moment something changes
No checking every five minutes. When an order is placed, paid, shipped or delivered, Shopnix can tell your system straight away. Shopnix already works this way with payment gateways and couriers: their updates arrive the moment they happen.
- New orders and payments
- Shipment updates
- Order status changes

Example with sample data.
RUNNING TODAY
One store's stock syncs every hour
A Shopnix store keeps its products and stock in its own inventory system. Every hour, the two sync. The website never sells what the warehouse doesn't have.

HOW TO START
From switch-on to first sync
Turn on API access
In Store Manager, under Shop Apps.
Get a key
Each staff user has their own.
Connect
Your developer uses the API docs, or our team builds it.
Let it run
Stock, prices and orders stay in step.
