API and webhooks
Your systems talk to POSfix directly.
Your online shop, ERP or accounting software reads and writes the company’s catalog, stock, prices, customers, orders and sales through the API. The POSfix team issues the key, and the full reference, with the Postman collection, is on docs.posfix.md.


Features
What your system can do.
Catalog, stock and prices
Products with their categories, attributes and translations, the stock in every warehouse and the company’s price lists.
Orders from your online shop
An order sent through the API enters POSfix as a customer order and reserves the goods. Sent twice, it isn’t duplicated.
Sales by day and channel
The Z reports from the till and all sales by day and channel — the same figures you see on the “Sales” screen.
Customers and loyalty
You create and look up customers, and with the loyalty module you read members and their balances and grant bonus per order.
Recognized invoices
You send the supplier’s invoice, as a PDF or a photo, and get back the supplier, the totals and its lines.
The till has an API too
An ERP or a sales program issues fiscal receipts through the POSfix till, on Windows or Android, from the local network or remotely.
Webhooks
Your system learns what has changed.
The platform notifies your address when a product, a stock level, an order, a sale or a recognized invoice is created or changes. Every delivery is signed, and in the panel you see what was sent and what you answered.
- Events for products, stock, orders, sales, invoices and loyalty
- A failed delivery is retried by itself, at growing intervals
- The log in the panel keeps the last 30 days
- You resend a delivery once you’ve fixed your system
