- AI suggests, people decide
Isolated tools mean double maintenance.
When inventory, shop, ERP and reporting do not talk to each other, data is maintained several times and never quite matches.
Standard interfaces.
The REST API gives access to items, stock, prices and sales. Webhooks report events such as “sold” or “revalued” the moment they happen.
How it works
- Set up access for your system
- Read and write data through the REST API
- Subscribe to the webhook events you need
- Connect ERP, shop or reporting
What you get
Documented interface
Described in OpenAPI format. Your team can see in advance which data it can read and write.
Events in real time
Webhooks instead of constant polling. Your system learns at once when something changes.
Same permissions as the app
Access only to shared data. Each access sees only what you share.
