Integration journey

From zero to live sync in four steps

Based on partner onboarding research: teams that follow a structured integration path ship 3× faster and reduce support tickets by 60%.

1

Discover

Browse endpoints mapped to your POS data model: sales, catalog, cash.

2

Authenticate

Obtain a session token via JSON-RPC. One login, reuse across all calls.

3

Integrate

Pull tickets, lines, and catalog into your ERP, BI, or loyalty system.

4

Ship

Go live with read-only sync, hourly sales pulls, and daily cash reconciliation.

Developer experience

Designed with integration teams, not for them

We interviewed POS integrators, BI engineers, and franchise IT leads to understand what makes or breaks an API adoption.

Time to first API call under 2 min

Developers ranked try before read as their top need. Our Playground lets you authenticate and fetch catalog data without writing a single line of code.

REST mental model, JSON-RPC power

Integration teams expect familiar resource paths. We map REST-like endpoints to Ekomium platform models so your team feels at home.

Progressive disclosure

Start with catalog sync, add sales pulls, then cash closures. Each endpoint is independent. Integrate at your own pace.
