Split the bill, in your app.
In one line of code.

Why developers choose Olik Split

Built by app developers for app developers. No tracking, no upsell traps, no per-seat math.

Five-minute integration

Mint a link token from your backend. Drop the SDK in your client. Done.

// 1. Initialize once at app start.
OlikSplitSDK.init(
    config = OlikSplitSDK.Config(
        publishableKey = "pk_test_...",
        environment = OlikSplitSDK.Environment.TEST,
    ),
    sessionStore = SessionStore(applicationContext),
)

// 2. Exchange the link token your backend minted.
val session = OlikSplitSDK.openWithLinkToken("lnk_...")

// 3. Drop the full UI into your screen.
setContent {
    OlikSplitView(onEvent = { event -> println(event) })
}

// 1. Initialize once at launch.
OlikSplitSDK.shared.initialize(
    config: .init(
        publishableKey: "pk_test_...",
        environment: .test
    )
)

// 2. Exchange a link token minted on your backend.
let session = try await OlikSplitSDK.shared
    .openWithLinkToken("lnk_...")

// 3. Present the full SDK UI.
let vc = OlikSplitViewController(linkToken: "lnk_...")
present(vc, animated: true)

import { OlikSplit } from "@oliksplit/sdk";

// 1. Mount the SDK into any DOM container.
OlikSplit.mount("#olik-container", {
  publishableKey: "pk_test_...",
  linkToken: "lnk_...",
});

// 2. Listen for SDK events for analytics or routing.
OlikSplit.on("expense.created", (event) => {
  console.log(event.expenseId);
});

How a request flows

Three tokens, four hops. Read it once, never think about auth again.

1. 1

   Your backend

   Holds the secret key. Mints a single-use link token per end-user before they open your app.

   sk_live_…
3. 2

   Your client

   Initialized once with the publishable key. Receives the link token from your backend and hands it to the SDK.

   pk_live_…
5. 3

   Olik Split SDK

   Exchanges the link token for a session, persists it in secure storage, renders the UI, scans receipts, syncs in real time.

   session_token
7. 4

   Olik API

   Stateless edge in Falkenstein, Germany. Postgres + Redis behind. WebSocket subscriptions fan out group events in < 100 ms.
