Example Usage

Below is an example in Node.js and CPP on how to scan a customer coupon and create a transaction on the k42 platform. 
import * as sdk from "k42-sdk"

const main = async () => {
  const initResult = sdk.initialize({
    platform_endpoint: "https://mesh.transit.dev",
    auth_token: "atu_abc123",

    pos_id: "pos-1",
    location_id: "loc-1"
  });
  if (!initResult.success) {
    console.log(`Failed to initialize ${initResult.message}`);
    return;
  }

  const session = sdk.createSession("customer-ref");
  sdk.setSessionBasketTotal(100);

  const scanResult = await sdk.tokenScan(30000, 3, "platform");
  if (!scanResult.success) {
    console.log(`Failed to scan ${scanResult.message}`);
    sdk.closeSession();
    return;
  }

  const txResult = await sdk.createTransaction("tx-ref", scanResult.token);
  if (!txResult.success) {
    console.log(`Failed to create transaction ${txResult.message}`);
    sdk.closeSession();
    return;
  }

  const finalizeResult = await sdk.finalizeTransaction(txResult.transaction_id);
  if (!finalizeResult.success) {
    console.log(`Failed to create transaction ${finalizeResult.message}`);
    sdk.closeSession();
    return;
  }

  console.log('Transaction successful');
  console.log(`tx id: ${finalizeResult.id}`);
  console.log(`tx auth_code: ${finalizeResult.auth_code}`);
  console.log(`tx credit amount: ${finalizeResult.effects[0].amount}`);
  console.log(`tx coupon id: ${finalizeResult.coupon.id}`);

  const closeResult = sdk.closeSession();
}
