Pay for an order as a registered user

Signs in a user, creates an order and opens a payment session for it. With an online payment account, redirect the user to the session's paymentUrl.

What this example does:

  • Signs in a registered user
  • Creates an order
  • Creates a payment session

Prerequisites:

  • A valid PROJECT_URL and APP_TOKEN for the OneEntry API.
  • A registered user
  • Configured order storage with marker "orders"

Notes:

  • The examples handle errors minimally: they throw when a call returns an error object.
  • By default (isShell: true) the SDK returns an error object instead of throwing, so check the result, e.g. 'statusCode' in result. With isShell: false it throws, and you handle errors with try/catch. See Errors.

Run this example in the JS SDK sandbox. Connect your Project URL and App Token on first visit, then open:

Scenario​

1. Import defineOneEntry and define PROJECT_URL and APP_TOKEN​

import { defineOneEntry } from 'oneentry';
import type { IOrderData } from 'oneentry';

const PROJECT_URL = 'https://your-project.oneentry.cloud';
const APP_TOKEN = 'your-app-token';

2. Create an API client​

const { AuthProvider, Orders, Payments } = defineOneEntry(PROJECT_URL, {
  token: APP_TOKEN,
});

3. Authenticate the user with AuthProvider.auth('email', authData)​

const authData = {
  authData: [
    {
      marker: 'email_reg',
      value: 'your-email',
    },
    {
      marker: 'password_reg',
      value: 'your-password',
    },
  ],
};
const user = await AuthProvider.auth('email', authData);

if ('statusCode' in user) {
  throw new Error(user.message);
}

console.log(user);
Result:
{
  "userIdentifier": "john@example.com",
  "authProviderIdentifier": "email",
  "accessToken": "eyJhbGciOiJIUzI1NiIsInR...pZCI6MTYsImF1dGhQ",
  "refreshToken": "1745494429101-...-2834edf8"
}

4. Create an order with Orders.createOrder()​

const body: IOrderData = {
  formIdentifier: 'order',
  paymentAccountIdentifier: 'cash',
  formData: [
    {
      type: 'string',
      marker: 'name',
      value: 'John Smith',
    },
  ],
  products: [
    {
      productId: 15,
      quantity: 1,
    },
  ],
};
const orderData = await Orders.createOrder('orders', body);

if ('statusCode' in orderData) {
  throw new Error(orderData.message);
}
Result:
{
  "id": 116,
  "formIdentifier": "order",
  "paymentAccountIdentifier": "cash",
  "formData": [
    {
      "type": "string",
      "marker": "name",
      "value": "John Smith"
    }
  ],
  "products": [
    {
      "productId": 15,
      "quantity": 1
    }
  ],
  "currency": "USD",
  "totalSum": 400,
  "bonusApplied": 0,
  "totalDue": 400,
  "discountConfig": {
    "orderDiscounts": [],
    "productDiscounts": [],
    "coupon": null,
    "settings": {
      "allowStacking": false,

      "allowGiftStacking": false,

      "maxBonusDiscount": 0,
      "minBonusAmount": null,
      "minOrderAmountForBonus": null,

    },

  "statusLocalizeInfos": {
    "title": "Upcoming"
  },
  "createdDate": "2026-06-06T11:38:21.644Z"
}

5. Create a payment session with Payments.createSession()​

const sessionData = await Payments.createSession(orderData.id, 'session');

if ('statusCode' in sessionData) {
  throw new Error(sessionData.message);
}

Result:
{
  "id": 65,
  "createdDate": "2026-06-06T11:38:22.125Z",
  "updatedDate": "2026-06-06T11:38:22.125Z",
  "type": "session",
  "status": "waiting",
  "paymentAccountId": 1,
  "orderId": 116,
  "amount": null,
  "paymentUrl": null
}

6. Get the payment session by order ID with Payments.getSessionByOrderId()​

const sessionByOrderId = await Payments.getSessionByOrderId(orderData.id);

if ('statusCode' in sessionByOrderId) {
  throw new Error(sessionByOrderId.message);
}

console.log({ user, sessionData, sessionByOrderId });
Result:
[
  {
    "id": 65,
    "createdDate": "2026-06-06T11:38:22.125Z",
    "updatedDate": "2026-06-06T11:38:22.125Z",
    "type": "session",
    "status": "waiting",
    "paymentAccountId": 1,
    "orderId": 116,
    "amount": null,
    "paymentUrl": null
  }
]

import { defineOneEntry } from 'oneentry';
import type { IOrderData } from 'oneentry';

const PROJECT_URL = 'https://your-project.oneentry.cloud';
const APP_TOKEN = 'your-app-token';

// 2. Create an API client
const { AuthProvider, Orders, Payments } = defineOneEntry(PROJECT_URL, {
  token: APP_TOKEN,
});

// 3. Sign in
const authData = {
  authData: [
    {
      marker: 'email_reg',
      value: 'your-email',
    },
    {
      marker: 'password_reg',
      value: 'your-password',
    },
  ],
};
const user = await AuthProvider.auth('email', authData);

if ('statusCode' in user) {

console.log(user);

// 4. Create an order
const body: IOrderData = {

const orderData = await Orders.createOrder('orders', body);

if ('statusCode' in orderData) {
  throw new Error(orderData.message);
}

// 5. Create a payment session
const sessionData = await Payments.createSession(orderData.id, 'session');

if ('statusCode' in sessionData) {
  throw new Error(sessionData.message);
}

// 6. Get the payment session by order ID
const sessionByOrderId = await Payments.getSessionByOrderId(orderData.id);
