Embedded Form

Subotiz supports completing checkout flows through embedded forms, offering a low-code payment integration solution. Easily create customizable payment forms to accelerate your payment implementation.

Integration Scenario Demos

This page explains how to use the Payment integration mode. This approach involves calling only Subotiz’s payment engine, allowing you to fully design and build your own front-end interface and business logic. If you require comprehensive product management, subscription, and payment capabilities, please proceed to Embedded Checkout.

Payment Flow

When a customer is ready to complete a purchase, initiate a checkout request from your client-side application to your server. Your server should use the Subotiz API to create a Checkout Session, passing the order_id (your platform’s unique order identifier) as a parameter to facilitate subsequent association with the trade order.
The Checkout Session returns a Session ID. Your client-side application can then use the SDKs to invoke and display the Subotiz payment form to the customer.
The customer enters their payment details into the form and completes the transaction.
After the transaction is completed, Subotiz will notify your server via a webhook. This notification includes a payment success event containing the order_id passed during session creation, enabling you to correlate your platform’s order with Subotiz’s trade order.

Integration Steps

Provide a Webhook Endpoint

Create an endpoint to receive events for your account. When an event occurs, Subotiz will send an HTTPS POST request containing a JSON-formatted event object to this Webhook endpoint. You can use these events to keep your system’s business data in sync.

Integrate Embedded Form

Your client-side application can use the Subotiz SDK to integrate Subotiz Checkout.

1. Load Subotiz.js

<script src="https://checkout.subotiz.com/static/subotiz/v0/subotiz.js"></script>

2. Provide Container Element

<div id="your_domElement">
    <!-- Checkout page will be displayed here -->
</div>

3. Create Checkout Session

Use the Subotiz API to create a Checkout Session , and return the response to your frontend.Example: Creating a Checkout Session in Embedded Mode:

curl --location 'https://api.subotiz.com/api/v1/session' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer {your_api_key}' \
--header 'Request-Id: dd7fb126-be31-4144-a1af-e4bf4203eb92' \
--data-raw '{
        "access_no":       "77d52a21dc032b4",
        "sub_merchant_id": "2816433",
        "order_id":        "123e4567-e89b-12-a456-426622201a",
        "payer_id": "customer_id_001",
        "customer_id":     "",
        "email":           "[email protected]",
        "return_url":   "https://www.subotiz.com",
        "cancel_url":   "https://www.subotiz.com",
        "mode": "payment",            # Select payment mode when no product data is present
        "total_amount": "10",         # Amount to collect (required for payment mode)
        "integration_method": "embedded",    # Choose embedded integration
        "redirect_on_completion": "if_required" # Configure redirection behavior; this example only redirects when necessary
    }'

Key Parameters

order_id: Your platform’s internal order ID for subsequent business data correlation
integration_method: Set to embedded to use the embedded form integration method
return_url: URL to redirect customers to after successful payment on the Subotiz Checkout page
mode: Choose payment mode
total_amount: Amount for this checkout session

4. Initialize Checkout Page

// After importing via the script tag, Subotiz is automatically attached to the window object
const {
    Subotiz
} = window;

// Create an SDK instance
const subotiz = Subotiz();

// Initialize checkout
const checkout = await subotiz.initEmbeddedCheckout({
    fetchSessionUrl: async() => {
        // Fetch the sessionUrl from your server
        const response = await fetch('/api/session');
        const data = await response.json();
        return data.sessionUrl;
    },
    environment: 'SANDBOX',// 'SANDBOX' | 'PRODUCTION'
    // The callback function when the payment completed only triggers when `redirect_on_completion`  is set to `if_required` during Checkout session creation
    onComplete: () => {
        console.log('Payment completed!');
    }
});

// Mount to the page
checkout.mount('#checkout-container');

Subscription Renewal Payments

Subotiz supports subscription renewal payments. After a customer completes the initial payment, the system generates a payment credential. Subsequent subscription fees for this customer can be charged using this payment credential without requiring the customer to re-enter payment details.

Renewal Process

After the customer completes the initial payment, save the payment_token data from the payment success event (trades.succeeded) to initiate renewal charges.
Use the Create Trade API endpoint in the Subotiz API to initiate the charge.
Proactively query the trade order or wait for an asynchronous notification to obtain the payment result, then notify the customer accordingly.
