First API request

Now that your Sandbox API credentials are ready, you can make your first authenticated request using the Elite Neo Bank Payment Gateway APIs. In this guide, you will:

Create your first payment order
Generate authentication headers
Send an authenticated API request
Receive a hosted checkout payment link

Before continuing, ensure you have already completed:

Account onboarding
Sandbox credential generation
Authentication setup

Recommended prerequisites: ➡️ Generate API Credentials
➡️ Authentication → Headers
➡️ Authentication → Timestamp
➡️ Authentication → Signature

Create Your First Payment Order

The Create Order API generates a hosted checkout session and returns a secure payment link that can be shared with customers. Example request payload:

{
  "order_id": 6116229263036,
  "order_amount": 105,
  "order_currency": "INR",
  "order_note": "Additional order info",
  "service_type": "DIGITAL",
  "customer": {
    "name": "Ajay",
    "email": "developer@jangras.co",
    "phone": "9816512345",
    "address": {
      "line1": "Capital Office, Kemp House",
      "line2": "152 - 160 City Road",
      "city": "London",
      "state": "London",
      "country": "UK",
      "postal_code": "EC1V 2NX"
    }
  },
  "return_url": "https://merchant.in/process_return.php?order_id=order_1626945143520"
}

Generate Authentication Headers

Before sending the request:

Generate a UNIX timestamp
Generate the HMAC SHA256 signature
Attach authentication headers

Required authentication headers: ➡️ Authentication → Headers
➡️ Authentication → Timestamp
➡️ Authentication → Signature

Send Your First API Request

Example cURL request:

curl --request POST \
--url https://sandbox.Elite Neo Bank.com/api/v3/pg/order/create \
--header "Content-Type: application/json" \
--header "Accept: application/json" \
--header "X-API-KEY: YOUR_API_KEY" \
--header "X-SIGNATURE: GENERATED_SIGNATURE" \
--header "X-TIMESTAMP: GENERATED_TIMESTAMP" \
--data '{
  "order_id": 6116229263036,
  "order_amount": 105,
  "order_currency": "INR",
  "order_note": "Additional order info",
  "service_type": "DIGITAL",
  "customer": {
    "name": "Ajay",
    "email": "developer@jangras.co",
    "phone": "9816512345"
  },
  "return_url": "https://merchant.in/process_return.php?order_id=order_1626945143520"
}'

Example Success Response

{
  "code": "200",
  "status": "success",
  "message": "API authentication successful!",
  "return_data": {
    "kwikX_order_id": "kp_40dec464-7155-43a3-855d-c95c5ab1be71",
    "created_at": "13-05-2026 08:34 AM",
    "order_id": 3501946751751,
    "order_status": "UN_PAID",
    "payment_link": "https://sandbox.Elite Neo Bank.com/payment/pay_TSN7ASUDmzcZNyH8qLeG8PrR4CWB9pwFQOuDPYia0fd5k2fMzN"
  }
}

Redirect Customer to Hosted Checkout

Use the returned:

payment_link

to redirect customers to the Elite Neo Bank Hosted Checkout page. Example:

window.location.href = payment_link;

Customers can then complete payment securely using the hosted payment interface.

Verify Payment Status

After payment completion:

Verify payment status server-side
Use the Order Status API
Validate webhook notifications
Reconcile transaction records

Recommended references: ➡️ Payment Gateway → Order Status API
➡️ Webhooks → Webhook Setup
➡️ Webhooks → Signature Verification
