Integration Steps

Integrate Durianpay Checkout with your website to start accepting online payments from your customers. Durianpay supports a slew of payment methods such as bank transfers/VA, credit and debit cards, e-wallets (OVO, Dana, Linkaja) and others. Our checkout library provides all the essential features for integrating Durianpay Checkout with the client-side of your application.

Plaese note that this document only talks about web-based integrations. For mobile, read [here](../mobile/overview)

Preparation

  1. Create a Durianpay account

    If you haven't done it already, click here to sign up. Sign up for Durianpay account here to retrieve API keys for Sandbox environment and to test integrations end-to-end.

  2. Generate API Keys

    Retrieve Sandbox API keys that will be used in next section(s) It is okay to have only the sandbox key for now. If you have live key, you can use it too.

  3. Initialize Durianpay on your server side, if you are using our server SDKs. 

npm install dpay-node-sdk
server.js
const Durianpay = require('dpay-node-sdk');
...
const dpay = new Durianpay({
  secret_key: "your_secret_key", // Use your Sandbox or LIVE key
});

Steps Overview

Step1: Create an order from the server

Use following endpoint to create an order

/orders
server.js
var options = {
  amount: "20000",
  currency: "IDR",
  order_ref_id: "order2314",              // optional, your order reference
  customer: {
    customer_ref_id: "cust_001",          // optional, your customer reference
    given_name: "Imam Sugiarto",
    email: "imam.sugiarto@koss.info",     // mandatory
    mobile: "08972638003",
    address: {                            // optional
        receiver_name: "Jude Casper",
        receiver_phone: "8987654321",
        label: "Judes Address",
        address_line_1: "Cambridge layout",
        address_line_2: "Apartment #786",
        city: "Bangalore",
        region: "Jogupalya",
        country: "Indonesia",
        postal_code: "560008",
        landmark: "Kota Jakarta Selatan"
    }, 
    items: [
        {
            "name": "LED Television",
            "qty": 1,
            "price": "925001.55",
            "logo": "/static/tv_image.jpg"
        }
    ]
  }
};
// Create Orders 
dpay.orders.create(options).then(resp => {
    console.log(resp);
    // order_id = resp.order_id;
})
.catch(error => {
    console.log(error.err + ' | ' + JSON.stringify(error.data));
});
Response
// Sample response
{
  "id": "ord_A31sd3AwAgItmmXdp",
  "customer_id": "cus_rX2ABaMbZJ0050",
  "amount": "20000",
  "currency": "IDR",
  "payment_option": "full_payment",
  "status": "started",
  "order_ref_id": "order2314",
  "address_id": 3863,
  "created_at": "2021-08-04T06:06:37.849813Z",
  "updated_at": "2021-08-04T06:06:37.849813Z",
  "metadata": {},
  "access_token": "adsyoi12sdASd123ASX@qqsda231",
  ...
}

Step 2: Create payments charge from the server

This step will help you create a checkout button on your website which will initiate Durianpay checkout flow for your users seamlessly. The Durianpay checkout modal opens in place without redirecting user to any new tab or url, hence is a much better customer experience leading to better conversions and lower drop offs. You can configure the payment methods in backend with the help of your dedicated Customer success manager easily. Also, you can customize the look and feel at the time of onboarding itself which will forever apply to all your checkout sessions across all devices and users.

Use following endpoint to create a payment

/payments/charge

Error Structure - see Errors for more details

Error
{
  "error": "error message",
  "error_code": "DPAY_INTERNAL_ERROR"
}

Read more: Learn more about Payments API.

Step 3: Redirect user to Wallet/VA checkout on your client, as applicable

You may have to redirect users to respective checkout_url depending on which wallet customer has chosen for the payment. If you receive checkout_url in payment charge API response, please redirect the user to that for them to complete the payment.

Response
// for Wallets
{
  "type": "EWALLET",
  "response": {
    "payment_id": "pay_dAM0lqkVuk0074",
    "order_id": "ord_TVZ6EYuBJ85268",
    "mobile": "08123123123",
    "status": "processing",
    "expiration_time": "2021-04-02T15:08:57.800297779Z",
    "checkout_url": "https://link.to/dana-checkout-url",    "paid_amount": "1000.00",
    "metadata": {},
    ...
  }
}

Once user finishes payemnt successfully on checkout_url, you will automatically receive webhook events as mentioned below in Step 4.

Alternatively, you can also call Payment Status check APIs as mentioned in Step 5.

Step4: Webhooks / Store fields on your servers

Whenever certain transaction actions occur on your Durianpay Checkout integration, we trigger events which your application can listen to. This is where webhooks come in. A webhook is a URL on your server where we send payloads for such events. For example, if you implement webhooks, once a payment is successful, we will immediately notify your server with a payment.completed event. Here is a list of events we can send to your webhook URL.

You can specify your webhook URL on your dashboard (or through your dedicated Customer success manager) where we would send POST requests to whenever an event occurs.

Valid events

payment.completed payment.failed, payment.cancelled, order.created, order.completed

payment.completed
{  
  "event": "payment.completed",
  "data":{  
    "id": "pay_dAS123ad123Asd",
    "signature": "9e892f199d026d06a56669e658a56f264610431d24e8b4d07f7bd46f6d5062d2",
    "order_id": "ord_XXXXXXXXX",
    "amount": "10000",
    "currency": IDR,
    "paid_at": "2016-09-30T21:10:19.000Z",
    "created_at":"2016-09-30T21:09:56.000Z",
    "metadata": {
      "key": "value"
    },
}

Step5: Verify payment status (Optional)

You will get payment_id through webhook callback (if configured). You should ideally try to validate the payment and store the details in your server/database against the order/transaction accordingly.

First, you need to get verification signature from Durianpay which would have been provided to you in your webhook callback. 

{  
  "event": "payment.completed",
  "data":{  
    "id": "pay_dAS123ad123Asd",
    "signature": "9e892f199d026d06a56669e658a56f264610431d24e8b4d07f7bd46f6d5062d2",    ...
}

If you didn't receive it for any reason, you can call payment status check API from your server/backend which will respond back with signature if status of payment is completed.

/payments/:id/status
"status": "completed",
"is_completed": true,
"signature": "9e892f199d026d06a56669e658a56f264610431d24e8b4d07f7bd46f6d5062d2"

This signature is computed by us using payment_id, amount and your secret key. You need to create the hash on your server/backend where you have all these elements and match with the signature provided by us.

Sample code for signature generation 

// Function to generate the signature for verification of payment
//use appropriate key if it is a sandbox order please use dp_test key and if it is a live order then use dp_live key
func GenerateSignature(paymentID string, amount string, accessKey string) (generatedSignature string) {
  //message passed includes payment_id + “|” + amount. Amount is in “15000.00” format
  secretData := paymentID + "|" + amount
  // Create a new HMAC by defining the hash type and the key (as byte array)
  h := hmac.New(sha256.New, []byte(accessKey))
  // Write Data to it
  h.Write([]byte(secretData))
  // Get result and encode as hexadecimal string
  generatedSignature = hex.EncodeToString(h.Sum(nil))
  return
}

Test Integration

Test payments

You can use following test payment credentials to test payments.

Verify Payment status

Through Dashboard

  1. Log into the Dashboard and navigate to Payments in sidebar.
  2. Check if a payment_id has been generated. If no payment_id has been generated, it means that the transaction has failed (and didn't even initiate from user's end)
Durian Dashboard 1

Through APIs

Use following endpoint to do status check on a payment (Read more about Payment Status Check API)

/payments/:id/status
curl -u <YOUR_SECRET_KEY> \
-X GET https://api.durianpay.id/v1/payments/pay_B14sdfwAdmmSDF24a/status \
-H "content-type: application/json"'
Response
{
    "data": {
        "status": "completed",
        "is_completed": true,
        "signature": "9e892f199d026d06a56669e658a56f264610431d24e8b4d07f7bd46f6d5062d2"
    }
}

Accept LIVE payments

After testing the flow of funds end-to-end in sandbox mode, you can switch to the live mode and start accepting payments from your customers. However, make sure that you swap the test API keys with the live keys.

  1. Log into Dashboard and switch to Live mode on the sidebar menu.
  2. Navigate to Settings → API Keys to access your API key for live mode.
  3. Replace the sandbox API key with the Live Key in the Checkout code and start accepting real-time payments.
