Getting Started

Duitku makes the integration process as easy as possible. Allows the Duitku payment page to appear on your web page/application after checkout, with a very easy integration process. Hand over your payment to Duitku Pop. Provide optional payments and confirmation of payments made by customers on your page. Only by you bring Duitku pop on your page.


  1. The user performs the checkout operation.
  2. The merchant server makes an API request to the Duitku payment backend to get the DUITKU_REFERENCE.
  3. Duitku payment backend response to the API call with the DUITKU_REFERENCE.
  4. The merchant server constructs the HTML page and sends it back to the browser.
  5. The user verifies the details and clicks the pay button. Merchant's javascript code calls checkout.process(DUITKU_REFERENCE, options).
  6. Duitku payment backend processes the details and responds with the payment status. Then, Duitku JS calls the corresponding callback provided by the merchant's javascript code.
  7. Duitku payment backend notifies the merchant server about the payment status.

Integration Step

You can use Duitku Library for integration and to start transaction using Duitku on your web or application. For further step you may see Duitku Library on the package repository at each library. Click the link below.

Backend Integration or Server Side

The backend integration goal is to acquire DUITKU_REFERENCE by providing payment information. We provide an HTTP API to do this.

Create Invoice

Create Invoice API is used to get Duitku's reference by sending requirement parameters to the API. Merchant will get Duitku's reference, payment URL as a response from API.

Basic Authentication

Basic Authentication that Duitku uses is signature, timestamp, and merchant code that are sent within request headers.

The signature is the transaction identification code. Contains transaction parameters that have been hashed using the SHA256 hashing method. The hash parameter is merchant code, timestamp, then API key, and should be in order.

The timestamp is a UNIX timestamp in milliseconds within our timezone (Jakarta). The UNIX timestamp is a way to track time as a running total of seconds.

The merchant code is a project ID that has been created and registered at the Duitku merchant page.


Request Headers

To create a valid HTTP request, the merchant needs to use headers like in below:

    successEvent: function(result){
    // your code here
        alert('Payment Success');
    pendingEvent: function(result){
    // your code here
        alert('Payment Pending');
    errorEvent: function(result){
    // your code here
        alert('Payment Error');
    closeEvent: function(result){
    // your code here
        console.log('customer closed the popup without finishing the payment');
