If you are not using NPM, you can clone or download this repository.
Then require from index.js file.
let midtransClient = require('./midtrans-client-nodejs/index.js');
We have 2 different products of payment that you can use:
Choose one that you think best for your unique needs.
Get your client key and server key from Midtrans Dashboard
Create API client object
const midtransClient = require('midtrans-client');
// Create Core API instance
let coreApi = new midtransClient.CoreApi({
isProduction : false,
serverKey : 'YOUR_SERVER_KEY',
clientKey : 'YOUR_CLIENT_KEY'
});
const midtransClient = require('midtrans-client');
// Create Snap API instance
let snap = new midtransClient.Snap({
isProduction : false,
serverKey : 'YOUR_SERVER_KEY',
clientKey : 'YOUR_CLIENT_KEY'
});
You can also re-set config using Snap.apiConfig.set( ... )
example:
const midtransClient = require('midtrans-client');
// Create Snap API instance, empty config
let snap = new midtransClient.Snap();
snap.apiConfig.set({
isProduction : false,
serverKey : 'YOUR_SERVER_KEY',
clientKey : 'YOUR_CLIENT_KEY'
});
// You don't have to re-set using all the options,
// i.e. set serverKey only
snap.apiConfig.set({serverKey : 'YOUR_SERVER_KEY'});
You can also set config directly from attribute
const midtransClient = require('midtrans-client');
// Create Snap API instance, empty config
let snap = new midtransClient.Snap();
snap.apiConfig.isProduction = false;
snap.apiConfig.serverKey = 'YOUR_SERVER_KEY';
snap.apiConfig.clientKey = 'YOUR_CLIENT_KEY';
You can see Snap example here.
Available methods for Snap class
// return Snap API /transaction response as Promise of Object
createTransaction(parameter)
// return Snap API /transaction token as Promise of String
createTransactionToken(parameter)
// return Snap API /transaction redirect_url as Promise of String
createTransactionRedirectUrl(parameter)
parameter is Object or String of JSON of SNAP Parameter
const midtransClient = require('midtrans-client');
// Create Snap API instance
let snap = new midtransClient.Snap({
isProduction : false,
serverKey : 'YOUR_SERVER_KEY',
clientKey : 'YOUR_CLIENT_KEY'
});
let parameter = {
"transaction_details": {
"order_id": "test-transaction-123",
"gross_amount": 200000
}, "credit_card":{
"secure" : true
}
};
snap.createTransaction(parameter)
.then((transaction)=>{
// transaction token
let transactionToken = transaction.token;
console.log('transactionToken:',transactionToken);
})
// alternative way to create transactionToken
// snap.createTransactionToken(parameter)

On frontend / html:
Replace PUT_TRANSACTION_TOKEN_HERE with transactionToken acquired above
<html>
<body>
<button id="pay-button">Pay!</button>
<pre><div id="result-json">JSON result will appear here after payment:<br></div></pre>
<!-- TODO: Remove ".sandbox" from script src URL for production environment. Also input your client key in "data-client-key" -->
<script src="https://app.sandbox.midtrans.com/snap/snap.js" data-client-key="<Set your ClientKey here>"></script>
<script type="text/javascript">
document.getElementById('pay-button').onclick = function(){
// SnapToken acquired from previous step
snap.pay('PUT_TRANSACTION_TOKEN_HERE', {
// Optional
onSuccess: function(result){
/* You may add your own js here, this is just example */ document.getElementById('result-json').innerHTML += JSON.stringify(result, null, 2);
},

You can see some Core API examples here.
Available methods for CoreApi class
/**

* @param {Object} parameter - object of Core API JSON body as parameter, will be converted to JSON (more params detail refer to: https://api-docs.midtrans.com)
* @return {Promise} - Promise contains Object from JSON decoded response
*/
charge(parameter={})
/**
* Do `/capture` API request to Core API
* @param {Object} parameter - object of Core API JSON body as parameter, will be converted to JSON (more params detail refer to: https://api-docs.midtrans.com)
* @return {Promise} - Promise contains Object from JSON decoded response
*/
capture(parameter={})
/**
* Do `/card/register` API request to Core API
* @param {Object} parameter - object of Core API JSON body as parameter, will be converted to JSON (more params detail refer to: https://api-docs.midtrans.com)

* @return {Promise} - Promise contains Object from JSON decoded response
*/
cardPointInquiry(tokenId)
parameter is Object or String of JSON of Core API Parameter
Get token should be handled on Frontend please refer to API docs
const midtransClient = require('midtrans-client');
// Create Core API instance
let core = new midtransClient.CoreApi({
isProduction : false,
serverKey : 'YOUR_SERVER_KEY',
clientKey : 'YOUR_CLIENT_KEY'
});
let parameter = {
"payment_type": "credit_card",
"transaction_details": {
"gross_amount": 12145,
"order_id": "test-transaction-54321",
},
"credit_card":{
"token_id": 'CREDIT_CARD_TOKEN', // change with your card token
"authentication": true
}
};
// charge transaction
core.charge(parameter)
.then((chargeResponse)=>{
console.log('chargeResponse:');
console.log(chargeResponse);
});
The credit card charge result may contains redirect_url for 3DS authentication. 3DS Authentication should be handled on Frontend please refer to API docs
For full example on Credit Card 3DS transaction refer to:
IMPORTANT NOTE: To update transaction status on your backend/database, DO NOT solely rely on frontend callbacks! For security reason to make sure the status is authentically coming from Midtrans, only update transaction status based on HTTP Notification or API Get Status.
Create separated web endpoint (notification url) to receive HTTP POST notification callback/webhook. HTTP notification will be sent whenever transaction status is changed. Example also available here
const midtransClient = require('midtrans-client');
// Create Core API / Snap instance (both have shared `transactions` methods)
let apiClient = new midtransClient.Snap({
isProduction : false,
serverKey : 'YOUR_SERVER_KEY',
clientKey : 'YOUR_CLIENT_KEY'
});
apiClient.transaction.notification(notificationJson)
.then((statusResponse)=>{
let orderId = statusResponse.order_id;
let transactionStatus = statusResponse.transaction_status;
let fraudStatus = statusResponse.fraud_status;
console.log(`Transaction notification received. Order ID: ${orderId}. Transaction status: ${transactionStatus}. Fraud status: ${fraudStatus}`);
// Sample transactionStatus handling logic
if (transactionStatus == 'capture'){
if (fraudStatus == 'challenge'){
// TODO set transaction status on your databaase to 'challenge'
} else if (fraudStatus == 'accept'){
// TODO set transaction status on your databaase to 'success'
}
} else if (transactionStatus == 'cancel' ||
transactionStatus == 'deny' ||
transactionStatus == 'expire'){
// TODO set transaction status on your databaase to 'failure'
} else if (transactionStatus == 'pending'){
// TODO set transaction status on your databaase to 'pending' / waiting payment
}
});
Also available as examples here
// get status of transaction that already recorded on midtrans (already `charge`-ed)
apiClient.transaction.status('YOUR_ORDER_ID OR TRANSACTION_ID')
.then((response)=>{
// do something to `response` object
});
// get transaction status of VA b2b transaction
apiClient.transaction.statusb2b('YOUR_ORDER_ID OR TRANSACTION_ID')
.then((response)=>{
// do something to `response` object
});
// approve a credit card transaction with `challenge` fraud status
apiClient.transaction.approve('YOUR_ORDER_ID OR TRANSACTION_ID')
.then((response)=>{
// do something to `response` object
});
// deny a credit card transaction with `challenge` fraud status
apiClient.transaction.deny('YOUR_ORDER_ID OR TRANSACTION_ID')
.then((response)=>{
// do something to `response` object
});
apiClient.transaction.cancel('YOUR_ORDER_ID OR TRANSACTION_ID')
.then((response)=>{
// do something to `response` object
});
apiClient.transaction.expire('YOUR_ORDER_ID OR TRANSACTION_ID')
.then((response)=>{
// do something to `response` object
});
let parameter = {
"refund_key": "order1-ref1",
"amount": 5000,
"reason": "Item out of stock"
}
apiClient.transaction.refund('YOUR_ORDER_ID OR TRANSACTION_ID',parameter)
.then((response)=>{
// do something to `response` object
});
let parameter = {
"refund_key": "order1-ref1",
"amount": 5000,
"reason": "Item out of stock"
}
apiClient.transaction.refundDirect('YOUR_ORDER_ID OR TRANSACTION_ID',parameter)
.then((response)=>{
// do something to `response` object
});
When using function that result in Midtrans API call e.g: core.charge(...) or snap.createTransaction(...)
there's a chance it may throw error (MidtransError object), the error object will contains below properties that can be used as information to your error handling logic:
snap.createTransaction(parameter)
.then((res)=>{
})
.catch((e)=>{
e.message // basic error message string
e.httpStatusCode // HTTP status code e.g: 400, 401, etc.
e.ApiResponse // JSON of the API response
e.rawHttpClientData // raw Axios response object
})
