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';

.then((response)=>{
// do something to `response` object
});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'){
// capture only applies to card transaction, which you need to check for the fraudStatus
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 == 'settlement'){
// TODO set transaction status on your databaase to 'success'
} else if (transactionStatus == 'deny'){
// TODO you can ignore 'deny', because most of the time it allows payment retries
// and later can become success
} else if (transactionStatus == 'cancel' ||
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
})Under the hood this API wrapper is using Axios as http client. You can override the default config.
You can set via the value of this <api-client-instance>.httpClient.http_client.defaults object, like described in Axios guide. e.g:
// create instance of api client
let snap = new midtransClient.Snap({
isProduction : false,
serverKey : 'YOUR_SERVER_KEY',
clientKey : 'YOUR_CLIENT_KEY'
});
// set Axios timeout config to 2500
snap.httpClient.http_client.defaults.timeout = 2500;
// set custom HTTP header for every request from this instance
snap.httpClient.http_client.defaults.headers.common['My-Header'] = 'my-custom-value';As Axios also support interceptor, you can also apply it here. e.g:
// Add a request interceptor
snap.httpClient.http_client.interceptors.request.use(function (config) {
// Do something before request is sent
return config;
}, function (error) {
// Do something with request error
return Promise.reject(error);
});It can be used for example to customize/manipulate http request's body, header, etc. before it got sent to the destination API url.
As described in API docs, merchant can opt to change or add custom notification urls on every transaction. It can be achieved by adding additional HTTP headers into charge request.
This can be achived by:
// create instance of api client
let snap = new midtransClient.Snap({
isProduction : false,
serverKey : 'YOUR_SERVER_KEY',
clientKey : 'YOUR_CLIENT_KEY'
});
// set custom HTTP header that will be used by Midtrans API to override notification url:
snap.httpClient.http_client.defaults.headers.common['X-Override-Notification'] = 'https://mysite.com/midtrans-notification-handler';or append notification:
snap.httpClient.http_client.defaults.headers.common['X-Append-Notification'] = 'https://mysite.com/midtrans-notification-handler';Iris is Midtrans’ cash management solution that allows you to disburse payments to any bank accounts in Indonesia securely and easily.

This library/package is mainly NOT FOR FRONTEND (Browser's javascript) usage, but for backend (Node JS server) usage:
- This is mainly for backend usage, to do secure server-to-server/backend-to-backend API call.
- You may/will encounter CORS issue if you are using this to do API request from frontend.
- Your API ServerKey may also be exposed to public if you are using this on frontend.
- If what you need is to display Snap payment page on your frontend, please follow this official documentation
- If you are using ReactJS follow this recommendation.
