Get your client key and server key from Midtrans Dashboard

Create API client object

`javascript
const midtransClient = require('midtrans-client');
// Create Core API instance
let coreApi = new midtransClient.CoreApi({
isProduction : false,
serverKey : 'YOUR_SERVER_KEY',
clientKey : 'YOUR_CLIENT_KEY'
});
`


`javascript
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:

`javascript
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
`javascript
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';
`

> 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

`javascript
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
}
});
`

$3


Also available as examples here
#### Get Status
`javascript
// 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 Status B2B
`javascript
// get transaction status of VA b2b transaction
apiClient.transaction.statusb2b('YOUR_ORDER_ID OR TRANSACTION_ID')
.then((response)=>{
// do something to response object
});
`
#### Approve Transaction
`javascript
// 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 Transaction
`javascript
// 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
});
`
#### Cancel Transaction
`javascript
apiClient.transaction.cancel('YOUR_ORDER_ID OR TRANSACTION_ID')
.then((response)=>{
// do something to response object
});
`
#### Expire Transaction
`javascript

.then((response)=>{
// do something to response object
});
`
#### Refund Transaction
`javascript
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
});
`
#### Refund Transaction with Direct Refund
`javascript
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
});
`

3. Handling Error / Exception

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:
`javascript
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
})
`

4. Advanced Usage

$3

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 .httpClient.http_client.defaults object, like described in Axios guide. e.g:
`javascript
// 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';
`


$3


As Axios also support interceptor, you can also apply it here. e.g:
`javascript
// 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.

$3

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:
`javascript
// 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:
`javascript
snap.httpClient.http_client.defaults.headers.common['X-Append-Notification'] = 'https://mysite.com/midtrans-notification-handler';
`

Get your API key from Midtrans Iris Dashboard

Create API client object. Note: the serverKey means your API key.

`javascript
const midtransClient = require('midtrans-client');
// Create Core API instance
let iris = new midtransClient.Iris({
isProduction : false,
serverKey : 'YOUR_API_KEY'
});
`

Then perform one of the available functions, using the payload described on Iris docs, e.g:
`javascript
let iris = new midtransClient.Iris({
isProduction : false,
serverKey : 'YOUR_API_KEY'
});

iris.createBeneficiaries({
"name": "Budi Susantoo",
"account": "0611101146",
"bank": "bca",
"alias_name": "budisusantoo",
"email": "budi.susantoo@example.com"

.then((res)=>{
// do something based on the API response
})
.catch((err)=>{
// do something based on the Error object & message
})

You can add or override the header value, by utilizing the withAccessTokenHeader or withTransactionHeader method chain.
Refer to this docs to see the header value required by Snap-Bi , and see the default header on each payment method

`javascript
const midtransClient = require('midtrans-client'); // use this if installed via NPM

let additionalHeader = {
"X-device-id": "your device id",
"debug-id": "your debug id"
}
/**
* Example code for Direct Debit payment using additional header
*/
midtransClient.SnapBi.directDebit()
.withBody(directDebiRequestBody)
.withAccessTokenHeader(additionalHeader)
.withTransactionHeader(additionalHeader)
.createPayment(externalId)
.then(r =>
console.log("Snap Bi result: " + JSON.stringify(r, null, 2))
)
/**
* Example code for using additional header on creating payment using VA
*/
midtransClient.SnapBi.va()
.withBody(vaRequestBody)
.withAccessTokenHeader(additionalHeader)
.withTransactionHeader(additionalHeader)
.createPayment(externalId)
.then(r =>
console.log("Snap Bi result: " + JSON.stringify(r, null, 2))
)
`

If you've saved your previous access token and wanted to re-use it, you can do it by utilizing the .withAccessToken().

`javascript
const midtransClient = require('midtrans-client'); // use this if installed via NPM
/**
* Example reusing your existing accessToken by using .withAccessToken()
*/
midtransClient.SnapBi.directDebit()
.withBody(directDebiRequestBody)
.withAccessToken("your access token")
.createPayment(externalId)
.then(r =>
console.log("Snap Bi result: " + JSON.stringify(r, null, 2))
)

To implement Snap-Bi Payment Notification you can refer to this docs
To verify the webhook notification that you receive you can use this method below
`javascript
const midtransClient = require('midtrans-client'); // use this if installed via NPM

// The request body/ payload sent by the webhook
// Sample notification body, replace with actual data you receive from Midtrans
let notificationPayload = "{\"originalPartnerReferenceNo\":\"GP24043015193402809\",\"originalReferenceNo\":\"A120240430081940S9vu8gSjaRID\",\"merchantId\":\"G099333790\",\"amount\":{\"value\":\"102800.00\",\"currency\":\"IDR\"},\"latestTransactionStatus\":\"00\",\"transactionStatusDesc\":\"SUCCESS\",\"additionalInfo\":{\"refundHistory\":[]}}";

// To get the signature value, you need to retrieve it from the webhook header called X-Signature
let signature = "CgjmAyC9OZ3pB2JhBRDihL939kS86LjP1VLD1R7LgI4JkvYvskUQrPXgjhrZqU2SFkfPmLtSbcEUw21pg2nItQ0KoX582Y6Tqg4Mn45BQbxo4LTPzkZwclD4WI+aCYePQtUrXpJSTM8D32lSJQQndlloJfzoD6Rh24lNb+zjUpc+YEi4vMM6MBmS26PpCm/7FZ7/OgsVh9rlSNUsuQ/1QFpldA0F8bBNWSW4trwv9bE1NFDzliHrRAnQXrT/J3chOg5qqH0+s3E6v/W21hIrBYZVDTppyJPtTOoCWeuT1Tk9XI2HhSDiSuI3pevzLL8FLEWY/G4M5zkjm/9056LTDw==";

// To get the timeStamp value, you need to retrieve it from the webhook header called X-Timestamp
let timeStamp = "2024-10-07T15:45:22+07:00";

// The url path is based on the webhook url of the payment method for example for direct debit is /v1.0/debit/notify
let notificationUrlPath = "/v1.0/debit/notify";
/**
* Example verifying the webhook notification
*/
let isVerified = midtransClient.SnapBi.notification()
.withNotificationPayload(notificationPayload)
.withSignature(signature)
.withTimeStamp(timeStamp)
.withNotificationUrlPath(notificationUrlPath)
.isWebhookNotificationVerified()

Notes

#### Not Designed for Frontend Usage
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.
