Midtrans Library for Go(lang)

Midtrans ❤️ Go !

Go is a very modern, terse, and combine aspect of dynamic and static typing that in a way very well suited for web development, among other things. Its small memory footprint is also an advantage of itself. Now, Midtrans is available to be used in Go, too.

Usage blueprint

1. There is a type named Client (midtrans.Client) that should be instantiated through NewClient which hold any possible setting to the library.
2. There is a gateway classes which you will be using depending on whether you used Core, SNAP, or VT-WEB. The gateway type need a Client instance.
3. Any activity (charge, approve, etc) is done in the gateway level.

Example

We have attached usage examples in this repository in folder example/simplepay. Please proceed there for more detail on how to run the example.

Core Gateway

    midclient := midtrans.NewClient()
    midclient.ServerKey = "YOUR-VT-SERVER-KEY"
    midclient.ClientKey = "YOUR-VT-CLIENT-KEY"
    midclient.APIEnvType = midtrans.Sandbox

    coreGateway := midtrans.CoreGateway{
        Client: midclient,
    }

    chargeReq := &midtrans.ChargeReq{
        PaymentType: midtrans.SourceCreditCard,
        TransactionDetails: midtrans.TransactionDetails{
            OrderID: "12345",
            GrossAmt: 200000,
        },
        CreditCard: &midtrans.CreditCardDetail{
            TokenID: "YOUR-CC-TOKEN",
        },
        Items: &[]midtrans.ItemDetail{
            midtrans.ItemDetail{
                Id: "ITEM1",
                Price: 200000,
                Qty: 1,
                Name: "Someitem",
            },
        },
    }

    resp, _ := coreGateway.Charge(chargeReq)

Snap Gateway

Snap is Midtrans existing tool to help merchant charge customers using a mobile-friendly, in-page, no-redirect checkout facilities. Using snap is completely simple.

var snapGateway midtrans.SnapGateway
snapGateway = midtrans.SnapGateway{
  Client: midclient,
}

snapResp, err := snapGateway.GetTokenQuick(generateOrderId(), 200000)
var snapToken string
if err != nil {
  snapToken = snapResp.Token
}

On the client side:

var token = $("#snap-token").val();
snap.pay(token, {
    onSuccess: function(res) { alert("Payment accepted!"); },
    onPending: function(res) { alert("Payment pending", res); },
    onError: function(res) { alert("Error", res); }
});

You may want to override those onSuccess, onPending and onError functions to reflect the behaviour that you wished when the charging result in their respective state.
