2Checkout Node.js Library
=====================

Full documentation for each binding is provided in the **[wiki](https://github.com/2Checkout/2checkout-node/wiki)**.

This library is forked from the [original 2Checkout Node.js Library](https://github.com/2Checkout/2checkout-node). The difference is that you don't need to clone and then install (which will install to local file)



To use just install with npm.

```shell
npm install 2checkout-nodejs --save
```

Then you can require the module and setup the 2Checkout object with a number of options shown below.

```javascript
// Require the module
var Twocheckout = require('2checkout-node');

// Pass in your private key and seller ID
var tco = new Twocheckout({
    apiUser: "APIuser1817037",                              // Admin API Username, required for Admin API bindings
    apiPass: "APIpass1817037",                              // Admin API Password, required for Admin API bindings
    sellerId: "1817037",                                    // Seller ID, required for all non Admin API bindings 
    privateKey: "3508079E-5383-44D4-BF69-DC619C0D9811",     // Payment API private key, required for checkout.authorize binding
    secretWord: "tango",                                    // Secret Word, required for response and notification checks
    demo: true,                                             // Set to true if testing response with demo sales
    sandbox: false                                          // Uses 2Checkout sandbox URL for all bindings
});
```

Example Admin API Usage

tco.sales.retrieve({sale_id: 205203115664}, function (error, data) {
    if (error) {
        console.log(error);
    } else {
        console.log(data);
    }
});
```

Example Checkout Usage:
-----------------------

*Example Request:*

```javascript
// Setup checkout params
var params = {
    mode: '2CO',
    li_0_name: 'Test Product',
    li_0_price: '0.01'
};

// Get a URL encoded payment link
var link = tco.checkout.link(params);
```

*Example Response:*
```javascript
https://www.2checkout.com/checkout/purchase?mode=2CO&li_0_name=Test%20Product&li_0_price=0.01&sid=1817037
```

Example Return Usage:
---------------------

*Example Request (Using Express):*

```javascript
if (tco.response.valid(request.body), 0.01) {
    response.send("Valid");
} else {
    response.send("Invalid");
}
```

Example INS Notifications Usage:
------------------

*Example Usage (Using Express):*

```javascript
if (tco.notification.valid(request.body)) {
    response.send("Valid");
} else {
    response.send("Invalid");
}
```

Exceptions:
-----------
Errors are returned as the first argument to your callback if they occur. It is best to always check for these before attempting to work with the response.

*Example*

```javascript
tco.checkout.authorize(params, function (error, data) {
    if (error) {
        console.log(error.message);
    } else {
        console.log(JSON.stringify(data));
    }
});
```
