Yellow Node.js SDK

This is the Yellow Node SDK. This simple SDK contains couple of node functions that makes it easy to integrate with the Yellow API. To get started just:

sudo npm install yellow-sdk

Examples

var yellow = require('yellow-sdk');

var api_key = 'Eo2XE5SrHcJVdqK9uIDU',
    api_secret = '73jnZflRHpGReqFxzwF_JtynRNmZXoQspPaxTtsy',
    payload = {
            base_ccy   : "USD",
            base_price : "0.05",
            callback   : "https://merchant.com/callback-url"
    };

yellow.createInvoice(api_key, api_secret, payload, function(error, response, body){
    if (!error && response.statusCode == 200) {
        //print the result beautifully
        console.log(JSON.stringify(body, null, 4));
    } else if(error) {
      console.log(error)
    }

});

With no errors, you should see something similar to the following in your terminal:

{
    "address": "155xsayoDXxRFP9rxDoecmpVUo7y5xKtc7", // Invoice Address
    "base_ccy": "USD",
    "base_price": "0.05",
    "callback": "https://example.com",
    "expiration": "2015-03-10T18:17:51.248Z", // Each invoice expires after 10 minutes of creation
    "id": "6dd264975861fddbfe4404ed995f1ca4", // Invoice ID (to query the invoice later if you need to!)
    "invoice_ccy": "BTC",
    "invoice_price": "0.00017070",
    "received": "0",
    "redirect": null,
    "remaining": "0.00017070",
    "server_time": "2015-03-10T18:07:51.454Z",
    "status": "new", // Status of the invoice. Other values are "authorizing" for unconfirmed transactions, and "paid" for confirmed transactions
    "url": "https://cdn.yellowpay.co/invoice.5f0d082e.html?invoiceId=6dd264975861fddbfe4404ed995f1ca4" // Direct URL for the invoice. You can use it to embed the invoice widget in an iframe on your website.
}

To query an invoice that you created, just pass in the invoice_id to the queryInvoice function:

yellow.queryInvoice(api_key, api_secret, invoice_id, function(error, response, body){
    if (!error && response.statusCode == 200) {
        //print the result beautifully
        console.log(JSON.stringify(body, null, 4));
    } else if(error) {
      console.log(error)
    }

});

With no errors, you should get the same invoice data you got when you created the invoice.

Verifying Yellow POST requests

To verify that the request you just receive really is from us, we created a helper function that checks the signature of the request. This method will return true if the signature matches (verified), or false if it doesn't match (not verified).

is_verified = yellow.verifyIPN(api_secret, host_url, request_nonce, request_signature, request_body)

Since this method only works in the context of a web app, check the full demo code for more info on how to use it.
