Missed call to pay on KooKoo using UPI

The launch of UPI can be considered as a watershed moment. This has opened up a whole new way of sending and receiving payments and will surely lead to a lot of innovation.
The API is really well designed for a government effort. But guess it was expected given the great efforts put in by a lot of volunteers. So,hats off to them.
Whenever innovative things happen, you know KooKoo is not far behind :)
So, in this blog post, I will show you an easy way to collect payments using a missed call.

1. Register for a KooKoo missed call account. and specify an app URL. You will receive a missed call number.
2. When some one calls on your missed call number, KooKoo makes a http request to your URL with the caller details.
3. Build UPI payment request URL based on specification provided by NCPI. So lets say your VPA is ozonetel@somebank and you need to request Rs.2, your request will be something like, upi://pay?pa=ozonetel@somebank&am=2.
4. Send this link in an SMS back to the caller. The caller can use this link to pay for the amount.

Wanna see this in action, just give a

I have made some small adjustments. Since the upi:// protocol is still not recognized by messaging apps, I have redirected through a web URL so that the link becomes clickable. Just click on the link in the SMS and pay. This assumes you have an app installed which understands UPI(This is most of the bank apps)

This is a very basic use case which we have showcased. You can now use a phone number to collect payments. You can even do IVR payments

UPI is still in early stages. This is really good for P2P payments, but the merchant payment piece is still lagging in some respects. I am sure, things will be resolved soon.

Integrating Arborjs with Angular to create a live calls dashboard

Arborjs  is a cool graph visualization library. Angular  is one of the best JavaScript frameworks and we have been using Angular in a lot of our front end development. When you handle millions of calls, proper visualization becomes very important. Without proper visualization, you can get lost in the mountains of data. So we spend a lot of time to come up with good visualizations to represent the data. Since we loved the cool way in which Arbor represented graph data, we could not wait to hook it up with Angular. Because of Angular's two way data binding, when you hook up Angularjs with Arbor.js you can get a dynamically updated visualization of graph data with cool animations. To give back to the community, we have put up the code online at Github . Basically we have created an Angularjs directive for Arborjs. Please feel free to fork the code and add extensions and use it for your own visualizations. The code is self explanatory with comments inline. Best way to get s

Google's approach to business communication

 Google has been making silent moves in the business communication space. Google has mostly lost the instant messaging wars. But it does not want to lose the business communication war. WhatsApp, Instagram, Twitter and Facebook have been making their own moves to enable businesses to reach their customers through their channels. Its all about who has control over the communication channels. Especially communication which leads to business. That's where the money is.

And they have started making the moves. WhatsApp business allows small businesses to conduct their transactions on WhatsApp. FB and Instagram have long supported small businesses to manage their business on their channels. Apple has also made some nice moves with Apple business chat. They have integrated a whole shopping expe
