Shopify Related Products

I was looking for a way to control the related products shown below a product (for cross-selling) without using an external app, and came up with a very basic and easy to use template and collection solution.

Unit4 Multivers .netAPI

If you want to synchronize certain products from multivers with another (online) application, you can choose to use Unit4 Multivers .net API or the Unit4 multivers webAPI to make sure you are able to use them with your license, contact your accountmanager first.

I chose to use the .netapi because we didn’t want our multivers server to be directly connected to the internet with the web API. that’s why unit4 would post product update data to the webapplication, and load specific product data from the webapplication to update unit4 as well.

Sitecom WLC-1000 Firmware Information

Unfortunately the company that created the iphone and android application has filed for bankruptcy, rendering the wlc-1000 cameras useless for checking your cameras on the road or recording to the cloud (recording on the sdcard should still work as far as I know).

A visitor asked me to share some of my findings for the sitecom firmware, because he wants to create an app to be able to use the cameras again, which sounds like a great idea!
It has been a while since I did the analysis, but I will try and share as much as I found, so anyone can try and setup a working application. With one side note, please share your projects, or setup a public repository, so other people can help / benefit from the code as well (and share it in the comments below).

Shopify Script, Buy Product from vendor X get Product Y for free

In shopify I was looking for a way to get a free product when buying from a specific vendor, I came up with below script.
In our case we also needed the vendor’s product to be at > $400 for the gift product to be free, you can offcourse remove that if statement.
Unfortunately you can’t add products to the cart with shopify scripts (yet?) so you can leave adding the product up to the customer, or add the product with javascript in the frontend.

You can remove the puts statements, I though I’d leave them so you can see how to debug something like this.


Large databreach, how to minimize online vulnerabilities, and improve responsetime

Last week I found a data breach in a large companies website, exposing over 2 million customer records (name, address, email, phone number)
It’s always a though choice, do I call it in and risk getting sued, or leave it? Since this was quite a big leak, which I more or less stumbled upon (think in the lines of ‘this looks odd, what happens if I try and change this’) , I just went ahead and stated my intensions very clearly in my messages, and hoped they would see it would benefit them to use my report, and fix the problem as soon as possible.

Push Notify Push notification API


I created an api for sending Push notifications to mobile phones, I use the API in an opencart extension, to send new order information, and give clients the ability to receive order updates, but I figured it might be usefull for other developers to have a quick way to add push notification functionality in their application.

I’m currently writing the API documentation, you can find the basic documentation here:
Swagger API Documentation

The basic workflow:

  • Create a user & receive an API key
  • Create a channel
  • Have mobile devices subscribe to channels
  • Send a message to channels


In the opencart extensions case I create one channel for the admin, and a unique private channel for each customer (after an order is placed) which they can use to receive order status updates (pending, complete, shipped, cancelled etc..)

To receive mobile notifications you will need the Iphone or Android app.
