For a long time I've been selling some products in Tindie.com a shop the hadware of makers for makers, every time you make a sale of a product you receive a notification in you email with the data of client for ship.
Tindie also has an API with the that you can know state of the shipments, i did a project with my Arduino MKR1000 for use Tindie API and notify me when there is a new order.
NOTE: The first thing a knows is that Tindie manage TLS 1.2, that's why you can't use the ESP8266 for it's project and that's why i am using Arduino MKR1000 with support for TLS 1.2.
Now the first thing to understand is the Tindie API and get you API key for make the next request:
After you have to install the library "WiFi 101" from Manage Library of the Arduino IDE
And install the board Arduino MKR1000 from Manage Boards of the Arduino IDE "Arduino SAMD Board 32 bits"
The Code for work you can find it in the section "Code" with the link to my repository in github. In the code you should only change the variables for your data "username" and "API key"
Is the time to assemble the strucuture of "Tindie Dog" in acrilyc that is very easy the build in the laser machine and the section of attanchments you can find the appropriates files.
And with that you will have everything ready!!
