This is, two files written to get data from SigFox backend, one to get message list, and other one to get the device type, it’s can be a good start for your application if you are not familiar with php and json, just edit the file, put your informations, and upload to your server. Data from backend are collected through curl and GET method, stored in a json file (be careful with security permissions) and decoded with json_decode function.
