I went to a workshop on Integrating Telco API (Voice and SMS). After going through the API docs and figuring out the API and setting it up on my server with PHP in 25minutes, I was left with 5 minutes to work on the Interface. Whiles a lot of people were working with Web Frameworks, I decided to use B4A.
....In 5 minutes -I started the IDE, loaded the Designer, Added couple of buttons and Edittext,
-Declared them, Added Okhttputils and JSON Lib,
-Initiated a call to the URL to my server where the API resides,
-Received JSON response and processed it
-Then Displayed a successful confirmation message box
Sure I basically copy and pasted the API and inputted my credentials...That also less than 5 minutes
Studying the docs took a longer time, the Trial Token given us does not accept some parameters which we were not made aware. So i kept getting an error even though I was using the correct values
