PHP

Since PHP as built in functions to encode/decode JSON it provides a quick and easy method to test the API.

Using OOP is the most sensible approach so create a class called Job.

Job.php

class Job {
 
	public $job_number;
	public $address_1;
	public $address_2;
	public $contact_name;
	public $contact_number_1;
	public $contact_number_2;
	public $mobile_user = array();//username not id
	public $postcode;
	public $type = 'repair';//job type in mmw
	public $timeslot;
	public $special_instructions;
	public $repair_description;
 
function __construct(){
 
//Here you could pass an ID and populate the job from a mysql record etc..
 
$job_number = "TEST_JOB01";
$address_1 = "ADDRESS LINE 1";
-------- populate further records
$repair_description = "Faulty whatsit";
 
 
}
 
function getJSON(){
	// we have a container array so the structure what the API expects
	// we send 1 job at a time but the api can handle an array of jobs. We send an array ($container) of 1 job basically.
		$jobs = array();
		$container = array();
		$container[] = $this;
		$jobs['jobs'] = $container;
 
		return json_encode($jobs);
 
	}
 
 
}
