Fix for post format from:

type=message&timestamp=2019-02-04+22%3A30%3A03&body=A1+5261LV+%3A+Booglaan+Vught+Obj%3A+bij+reinier+van+arkel+Rit%3A+14468&capcodes=001120105

to:

Array
(
    [payload] => {
    "body": "A1 13106 Rit 14876 Diemen Albert Loethoelistraat 1111KW",
    "capcodes": [
        "002029568",
        "000120999",
        "000120106"
    ],
    "groupid": "07.093",
    "is_posted": false,
    "priority": 1,
    "receivers": "002029568, 000120999, 000120106",
    "sender": 3,
    "timereceived": 1549323037.1240869,
    "timestamp": "2019-02-04 23:30:37"
}
)

With PHP now you can use:

<?PHP
$data = json_decode($_POST['payload']);
