Question

Hi all i using cumulocity api with php , is all ready. I have problem with get event/events by deviceId.

$url = 'https://*********.iot.a1.digital/event/events?dateFrom=' . $date . 'T' . $timeNew . '.000Z&pageSize=1000&type=lwm2m_log';


$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
// curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Acept: application/vnd.com.nsn.cumulocity.operation+json',
));

curl_setopt($ch, CURLOPT_USERPWD, "$login:$password");
$result = curl_exec($ch);
curl_close($ch);

How to create url get by deviceId

Answer 1

To query events (or other data types) by source device ID, please use the query parameter "source" instead. See https://cumulocity.com/guides/reference/events/#events-api

Your query should look like this:

https://********_live.iot.a1.digital/event/events?dateFrom=2020-08-28T14:02:07.000Z&pageSize=1000&type=lwm2m_log&source=1234567
