Positions API String
You have to provide "Accept: application/json" header in the request. Otherwise it would return random format. In your case it's CSV.
Thank you, obvious really looking at code to long :-)
I am trying to use code below to get positions and I can use same ajax code format for get devices ok, but with positions I just get 400 Bad Request NullPointerException (... < DateUtil:65 < PositionResource:80 < ...)
What am I missing?

var to = "2017-04-05";
$.ajax({

headers: {
"Authorization": "Basic " + btoa("admin@xxxxxxx.com:jxxxxxx5")

deviceId:deviceId,

success: function (response) {
console.log(response);

I already explained what you are missing. I still don't see "Accept" header anywhere in your code.
I have managed to get the positions in the correct format with using ajax, but still face the same issue with cURL being returned as csv. Using the same script I am able to get devices as json but positions will not. Below is script I have implemented taken from one of the blog posts. I just cannot work out why it will not return as json data and only returns csv.
I thank you in advance for your time and patients.

It seems like you are completely ignoring my messages. Why are you even asking on the forum if you are not planning to listen to the answers?
I am not ignoring your answer I am trying to understand why it works ok with get device as json but not positions I would have presumed If accept was not included it would also get devices returned as CSV and not as JSON.
If you don't explicitly provide "Accept" header, the result is undefined. You will randomly get JSON or CSV.
Thank you for clarification I did not realise it was a random return.
I am using
$positions=traccar::positions($deviceId,$from,$to,$cookie);to get the positions and using$positions->responseget returned a data as below.My question is how can I pull data from this response string like latitude or longitude, I was expecting an array or json.
