How i can use curl payload to submit my file?

I don't know why you expect us to debug this using only headers when the problem is possibly in your code. Check out the MVCE page on what would help your question along — Machavity♦
i have to observe from headers and request payload that what parameter should i sent ? this is post request and i did not observed form parameters — Awais Mushtaq
I have observed that there are no parameters in post request to that API Wrong, there's a bunch of parameters, to name a few: Cookie:s, lat_lon, __utmt, _mystore2_session, __utma , AND MORE — hanshenrik

Also, that's not the complete request header you're showing us. for one, it's missing the request type (though its probably a POST request) anyway, to replicate this with curl, it's something like:

<?php 
$ch=curl_init();
curl_setopt_array($ch,array(
CURLOPT_URL=>'???',
CURLOPT_ENCODING=>'',
CURLOPT_POST=>true,
CURLOPT_POSTFIELDS=>array(
'Cookie:s'=>'',
'lat_lon'=>'33.69&73.0551',
'_mystore2_session'=>'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--c3c1b5d437fd04a80dc888822811d2d4d354ae29',
'image'=>array(new CURLFile('/path/to/file.png','image/png','Screenshot (156).png'))
//and more post data here.

),
CURLOPT_HTTPHEADER=>array(
'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,/;q=0.8',
'Accept-Language: en-US,en;q=0.8',
'Cache-Control: no-cache',
'Pragma: no-cache',
'Origin: myURL',
//and more headers here
),
CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36',
));
curl_exec($ch);

note: this is NOT the complete code, it's missing a bunch of data for CURLOPT_POSTFIELD and CURLOPT_HTTPHEADER , but this should get you started
