Hi !,

I am not able to add an estimate using the API with php. No error is shown too.

openssl :enabled.

my php code is as below.

Thanks in advance!

<?php

function do_post_request($url, $data, $optional_headers = null)

{

$params = array('http' => array('method' => 'POST','content' => $data));

if ($optional_headers !== null)

{

$params['http']['header'] = $optional_headers;

}

$ctx = stream_context_create($params);

$fp = @fopen($url, 'rb', false, $ctx);

if (!$fp)

{

echo "Problem with $url";

}

$response = @stream_get_contents($fp);

if ($response === false)

{

echo "Problem reading data from $url";

}

return $response;

}

$url = 'https://invoice.zoho.com/api/estimates/create?newFormat=1&authtoken=myauthtoken&scope=invoiceapi&apikey=myapikey';
