Hello friends,

Probably you have read your part 2.

then today, I continue to introduce to you part 3, use Chatfuel to look up gas prices offline.

Come on, let’s get started

As with parts 1 and 2, the setup is quite simple. You go to the Automate menu, create a block called Gasoline Prices, in this tutorial I do with gasoline price lookup

Then you set up in the block is a JSON API like part 1, only we now change the URL.

You use the code below and use it for your hosting, here I code in PHP

&lt;?php
header('Content-Type: text/html; charset=utf-8');
$url         = 'http://www.petrolimex.com.vn/';
$content     = file_get_contents($url);
$first_step  = explode('&lt;div id="vie_p6_PortletContent"&gt;', $content);
$second_step = explode("&lt;/div&gt;", $first_step[1]);

// "Xăng 95 IV: &lt;br /&gt;";
$xang_95_4_v1 = strip_tags($second_step[4]);
$xang_95_4_v2 = strip_tags($second_step[5]);

// "Xăng 95 III &lt;br /&gt;";
$xang_95_3_v1 = strip_tags($second_step[8]);
$xang_95_3_v2 = strip_tags($second_step[9]);

// "Xăng 95 II &lt;br /&gt;";
$xang_95_2_v1 = strip_tags($second_step[12]);
$xang_95_2_v2 = strip_tags($second_step[13]);

// "E5 RON 92-II &lt;br /&gt;";
$xang_92_2_v1 = strip_tags($second_step[16]);
$xang_92_2_v2 = strip_tags($second_step[17]);

// "DO 0,05S &lt;br /&gt;";
$xang_do_v1 = strip_tags($second_step[20]);
$xang_do_v2 = strip_tags($second_step[21]);
// "Dầu hỏa &lt;br /&gt;";
$dauhoa_v1  = strip_tags($second_step[24]);
$dauhoa_v2  = strip_tags($second_step[25]);
