Some users might get confused when seeing the soap XML request format. Like they use SOAPAction URL value as request action or don’t get the header parameters. In this tutorial, we are going to clear your confusion.

Let’s see how soap envelope XML look like.

Soap Envelope XML Request Format is like that:

POST/webserviceexternal/contracts.asmx HTTP/1.1

Host:example.com

Content-Type:text/xml;charset=utf-8

Content-Length: length

SOAPAction:"http://example.com/CreateItems"

xml version="1.0"encoding="utf-8"?>

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:xsd="http://www.w3.org/2001/XMLSchema"

xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">

<soap:Body>

<Login>string</Login>

<Password>string</Password>

</extLoginData>

<Item>

<Description>string</Description>

<InventoryMethod>string</InventoryMethod>

</Item>

</Items>

<warnings xmlns="http://www.JOI.com/schemas/ViaSub.WMS/">string</warnings>

</soap:Body>

</soap:Envelope>

As you see above Host, Content-Type, Content-Length, and SoapAction, all are the header parameters.

And right below is the XML request string you need to pass. Make sure you put the right value in XML parameter element.

We can post soap XML using curl method. Define the curl request header and post the soap envelop XML data. Check the below code to execute this request.

$xml_post_string='xml version="1.0"encoding="utf-8"?>

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"

xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">

<soap:Body>

<Password>password</Password>

</extLoginData>

<Item>

<Description>sample item</Description>

</Item>

</Items>

<warnings xmlns="http://www.JOI.com/schemas/ViaSub.WMS/">string</warnings>

</soap:Body>

</soap:Envelope>';

$headers = array(

"Content-Type: text/xml; charset=utf-8",

"Host: example.com",

"Content-length: ".strlen($xml_post_string),

"SOAPAction: http://example.com/CreateItems"

);

$url = 'https://secure-example.com/sample/contracts.asmx?op=CreateItems'; // WSDL web service url for request method/function

$ch =curl_init();

curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,0);

curl_setopt($ch,CURLOPT_URL,$url);

curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);

curl_setopt($ch,CURLOPT_TIMEOUT,10);

curl_setopt($ch, CURLOPT_POST,true);

curl_setopt($ch,CURLOPT_POSTFIELDS,$xml_post_string);// the SOAP request

curl_setopt($ch, CURLOPT_HTTPHEADER,$headers);

echo$response=curl_exec($ch);

curl_close($ch)

You need to change SOAPaction and request URL as per soap envelop request pattern and call method this curl method in PHP. This is quite easy to implement this soap api call.
