Issue with WDSL Service - web-services

Question

I am trying to develop code to use a webservice. The documentation is here: https://app.foliosdigitalespac.com/CR33Test/ConexionRemota.svc. Specifically I want to use the method GenerarTicket.
If I use this tool and provide the link above I can generate an XML for this specific method. This is the generated XML.
<soapenv:Envelope

</tem:ticket>
</tem:GenerarTicket>
</soapenv:Body>
</soapenv:Envelope>
Then I can submit the request and it works as expected. If like to try this with Postman so I can write the PHP code.
I am sending a POST to https://app.foliosdigitalespac.com/CR33Test/ConexionRemota.svc?function_name=GenerarTicket with the Content-Type header set to text/xml and the above XML as a raw XML body. When I click submit I get the following error.
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>
<s:Fault>
<faultcode xmlns:a="http://schemas.microsoft.com/ws/2005/05/addressing/none">a:ActionNotSupported</faultcode>
<faultstring xml:lang="es-MX">The message with Action 'GenerarTicket' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).</faultstring>
</s:Fault>
</s:Body>
</s:Envelope>
Obviously I am not doing something well but cant figure what it is. I was told by the WDSL developer than I can send a POST with the correct information and get the response. Any help please?

Answer 1

I figured out what was going on. The correct URL is https://app.foliosdigitalespac.com/CR33Test/ConexionRemota.svc.
Then the SOAPAction header must be set to the correct Action. According to the documentation the Action is http://tempuri.org/IConexionRemota/GenerarTicket. I was using as the Action only GenerarTicket.
Since I wanted to use PHP the corresponding code is
<?php
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "https://app.foliosdigitalespac.com/CR33Test/ConexionRemota.svc",
