Unable to create listview using metadata api on Salesforce - soap

Question

I am new to Salesforce metadata api. I want to create a listview of contacts on Salesforce using metadata api.
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:met="http://soap.sforce.com/2006/04/metadata">
<soap:Header>
<met:AllOrNoneHeader>
<met:allOrNone>false</met:allOrNone>
</met:AllOrNoneHeader>
<met:CallOptions>
<met:client>https://xyz.salesforce.com</met:client>
</met:CallOptions>
<met:SessionHeader>
<met:sessionId>xyz</met:sessionId>
</met:SessionHeader>
</soap:Header>
<soap:Body>
<met:createMetadata>
<!--Zero or more repetitions:-->
<met:metadata>
<!--Optional:-->
<met:fullName>TESTVIEW__c</met:fullName>
</met:metadata>
</met:createMetadata>
</soap:Body>
</soap:Envelope>
I am getting
[
{
"errorCode": "METHOD_NOT_ALLOWED",
"message": "HTTP Method 'POST' not allowed. Allowed are HEAD,GET"
}
]
The endpoint I use is:
https://xyz.salesforce.com/services/data/v51.0/sobjects/Contact/listviews
I updated to SOAP endpoint:
https://xyz-dev-ed.my.salesforce.com/services/Soap/m/51.0/1112312DRED21
Now I am getting
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<soapenv:Fault>
<faultcode>soapenv:Client</faultcode>
<faultstring>content-type of the request should be text/xml</faultstring>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>
I guess I am one step closer. Is the payload valid for creation of contact listview?

You can't do a Metadata API deployment by making a POST to the REST API endpoint.
If you want to use a REST endpoint, use the REST deployRequest endpoint. If you want to use the SOAP createMetadata() call to which your payload appears to be oriented, you need to use the SOAP API.
