I have been trying to create a custom field using the following xml data, as mentioned in the following link link using this soap endpoint url
https://na1.salesforce.com/services/Soap/c/25.0
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Header>
<ns1:SessionHeader soapenv:mustUnderstand="0" xmlns:ns1="http://soap.sforce.com/2006/04/metadata">
<ns1:sessionId>00D28000000aTBh!ARwAQOkpYbkSeGeSSgdY0H9z3OEIoDSV_uWzqBV9.DSCK87HZjQoRDPIhoQx.OU1Z.6yDxqlf3kFGPB4yYHUUe.oUbN5baD8</ns1:sessionId>
</ns1:SessionHeader>
</soapenv:Header>
<soapenv:Body>
<create xmlns="http://soap.sforce.com/2006/04/metadata">
<metadata xsi:type="ns2:CustomField" xmlns:ns2="http://soap.sforce.com/2006/04/metadata">
<fullName>sampleco__c.samplecf__c</fullName>
<label>samplecf</label>
<length>100</length>
<type>Text</type>
</metadata>
</create>
</soapenv:Body>
</soapenv:Envelope>
with the following error response:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<soapenv:Fault>
<faultcode>soapenv:Client</faultcode>
<faultstring>No operation available for request {http://soap.sforce.com/2006/04/metadata}create</faultstring>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>
My guess is the endpoint url is wrong. Can anyone help me out on providing the correct endpoint url for metadata calls or am i missing anything?
