This section contains information on common problems which can occur when creating a client software.
Invalid access point
You are receiving HTTP error with code 403 and description 'Only XML-RPC or SIP requests are allowed on the port 7050'. This means that you are using invalid access point, please use correct access points:
https://ka.demo.plesk.com:7050(for testing purposes)
Compare the signature (struct, struct, string, string, string) in the error message with those available in the documentation. Probably, you have missed one parameter or a parameter has the wrong type. E.g., a list of upgrade plans in partner10.createKey() method is an array, even if you have only one upgrade plan, you still need to send it as a 1-element array.
Not valid XML
You are receiving HTTP error with code 400 and description 'Unable to parse XML-RPC request'. This happens when XML syntax is incorrect. This often happens when an XML-RPC request was manually created instead of using proper libraries for your programming language.
