Hi all, I'm trying to use the ISP Config API from python, since I'm not that familiar with PHP. Since there is no WSDL I'm facing issues in building the correct request payload: Code: <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/1999/XMLSchema" > <SOAP-ENV:Body> <mail_blacklist_add SOAP-ENC:root="1"> <v1 xsi:type="xsd:string">{sessiond_id}</v1> <v2> <access xsi:type="xsd:string">REJECT</access> <source xsi:type="xsd:string">51.68.127.0</source> <server_id xsi:type="xsd:int">1</server_id> <type xsi:type="xsd:string">client</type> <active xsi:type="xsd:string">y</active> </v2> </mail_blacklist_add> </SOAP-ENV:Body> </SOAP-ENV:Envelope> I'm receiving: Code: <faultcode>database_error</faultcode><faultstring>Column 'server_id' cannot be null INSERT INTO `mail_access` (`server_id`, `source`, `access`, `type`, `active`, `sys_userid`, `sys_groupid`, `sys_perm_user`, `sys_perm_group`, `sys_perm_other`) VALUES (NULL, NULL, NULL, NULL, 'n', '2', '2', 'riud', 'riud', '')</faultstring> Does somebody has a working example of the payload? Thanks a lot.
