Access

In order to access API, you will need to pass the following two headers for each call.

Authentication and authorization stand on protocol layer using basic HTTP authentication. Given username and password with separator “:” MUST be base64-encoded and passed as HTTP header “Authorization”. This header is mandatory for all requests. For example, if "TestLogin" set as the username and "TestPass" set as the password, then the field's value is base64-encoding of TestLogin: TestPass, or QWxhZGRpbjpPcGVuU2VzYW1l. Then the Authorization header will appear as Authorization: Basic QWxhZGRpbjpPcGVuU2VzYW1l

Header 'Content-Type: text/xml'
