For version 2 calls, use the following format in the REST API request header:

<METHOD> <serverUrl>/<URI> HTTP/<HTTP version>
Content-Type: application/<json | xml> 
Accept: application/<json | xml>
icSessionId: <SessionId>

For version 3 calls, use the following format in the REST API request header:

<METHOD> <baseApiUrl>/<URI> HTTP/<HTTP version>
Content-Type: application/json 
Accept: application/json
INFA-SESSION-ID: <SessionId>

Note that if you use a tool such as Postman, requests automatically include the HTTP version. If you enter the HTTP version in the URL, the request is not successful because the HTTP version occurs twice in the URL.
