Parameter Required Description
apikey Yes Access code that authorizes your request for data from Rovi.
sig Yes A calculated authorization code. To perform the calculation, execute the MD5 function on the concatenation of the following three strings:
  • Your API key.
  • The secret key you received with your API key.
  • The Unix time. Unix time is a timestamp supported in most development environments, and is generally defined as the number of seconds since January 1, 1970 00:00:00 GMT.

Perform the calculation at the time of each request to be sure it's within a five-minute window of the server time. If you're testing the call in a browser, use our online signature generator to perform the calculation.
