## Required information

Obtain the following information from the POIS operator:
+ The *POIS server endpoint*. This is the URL of the POIS server that MediaLive will send events to. The URL must be reachable by MediaLive.
+ The *Acquisition point identity* and the *Zone identity* (optional). These two fields ensure that MediaLive and the POIS server have a common identifier for the channel.
+ POIS endpoint credentials, if the POIS server requires credentials.
