How do I use Interstitial prizes?

[CyclopDroid]

In my new game, I want to give a free currency, though sene loses in the game, only if the user is viewing a video.
I saw that, in creating an AdMob ad, there are Interstitial Rewarded.
Once created, how they fit into the project? They use it like any AdMob, oppre there is another procedure? You have to download new libraries?
Someone has used? If you can show the source code?
Thank you.

In general, you show rewarded ads (exactly it's video) to user, after they watch it you will reward them something (life/coin...).
I think you should use ad mediation like Appodeal or AdToApp. They provide SDK and B4A plugin, they calculate price of ads automatically, you just need to add some code to show rewarded ads and code to reward users when they watched it.
