In app billing issue.

Dear Friends.

I just purchase an unity 3d plugin for In app billing android. I am so confused about the. i dont know how to do it.

I also set up the Product on google play console. here is the code :

var key "......................"; // my public key
IABAndroid.init( key );

IABAndroid.purchaseProduct("android.test.purchased", "my magical payload of extra data" ); // confused about this line


thank

 

Which plugin is it? and does it have documentation?

 

i am using prime 31 plugin. the documentation is so high level. i want some tutorials.
