Subscription button transaction status.

[Shailendrabeyon]

Hello,

I am using subscription button on my website and its working perfectly .

I am using PDT for get Payment detail. I read the PayPal developer document. 

I have a question.

How many transaction status possible (like complete, pending..)  in case of using subscription button.

Because I read the IPN document and in case of IPN possible different status.

Thanks
