Answer 1

Answers of your questions:

1) What attributes of response should i save in DB?

Answer: subscr_id,amount3, payer_email, payer_id, period3, auth These fields are stored into your DB

2) If i successfully done the payment i get a new row in my recurring payment dashboard. what will happen on the next recurring date? how can i handle that recurring process?

Answer: For this you have to create webhook, which automatically create request on the next recurring date ? Which acknowledge to you that you have to pay for next subscription.

3) not related to recurring but i want to skip the page of "Return to saller's site".

Answer: Not sure you have to use the account details when payment process occurred.

I hope answers are help you. Thanks
