Question

I need to create a recurring payment that should process only twice. First, I need to get an advance amount and remaining amount should be payed in another date. Now, I would like to have the time reduces according to the initial payment date.

For instance, assume user purchases today then recurring will be set for 60 days, if user purchases tomorrow then it will charge in 59 days, then day after will be 58 days.

How to proceed with this?

Thanks for your time!

Answer 1

Edit: I was thinking of adding this info earlier but was not sure about your question. What you mean is also(?) called as Direct Debit. I have worked on a similar project. We charge the installments to their Bank Account and it entirely depends on your Payment Gateway how to implement it in your application.

You don t have to worry about storing their bank details. Payment gateway will take care of future payment processing. If you still need CC then you will have to speak to your payment gateway provider. Payment gateays differ from country to country. I have worked with mCheck & ICICI (India) and BTBuynet and Logic Group (UK). Let me know if you need more info.

To do this first you will need a start date.

So if startDate is 01/12/2009 and if I make a purchase today then then next payment processing date will be

(60 - (TodaysDate - StartDate))

Is this that difficult? Or I didn t understand your question?

Firstly, you will need a Payment Gateway that supports recurring payments, such as protx.

Once you have that set up, they will provide you with an API, usually based on a web portal, which you can use to set up and take recurring payments.

In your code when you are processing payment, you simply pass the required variables through in the post to the web address protx provide you and they will handle the set up and retrieval of funds.

Paypal also support recurring payments.
