MasterCard and Visa WebService

I have investigated PayPal, VeriSign, and CyberCash for a WebService
to verify payments. I would like to know if anyone has any other suggestions. I want to create a link to the web service with the information they request about a payment and receive confirmation
from them that the customer is verified. I would like this process
as simple as possible.

Thanks for your help.

 

VeriSign's Payflow Pro and CyberCash both require a DLL to be installed on the server. Since these are industry leaders for credit card processing, does discountASP.net have them installed?

 

I have just started researching the same things. For a smaller amount of transactions I'm leaning towards paypal. I personally put price over my ease of setup as an admin, and paypal has both. Probably if your doing $5,000+/yr in online sales then verisign would be the better bet. Just looked to expensive to me for under a few thousand in online transactions per year.

 

I am on the same boat of trying to implement Paypal credit card transaction for our website. I greatly appreciate if you could please let me know how you have implented Paypal on your websitehosted onDASP. Can you post the link too..Does itneed any prerequisites to be available on DASP?I have visited Paypal website to learn more but it would be more helpful if I can get hints fromsomeone whohas already/ practically implemented it on DASP.

Thanks

I have successfully used the PayPal development starter kit code on DASP. It's standard C# and ASP.NET.

I am busy thedevloping a site using Paypal on DASP and the integration is reallyeasy using the buy-now and shopping cart code. I dont have a link yet as everything is still under devlelopment but I cannot see any problems with it.


In addition they have the sandbox feature onder the Paypal developer center which is really great for testing without affecting live accounts.


I am just in the process of writing the IPN page to update my database (and send out reg codes)when succesful payments are cofirmed from Paypal and I musts say everything looks really easy, there is also example code on the merchant tools section of the site.


PAYPAL also now do not require customers to sign-up before paying (as they use to have to do) which makes it even better for reaching a wider customer base.


Also for small bussinesses starting off it is great that you do not need a merchant account at first so this saves on the initital capital required to get started.

 

I appreciate if you could you please post the links for buy now and shopping cart code from paypal thatyou are using or provide the links on paypal.





Thanks

Hi Kum,

Paypal has the tools to generate the HTML code you need on the site. Here is how to get there :

• Ensure you have a premier or Business account, you cannot accept payment with a personal account.
• Log in to your account.
• Click on the "Merchant Tools" tab
• Find the section "Accepting Website Payments"
• There a few links under that section including the "Buy Now Button" and the "Shopping Cart"
• Click on the required one.
• Fill in the fields i.e. Item Number, Description, Price, Button Style etc.
• Click "Add more options" if you want to customise it more.
• When you are done click "Generate Button"
• A text box with the correct HTML code for the button (and/or cart buttons) will appear this code will be set for your account, including Account name , item number etc.
• Cut and paste this code into the HTML for your web page.
• Test and test again.

Remember that you can sign up for the "Paypal Developers Central" that you can use to test payments without affecting any account, money etc. Go to https://developer.paypal.com/to sign up or log in. It is exactly like the real Paypal so all the same links apply. You must just set up some test accounts and use thosefor your test, The "buy now" and "SAhopping cart" links will also generate code for the est accounts.


I can't really post the code I use as it is different for each account - it has your account id etc. in it. It is easy to use once you get that link but shout if you have any problems.


I hope this helps you..


Cheers

Just wondering as this is somewhat unclear for me. If I decide to go with paypal myself do I need to setup any encryption with dasp? I know you can have encrypted buttons to make things more secure but that requires me to pay for a certificate and have it setup for my website, correct? If thats true, are there any other benefits to setting up a site certificate if i go with paypal or does it not matter?

thanks

 

Hi Jason,


You dont have to use any encryption for Paypal Buy Now buttons at all to get it working. Encrypting it however deters people from copying, modifying and using the code for dishonest transactions like changing an itemsprice to a smaller amount and then processing the payment. Your IPN code should anyway check for any changes to price etc. and only send out goods/codes if the price is not changed.


I have not yet implemented the encryption on my site myself (I am planning to do so shortly) but as far as I understand you can either :

• Enrypt the form data usingyour ownprivate certificate, in which case you must install/upload the certificate to PAYPAL to use to decrypt the data and then you use the certificate to encrypt the form data you will send.
• You can also just use the PAYPAL public certificate to encrypt the data, this is of course less secure as anyone can get this certificate for decryption and re-encryption.

A good example of the second option is used when you create a button from the PAYPAL site using their Buy-Now Button generator page and specifying that you want it encrypted. When you look at it, the resulting HTML code is encrypted (using the PAYPAL public certificate) and it can be used directly on any website, even from a local file,regardless of whether you have any certificates installed.


In either case you do not need to configure the certificates on DASP - The only time you will require to do that is if you want to run your site as a secure site (https).


One irritating thing is that with PAYPAL you can specify a custom image to use on the payment page but if this image does not reside on a secure site the users gets a warning message, I wish PAYPAL would let us rather upload our images and use them from there - anyway... this is the only reason I may consider buying a certificate.


I will be doing a bit more research into the use of the Paypal certificates in the next few days and will keep you updated.


I hope this Helps,


Reactor.

 

Forgive me, how can I include this component in my ASP.NET project?
