What to use to make a Paypal Payment in Windows Phone 8.1

Question

I need to make a simple paypal payment from my Windows Phone app. I used to use PayPal's Windows 8 SDK, but it has been discontinued so I can't even get the old SDK from the official github page (http://paypal.github.io/Windows8SDK/).

The other options seems to require an integration on a web page. I've tried looking at similar questions on S.O. but they're either outdated, or where before / while there still was the Windows 8 SDK, so they're not valid anymore.

Upon further inspection, it would seem the SOAP API don't work because importing them won't generate PayPalAPIAASoapBinding(same behaviour as a Console application, which I fixed importing an old Web Reference, which is not possible on WP) and REST APIs rely on Paypal nuGet package which can't be used in Windows Phone (https://developer.paypal.com/docs/api/).

I am currently at a loss for options (Except to set up an external website to do the job).

Answer 1

Having faced all the aforementioned problems (I still don't know why Paypal pulled the plug for Windows Phone support), I found a workaround.

• I generated a Paypal Buy Now button (https://www.paypal.com/uk/webapps/mpp/get-started-payment-buttons), the unencrypted & non account saved version.
• I copied the code in an html file within my app and used some markers on the hidden fields that interested me (description of the product, amount, shipping costs, etc.).
• From my previous page the user will select the product details he wants to purchase, such details will be passed to another page in which I have among other things a WebBrowser control.
• I will replace the markers with the details passed from the previous page and load the html in the WebBrowser.
• The user can then proceed with the purchase.

I am considering about making this into an open source plugin / library to make things easier for the fellow developers hit by my same issue, will update this with the link if I find the time to do so.
