Also - some of you are interested in being able to add item detail to the Payment request - in order to add 1 or more items to the PayPalPayment manifest - and - it does look cleaner and more professional to the buyer.

Here's a quick tutorial to add items to your payPal Manifest:(be SURE TO BACKUP your project before you make significant changes like this - just in case):

1. First - Change your PayPalPayment Service (that's what I called it in the original tutorial above). Here's how you adapt what you already have - into what's required....Remember - you are changing the "REQUEST" tab (not the response please).

   

   2.Next - Map data into the new fields on the request. In this example - I'm adding only 1 item to the Payment Request (you can obviously have multiple items - but you would ADD those to an array of items - prior to execution of this mapping - and do that in Javascript - examples, sample code, etc. - upon request .... again that's a bit more significant piece of work - and it requires some coaching from me that I cannot deliver here in this post. You're up to it though I know it!!!)

   Here's an example mapping for a single item (to the new fields in the request):

   

2. And Viola!!! PayPal responds by showing you the list of items on the left side of their Payment UI :

oh - and remember - none of this is rocket science.... I'm just developing the request by following along the documentation found on the PayPal developer - API Reference.

You can find that reference here - and make changes to any of your request - responses - by following the reference guide..... easy peasy....!!!

Hello,

We have published Using PayPal API plugin tutorial, you can find it here https://devcenter.appery.io/documenta...

for anyone that continues to follow this thread - and has created a service as I chose to above - with the name "PayPalGetToken" - please change the name of this service to Pay_Pal_Make_Key - GetToken appears to be a reserved word somewhere (Chrome for Windows for sure) and on other platforms.

It caused me a few headaches (errors I could not make sense of or debug) when I was publishing my site where I used this service with this name.

Best,

Bruce

Hello Bruce, if you get a chance, I sent you an e-mail this morning. I of course have run into some problems.

Glad they are fixed now!

Hi Bruce, the PayPal integration works fine for me in the Appery test environment. However it fails on the phone at the approvement stage; i.e. when the return url is called from PayPal. I don't receive details of the payment. Any ideas what the issue could be?

Yes .... On browsers other than the desktop ... PayPal wipes out local storage so you can't execute your saved transaction information.

Save it to a collection data store prior to calling paypal and then know I the way back you've got to start all over again with your local storage. ( read it from the collection ... Log in again etc.)

Hi Bruce, on the phone its alll of a sudden going back to the appery page when the payment is approved this doesn't happen in the browser. Any idea why this is happening?

Yes - exactly what I stated - when you go to the PayPal website from your inApp browser - PayPal does you the 'favor' of clearing all of your localStorage.

When you come back from PayPal then - you will find that your event to 'process the payment' fails - and unless you have error handling in the event to display the error - it will take you back to the Appery page.

I can help with the issue (i've written code around it) . Bottom line there are two solutions:

1. Implement the solution I refer to above - save all of your important memvars before calling payPal website and then upcoming coming back from PayPal - you need to login again, and read back restore the memvars - all before processing the paypal payment. This can be a real pain in the keester ... however, I have it working in an instance that I have and one for a client (a member of the forum here). unfortunately at this time - I don't have the cycles to post it here as I'm working another project for another member as well as a full time gig.

2. You can collect credit card details on your side --- and then call the PayPal API using the credit card details already collected. I have not done that yet - but that's the path I recommend going down long term. It's better for the users (you don't leave your app which users hate) - and you get a response without having to leave the app. However, this is undocumented ground here on this forum - and will take some technical chops to pull off and there is a separate payPal approval process for this ---- its reasonably light weight - and you generally get approved in a couple of days.

   You might want to look at the other plugin - Stripe - I believe appery just did a tutorial on it...

   Best,
   Bruce
