Couple of issues I'm hoping the community can shed some light on here...
It seems impossible to customize the "Description" that appears in the payment review screen - It always shows the primary receiver's name. I have used the SetPaymentOptions call and that does not do anything useful.
I have found that the embedded flow URL will show the details (sort of...you have to expand the details), however the receiver's name(s) will be shown above each of the detailed items. I guess this makes sense, but it would be nice on the non-embedded flow method to be able to customize this "Description"...anyone have any experience here?
Second is the fact that it seems you can't get the details (shipping address) even if you request that the you force the user to enter a shipping address.
I have not been able to find a way to retrieve the user's address after the payment has been authorized using adaptive payments. Again anyone have experience here to say it can or can't be done?
Thanks all...
I could be wrong, but I think you can only set the item name? Via, SetPaymentOptions - like so:
receiverOptions.invoiceData.item(0).name=ITEM1 TITLE (or desc)
That being said - I'm not having a huge amount of luck getting the SetPaymentOptions function to work for me (no errors, but it just doesn't seem to apply the changes I'm passing it)
UPDATE - I just came across this setting for SetPaymentOptions - hopefully that helps:
ReceiverOptions - description - xs:string

I am hoping someone here can help me as I have been on to PayPal technical support who haven't been very helpful.
I am integrating PayPal checkout, following the instructions here: https://developer.paypal.com/docs/checkout/standard/integrate/
I wish to collect the paypal transaction ID in my database, send order confirmation emails etc... so as such I need to implement the optional step 5 described in this integration guide, which essentially means creating two routes on my server, one to call "create order" and one to call "capture order" - as per the sample code here: https://developer.paypal.com/demo/checkout/#/pattern/server
I have got this working successfully however I wish to know 2 things:
How can I see the 3D Secure flow - PayPal tell me know to worry about it as they handle it within the popup window but I would like to see the flow. I have tried test cards that should invoke the 3DS flow but they dont show any 3DS flow, just complete the payment.
The response to the capture order end point can return multiple statuses (COMPLETED, APPROVED, VOIDED, PAYER_ACTION_REQUIRED etc). Is it only the "COMPLETED" status that means a fully completed payment (and therefore I should complete the order)? What happens if it returns "PAYER_ACTION_REQUIRED" - which means 3DS check needed - will PayPal handle this and then re-execute my route?
Any help or advice would be greatly appreciated.
For the normal, 'Standard' integration, you don't have to test 3DS. The PayPal page/iframe already takes care of everything about it.
[Only for the 'Advanced' integration -- where you are implementing individual hosted card fields with your own styling -- do you need to implement and test 3DS yourself]
PAYER_ACTION_REQUIRED only happens with Advanced. All you need to do on the server end after the capture is check for COMPLETED and the existence of the Capture Id you're going to store for accounting purposes.
I'm using ASP.Net Membership Provider for logging into the premium content of this web site. The content isn't downloads, it's web pages of information and discounts, etc. That part is done. We want them to also have a PayPal Subscription annual payment to see the premium content. I would like ASP Membership and PayPal Subscription to work together as much as possible, but for the minimum I am thinking they will have to create a MemberId before they pay. Then I will send that MemberId to PayPal to associate the two.
I think I can do that like this:
Set "Auto Return" on in the interface so that it will redirect to return URL when payment is made.
Set "return URL" query string to MemberId. This requires not using the precompiled "Saved" buttons. I'll have to set it in Code Behind with Name Value Pairs, "NVP" to PayPal. I was hoping to just paste the stupid button.
But then, there were those "Advanced Variables" in the Button maker. Problem was they are compiled into the Saved button, so I can't change them for each person. But maybe that one parameter could be separate from the compiled parameters? Is this better than hacking the return URL? Are "Advanced Variables" good for anything?
All the details about the transaction will be POSTed to the return URL if I put in the right code, which might be rm=2. (Right?) Then I can record it.
This process is said to be unreliable, though, and PayPal recommends using a secondary system that they have, "IPN". PayPal sends the transaction details to me. I send them back http 200 code. Then I send it back to them in the same order I got it. Then they send me http 200. Then we all know it's good. This sounds like a few hours research to me, but if you've already done it once, it sounds like copy and paste. I hate reinventing the wheel. Is there a .Net sample of this IPN handshake/dance?
Also, if I do the IPN thing, maybe I don't need Auto Return. Maybe I add MemberId to "notify" URL instead of "return" URL. Then PayPal can handle the confirmation page, email, etc. Is that better?
Assuming we get the Subscription paid for and recorded with the MemberId, at least once per user session, after they log in, I have to check if they have paid their PayPal subscription and if it's up to date. "GetRecurringPaymentsProfileDetails" does this, but it is an API operation. That makes sense, but I was hoping to avoid learning their REST API. (Is there a "NVP" version?)
REST API OAUTH tokens expire every few minutes, but the only way it tells to get one is by using "Bash" to "cURL" some Linux commands. Again, this seems like the kind of thing that would only ever have to be written once. Does this already exist as a sample code somewhere?
(I don't want to use the API to do the Subscribe, because I don't want the Credit Card numbers to ever go to our site. Too much liability. That's why I wanted PayPal.)
Will this even work? I know PayPal has 18 ways to do everything and they all exclude each other, and I'm just getting the feeling that I'm creating a patchwork of unrelated ideas to fool myself into believing there's a light at the end of the tunnel. I've already been researching and experimenting for 10 hours or so. I really thought, going in, I'd just be pasting a stupid button.
If you want to just "copy the stupid button" then you'll have to stick to Payments Standard, and then you'll be limited with what you can do. For example, you won't be able to use GetRecurringPaymentsProfileDetails for a standard subscription.
Instead, you'll need to use Express Checkout and / or Payments Pro. There is indeed an NVP API available for these, and there is also a SOAP/XML version. Details on those can be found here: https://developer.paypal.com/docs/classic/api/
Specifically, for Express Checkout, you'll want SetExpressCheckout, GetExpressCheckoutDetails, DoExpressCheckoutPayment, and CreateRecurringPaymentsProfile. Some of those calls are optional depending on how exactly you're configuring things with the checkout flow.
For Payments Pro you'll use either DoDirectPayment / CreateRecurringPaymentsProfile or PayFlow depending on what version they put you on.
In any case, IPN is definitely the way to go for post-transaction processing.
.NET IPN Sample - https://github.com/paypal/ipn-code-samples/blob/master/paypal_ipn.asp
I'm using the callback API to prevent someone selecting a non-UK shipping address. I've supplied a callback url, I've set CALLBACKVERSION to 61.0.
When I go into the sandbox and choose an address I know the callback page is being called as I've added code to email me the values submitted to it and the value returned to PayPal. For anything with a SHIPTOCOUNTRY that isn't GB the response is
METHOD=CallbackResponse&NO_SHIPPING_OPTION_DETAILS=1
I've also tried setting a fuller response in case it doesn't like some required field to be missing
METHOD=CallbackResponse&CURRENCYCODE=GBP&L_SHIPPINGOPTIONNAME0=Standard&L_SHIPPINGALABEL0=Standard&L_SHIPPINGAMOUNT0=2.95&L_SHIPPINGOPTIONISDEFAULT0=true&L_SHIPPINGOPTIONNAME1=Express&L_SHIPPINGALABEL1=Express&L_SHIPPINGAMOUNT1=5.95&L_SHIPPINGOPTIONISDEFAULT1=false&NO_SHIPPING_OPTION_DETAILS=1
But it's still allowing non-UK addresses and just using the shipping options set during the initial set up request.
Any suggestions on where I'm going wrong?
After opening a ticket as suggested by PayPal_Patrick the problem was that I was adding the callbackversion in the wrong place. The full response to reject a shipping address on callback is:
METHOD=CallbackResponse&NO_SHIPPING_OPTION_DETAILS=1&CALLBACKVERSION=61
There are different transaction ID's for Buyer and Seller accounts.
I think this might be an issue caused by the country associated with the buyer account being used. I'm going to reach out to the product team for Express Checkout and see if it is intended functionality or not - I don't believe it would be.
If you want to stay updated on the issue I would recommend creating a ticket to PayPal.com/mts, give me the ticket number, I'll grab it and keep you involved.
Paypal provides access to a parameter called "SoftDescriptor" in a number of their payment request API calls, in the classic API (either NVP or SOAP). In theory, this parameter lets you send transaction-specific data along with your request, which will be passed along to the buyer's credit card statement.
This parameter is available on at least:
DoCapture
DoReferenceTransaction
DoExpressCheckoutPayment
I cannot, for the life of me, get this to work. None of these calls seem to set the softdescriptor for the initial descriptor (Which shows up in the bank statement while the charge is pending, before the payment posts). I've been waiting a few days for the payments to post to see if it will change at that point, but I'm skeptical.
Has anyone successfully used the SoftDescriptor? Did it require extra account setup?
This might be very late.
Soft Descriptors is supported only for US,UK and CA merchants.
Your account needs to be enabled for Soft Descriptor.You can contact Businesss/Customer Support to get this enabled.

Sorry, I know this is an old post, but I was looking for the same answer to the same question and I thought I would share what I found.
You should be able to use the following link to move past this error. In my case, I had a comma after the wrong right curly brace. Just copy and paste the example, in the aforementioned link, and change the values to meet your needs.
And I am about to post my own question about why the transaction amount is considered invalid
Is there any way to set the language of the errors returned by PayPal when processing a Direct Payment API call?
I've tried with:
LOCALECODE=es_US
to show them in spanish, but no luck. I called PayPal Support and the person said he didn't know, that I should ask in the forums ?!?!?
Anyone knows how to do this?
PayPal is not going to return the error message back in the selected language for the buyer. If you are wanting language specific errors, you would need to create your own database. Then based on the country, and the error number that is returned you can display the correct error message in that particular language.
You are probably looking for this , or at least I think that the person to whom you were talking was suggesting this kind of approach.
Remember that you are handling moneys and payments here, if you are not sure about what are you doing spend some months/years to refine your approach.
