Why do we have to repeat the fields like L_PAYMENTREQUEST_0_NAME0 or L_PAYMENTREQUEST_0_DESC0 or PAYMENTREQUEST_0_DESC or even PAYMENTREQUEST_0_AMT in DoExpressCheckoutPayment if we already set them in SetExpressCheckout? Shouldn't they be stored in the session that we've created in the first step?
SEC simply prepares the system for a checkout and gives you a token. Much could change between the SEC and the DECP call, so it's left up to DECP to finalize everything.
For example, with SEC you might pass a shipping address, but then during checkout the buyer changes it to one of their PayPal addresses. Then when you call GetExpressCheckoutDetails you'd get back this address, so then the system wouldn't know which one you wanted to actually include with the order. It would use whatever you pass into DECP.
Same with tax information, shipping, etc. which of course adjusts the final amount, too. Maybe you don't have any address during SEC so you have to wait for GECD to get an address and calculate shipping and tax based on that. Then the values for those parameters and the total would be different between SEC and DECP.
Those are just a couple of examples, but again, there are lots of things that could change between SEC and DECP depending on your application, so you just need to make sure that whatever you want to be included in the final payment details is included in DECP.

So i was integrating my app with paypal for express checkout and could not figure out how to add in my gst/hst number for Canada to the receipt.
it is mandatory if i am to charge taxes in Canadian shipment, that the gst/hst number be visible in the receipt, but cant seem to figure this out.
any help would be appreciated!
below is an example of my receipt but i want to add some additional content for the gst/hst number. where would i be able to and how.

ANSWER:
so this is just a trick around it since i couldnt find a proper solution, but i just add in another item with the GST/HST Number. i leave the cost of it to 0 so it does not affect the total price but the buyer is still able to get the gst/hst number on their receipt.
The amount key can include a breakdown key, which is an object of type amount_breakdown documented here: https://developer.paypal.com/docs/api/orders/v2/#definition-amount_breakdown
tax_total is the key name of one of the objects you can include in the breakdown.
The breakdown's subtotals must add up to the actual amount value.
I have two testnet nodes set up at home.
I'm testing sending between them, all communication is working just fine!
I just tried to send 0.0003 from A->B
This is my tx:
https://live.blockcypher.com/btc-testnet/tx/dc7a9ba7e01efe04ae6b757d1832d4287b95105f6a1e88eb314a926919d1c32b/
I used sendtoaddress and set the receiver to charge the fees. (5th argument set to true)
I'd created a new address: 2N8yYvrbAxKm9nhS8fDCZng1GRVwvxhUy8n
on Server B seconds before using that new address to send from A->B
How can I find out more about why I was charged
0.01010081 BTC to 2N3HvqWY8sQ59mqHDXeWAd6tV8LWR7pmNnY
I assume this is the wallet of the node that validated the transaction?
I'm using jsonRPC and here is my call:
sendtoaddress(
'2N8yYvrbAxKm9nhS8fDCZng1GRVwvxhUy8n',
'0.0003',
'test from local to MT',
'Message for MT to see?',
true
)
rawtransactions confuse me I'll be honest.
I'm assuming that I need to get over that, but before I do, why was I charged a fee many 100% higher than my transaction?
Cheers!
The output to 2N3HvqWY8sQ59mqHDXeWAd6tV8LWR7pmNnY is your change.
Bitcoin tracks money in a way similar to physical cash. Your balance is composed of many individual outputs, each of a specific value, similar to how your physical wallet balance is composed of many individual notes, each of a specific value (for example, someone with $25 in their wallet might have $20 + $5 in notes).
When you spend Bitcoin, you must consume an existing output in full. As it is uncommon for someone to have outputs that sum up precisely to their desired send amount + fees, any left over value from the outputs used by the transactions are returned to an address in your sending wallet as change.
I have experienced a problem similar to this question, while trying to make my discounts work with SetExpressCheckout.
I've resolved to use the method the accepted answer's author suggests: creating an additional product named "discount" with a negative value.
This is not too bad, but I'm getting fed up to have to accommodate Paypal with all the changes I make on my cart, and basically send the whole cart to Amazon when the customer has already had plenty of opportunities to check it while on my website and he now just wants to pay.
I would prefer to send the customer to a blank Paypal payment page, without the cart on the left.
Is this possible with Paypal Express Checkout? Any alternative?
If you go thru Paypal Express Checkout then it possible to give discount
(1) – Item name. The item name can identify this item to distinguish it from other line items in the order.
(2) – Item description. This field identifies which of several items the buyer is purchasing. For example, you may be offering an item in different sizes. Knowing the size helps the buyer decide whether the one they selected was appropriate. If the item is an eBay auction item, it is recommended that you provide the phrase "eBay item" in this field.
(3) – Item number. Each item can be further identified by an item number. If the item is an eBay auction item, it is recommended that you provide the eBay item number in this field.
(4) – Item unit price. This field specifies exactly how much one unit of the item costs. It can be a positive or negative value but not zero.
(5) – Item unit quantity. This field identifies the number of units the buyer is ordering. PayPal calculates the value in the Amount (6) column as the product of line-item unit price and line-item unit quantity. You can also show other detailed information about the order:
(7) – Item total and tax, which are the total of all items in the order and the tax, respectively.
(8) – Shipping and handling, which is the sum of the shipping and handling amounts.
Note: You must determine actual shipping and handling amounts.
(9) – Shipping discount. If the buyer is receiving a discount on shipping, the value appears as a credit in this field.
(10) – Insurance. This field shows the insurance fee when there is insurance on shipping.
(11) – Total. This is the total of the order, including shipping, handling, tax, and other price adjustment-related items.

NO, you can not send to the customer to a blank Paypal payment page, without the cart on the left. Because you can not say: I'm not selling anything and give me your money.
But alternative, you can do this way:
Change your coffee = $200 instead of $20 for total prize. And you don't need to list anything else after.
I have, in my opinion, pretty complex order case to implement. Paypal was choosen as a solution, but I can't figure it out how to implement it properly using express checkout (or anything else, but I am not sure what is proper to use).
Final order that can consist of (most complex example here):
subscription A with 1 month free trial - 100$/year
subscription B without free trial - 200$/year
initial payment for entire order - 50$
Requirements:
start of the whole order can be postponed due to some factors (I can set PROFILESTARTDATE to the given date)
all subscriptions in the order can be either monthly or yearly, so case where subscription A is paid per year and subscription B per month IS NOT ALLOWED
whole order must be processed in one paypal redirect (paypal page with products listed where client can login to confirm the order)
My problem:
in that order subscription A starts 1 month later than B but I can only set one PROFILESTARTDATE
I could use TRIAL*** parameters (like TRIALBILLINGPERIOD) for subscription B but I can only set one such parameter per paypal request for express checkout, so same problem as above
What would be a best option for such case ?
I am testing MIGS Virtual Payment Client on a test account. When I select payment, I am directed to the Payment Server page where I can choose between Visa and MasterCard. I have been given the following test data in the MIGS manual:
I use 123 as CSC value. However, the transaction always fail with
vpc_VerStatus=E
vpc_TxnResponseCode=2
vpc_Message=Declined //for Visa
vpc_Message=The+card+holder+was+not+authorised.+This+is+used+in+3-D+Secure+Authentication. //for MasterCard
By the way, if I select MasterCard, I am prompted "Please enter your OSID or the last 5 digits of your NAB ID" and a Credit Limit. I use OSID with value 123456 and Credit Limit 10000 respectively. (These are values I entered by myself as I was not given information what to input there).
I had a look at this Commonwealth bank and MIGS Virtual Payment Client error code but it does not solve my problem.
Any help why the transaction is being declined?
Okay, there's a handful of things here you need to understand/check out.
1. Ensure the transaction value ends in $xyz.00 or it will always decline
MIGS behaves differently in TEST and PROD. In TEST, MIGS uses the "cents" portion of your test transactions to determine what response code to return, NOT whether you have correctly provided the necessary data for the transaction. These cents values are as follows:
$ XXX.00 returns "0 Transaction approved"
$ XXX.10 returns "1 Transaction could not be processed"
$ XXX.05 returns "2 Transaction declined - contact issuing bank"
$ XXX.68 returns "3 No reply from Processing Host"
$ XXX.33 returns "4 Card has expired"
$ XXX.51 returns "5 Insufficient credit"
2. Disable 3-D Secure
It looks like you're also getting caught by 3DSECURE, also known as "Verified by Visa" and "Mastercard SecureCode". Call your acquirer/bank and ask them to disable this in TEST and Prod. Why? Invariably when this goes live, your customers will see a screen they are not expecting that asks for more information and then either pick up the phone and ask you to "fix it" or (even worse) leave your store thinking it's fraud.
Because 3-D secure has such low takeup, even most bank support staff don't know about it. Just today I had one of my clients call me about this "issue". One of their customers had called their card issuer to enquire as to what this "Verified by Visa" screen was. The bank (a major Australian bank) helpfully told them it was probably fraud and to not buy anything from that site.
3-D secure has such low penetration in Australia I'd suggest the only outcome of having it enabled is to reduce sales. Don't use it.
