I have a Redirect to take the buyer to the Paypal cart. The URL it forwards them to is (formatted for readability):
https://www.paypal.com/cgi-bin/webscr?cmd=_xclick
&business=email#domain.com
&pal=BGUR9WCWZAL7G
&button_subtype=services
&no_note=1
&no_shipping=1
&rm=1
&return=http://127.0.0.1/store/thank-you
&cancel_return=http://127.0.0.1/store/payment-cancelled
&shipping=0.00
&custom=LoggedInUser|45
¤cy_code=EUR
&item_name_1=Store 9 Item
&amount_1=12.00
&item_name_2=Something else
&amount_2=24.00
I can't use Post data for design reasons.
If I have it as a single item by passing &amount=1&item_name=5 Store Items it works fine, but I need to break it down into individual items if possible.
Is this do-able? I see this question:
Paying for multiple items (at once) via paypal
But it's for posting, not a url
You may want to try the cart upload method. See this page for more information.
It will basically turn out something like this:
https://www.paypal.com/cgi-bin/webscr?cmd=_cart
&business=email#domain.com
&pal=BGUR9WCWZAL7G
&button_subtype=services
&upload=1
&no_note=1
&rm=1
&return=http://127.0.0.1/store/thank-you
&cancel_return=http://127.0.0.1/store/payment-cancelled
¤cy_code=EUR
&item_name_1=Store 9 Item
&amount_1=12.00
&quantity_1=1
&shipping_1=0.00
&item_name_2=Something else
&amount_2=24.00
&quantity_2=1
&shipping_2=0.00

This seems a very naive set of questions, but I really couldn't find it.
Question 1) I am trying to implement IPN for PayPal. I want to enter The listener URL, but I couldn't find where. I've searched the internet and all the responses are old. Where could I put it?
Question 2) I am using the following code and I want to pass custom data so that when IPN sends me back the transaction message, It will have that custom data in it. I need to pass 2 custom data. How is this possible for the following code? I really couldn't find this one in the docs too.
<template>
<div id="paypal-button-container"></div>
</template>
<script>
export default {
props: ["amount"],
mounted() {
let self = this;
paypal
.Buttons({
createOrder: function(data, actions) {
// Set up the transaction
return actions.order.create({
purchase_units: [
{
amount: {
value: self.amount,
}
}
],
});
},
onApprove: function(data, actions) {
// Capture the funds from the transaction
return actions.order.capture().then(function(details) {
// Show a success message to your buyer
console.log(details);
self.$emit("paypalPaySuccess", {
order_id: details.id,
})
alert("Transaction completed by " + details.payer.name.given_name);
}).catch((err)=>{
})
}
})
.render("#paypal-button-container");
}
};
</script>
Addition of some questions
I am using all the events in dashboard.
I need to add some more questions, because I can't find the information I need.
Question 3) In client-side, I make action.orders.capture().then . which means that I capture funds immediatelly. When webhooks come to my back-end, there're 2 webhooks that come for single payment . (PAYMENT.CAPTURE.PENDING and CHECKOUT.ORDER.APPROVED) . a) why doesn't PAYMENT.CAPTURE.COMPLETED arrive as webhook event? b) what if I want to get DENIED events? If PAYMENT.CAPTURE.COMPLETED doesn't arrive, PAYMENT.CAPTURE.DENIED won't arrive too.
Question 4) As I said, there're 2 webhook events appearing for single payment on my back-end. The first one has id in it. Let's say I store this in my database as id and status(PENDING). Then another event came which is CHECKOUT.ORDER.APPROVED. Now, this one has different id then the previous one. So I can't really go back to database and update the status as this has different id. What should I do? One thing I noted is that the second came event has also another id (the previous came event) somewhere in captured object. is this what i should use it? which one is the final transaction_id?
Question 5) Turns out invoice_id should be unique each time. So I wanted to pass user_id but i guess i also should generate random string and append it to user_id something like this: invoice_id: '7,randomstring'. right?
Question 6) Same event sometimes comes twice. Why is that? Should I return status 200 in order for that same event not to come again? When will it be good to return that status? I guess after I update the database, right?
Q1: IPN is deprecated. You should be using webhooks, such as CHECKOUT.ORDER.APPROVED
Q2: There does not appear to be any specific way to pass custom data.
Option 1:
What I ended up doing was using the invoice_id field in purchase_units. I tested and found that I could pass a reasonably long string of characters and they did not have to be unique. It seems a bit of a hack but it works.
When you implement the CHECKOUT.ORDER.APPROVED webhook, you can then parse the data in purchase_unit invoice_id.
Option 2:
Another idea I considered which doesn't need to hack the invoice_id, is to send data to the server using the details from the capture event in the javascript, store that custom information, along with the order id in the database, and then when the webhook occurs, cross-match the order id to the saved one to retrieve the information.
I prefer option 1, but your needs may vary.
It's pretty indicative though of how poorly designed the whole PayPal API is. There are huge gaps in the implementation, very little documentation, and zero support.
I had to implement Stripe as well. The entire implementation took me 3 days. The same PayPal implementation took me over 3 weeks! The lack of documentation, having to constantly just try things out, and the inconsistency of the sandbox implementation were real time killers.
I am using a paypal ipn script i found here
http://coderzone.org/library/PHP-PayPal-Instant-Payment-Notification-IPN_1099.htm
I am aware that I can send information to paypal and get a response. It states I can get the information back using $_POST . My query is how do I specify the UK currency?
Also wanted to clarify a minor point. Am I correct that this is how i can confirm it was a success.
if ($_POST['payment_status'] == 'completed')
// Received Payment!
// $_POST['custom'] is order id and has been paid for.
}
This might be a little late for you sorry, but just in case - I currently use "currencyCode" = > "AUD" and it is working in the sandbox.
There's a full list of the currency codes available at PayPal
For yours, I'm guessing it would be:
$p->add_field('currencyCode', 'GBP');
As for your question about the IPN itself, it looks like you're on the right track. It will depend on the data you're getting back and whether you're interested in the individual transactions (if using adaptive payments) or if you're reversing them all on error etc. The easiest way to determine what you'll need to do is to simply display or log all the post data so you can see how it's constructed.
You'll also need to set it up so that the script is accessible by PayPal. You'll then pass the full URL of this script to the "notify_url" parameter and send it off to PayPal. Once the payment has completed PayPal will send a bunch of information to your script so that you can process it.
Unfortunately I'm not from a PHP background so I can't give you the exact code you'll need. Also note that there are a lot of security issues that you'll want to look into before going to a production environment. Not sure if you already intend to do this with that validateIPN function, but you need to ensure that you can tell whether it comes from PayPal and not a malicious user. One way would be to pass a value using the custom attribute and have PayPal pass this back to you, however you'd be much better off using the API certificates etc.
If you haven't already, it may be worth checking out a few of the sample applications PayPal has done up, there seem to be quite a few PHP ones.
Let me know if you need anything else,
Use this, it works for me
$p->add_field('currency_code', 'GBP');
You need to use PayPal Adaptive Payments, IPN wouldn't help.
PayPal Adaptive Payments
Using PayPal PHP library then it could look like this:
// Create an instance, you'll make all the necessary requests through this
// object, if you digged through the code, you'll notice an AdaptivePaymentsProxy class
// wich has in it all of the classes corresponding to every object mentioned on the
// documentation of the API
$ap = new AdaptivePayments();
// Our request envelope
$requestEnvelope = new RequestEnvelope();
$requestEnvelope->detailLevel = 0;
$requestEnvelope->errorLanguage = 'en_GB';
// Our base amount, in other words the currency we want to convert to
// other currency type. It's very straighforward, just have a public
// prop. to hold de amount and the current code.
$baseAmountList = new CurrencyList();
$baseAmountList->currency = array( 'amount' => $this->amount, 'code' => 'GBP' );
// Our target currency type. Given that I'm from Mexico I would like to
// see it in mexican pesos. Again, just need to provide the code of the
// currency. On the docs you'll have access to the complete list of codes
$convertToCurrencyListUSD = new CurrencyCodeList();
$convertToCurrencyListUSD->currencyCode = 'USD';
// Now create a instance of the ConvertCurrencyRequest object, which is
// the one necessary to handle this request.
// This object takes as parameters the ones we previously created, which
// are our base currency, our target currency, and the req. envelop
$ccReq = new ConvertCurrencyRequest();
$ccReq->baseAmountList = $baseAmountList;
$ccReq->convertToCurrencyList = $convertToCurrencyListUSD;
$ccReq->requestEnvelope = $requestEnvelope;
// And finally we call the ConvertCurrency method on our AdaptivePayment object,
// and assign whatever result we get to our variable
$resultUSD = $ap->ConvertCurrency($ccReq);
$convertToCurrencyListUSD->currencyCode = 'EUR';
$resultEUR = $ap->ConvertCurrency($ccReq);
// Given that our result should be a ConvertCurrencyResponse object, we can
// look into its properties for further display/processing purposes
$resultingCurrencyListUSD = $resultUSD->estimatedAmountTable->currencyConversionList;
$resultingCurrencyListEUR = $resultEUR->estimatedAmountTable->currencyConversionList;
When requesting the detail payment report via https://paymentreports.facebook.com ( https://developers.facebook.com/docs/payments/developer_reports_api/ ) I always have an empty payment_detail:
SH,COMPANYID,payment_detail
CH,app_id,payment_type,product_type,payment_id,time_completed,recv_currency,recv_amount,fx_batch_id,fx_rate,settle_currency,reference_id,tax_country
SF,0
my request URL with important data left out: https://paymentreports.facebook.com/COMPANYID/report?date=2012-09-30&type=detail&access_token=ACCESSTOKEN
How can I get the payment_detail to contain data?(credits_detail has data)
The problem here was at the time Facebook local currency was not yet used. The reports were for Facebook Credits and thus that part was empty.
I am currently testing an online store using a custom cart within paypal sandbox.
I am able to go trough all transcation steps properly
setExpressCheckout-> pay -> DoExpressCheckout.
During the DoExpressCheckout step I think it would be the good time to update my database with the order. For that I use the GetExpressCheckoutDetails function to retrieve the content of the transaction.
Sadly this function return everything paypal has to offer but miss the content of my cart. All i can get is the detail of one item. If the transaction involve multiple items i would only get the details of the first one.
Here is my code (mostly taken from paypal samples) :
$token =urlencode( $_REQUEST['token']);
$payerId=urlencode( $_REQUEST['PayerID']);
$getExpressCheckoutDetailsRequest = new GetExpressCheckoutDetailsRequestType($token);
$getExpressCheckoutReq = new GetExpressCheckoutDetailsReq();
$getExpressCheckoutReq->GetExpressCheckoutDetailsRequest = $getExpressCheckoutDetailsRequest;
$paypalService = new PayPalAPIInterfaceServiceService();
$getECResponse = $paypalService->GetExpressCheckoutDetails($getExpressCheckoutReq);
$details = $getECResponse->GetExpressCheckoutDetailsResponseDetails;
// $details->PaymentDetails->PaymentDetailsItem this array should hold all items details
// sadly it always have 1 element instead of the full content of my cart :(
$orderTotal = $details->PaymentDetails->OrderTotal;
$PaymentDetails= new PaymentDetailsType();
$PaymentDetails->OrderTotal = $orderTotal;
//
Some stuff with payment details
//
$DoECRequestDetails = new DoExpressCheckoutPaymentRequestDetailsType();
$DoECRequest = new DoExpressCheckoutPaymentRequestType();
$DoECRequest->DoExpressCheckoutPaymentRequestDetails = $DoECRequestDetails;
$DoECReq = new DoExpressCheckoutPaymentReq();
$DoECReq->DoExpressCheckoutPaymentRequest = $DoECRequest;
$DoECResponse = $paypalService->DoExpressCheckoutPayment($DoECReq);
Do i miss a step or call a bad function. Because i tried to print_r every variable i came across and the full content of my cart was nowhere to be found. I find this strange since the 'orderTotal' of the transaction match with my original cart. I could store my original order during the SetExpressCheckout step but since paypal already have those values i find it redundant.
As a last resort I did found the content of my cart using $paypalService->getLastRequest() but seriously this is the raw XML returned by paypal and the api should be parsing it properly :(.
Thanks for reading
I had this exact same issue - while the XML returned by PayPal is fine, their PHP SDK doesn't parse it properly, so you can only ever see the last item in GetExpressCheckout.
I've posted a fix for this problem in an issue on PayPal's GitHub, please check it out:
https://github.com/paypal/SDKs/issues/37
I need to determine when a user's paypal subscription is set to end/renew. I know that the easiest way to do this would be to extrapolate it from the time when the initial subscr_signup gets sent through, based on the subscription interval value, but because I'm working with some 3rd party software, it's not possible (or at least, not ideal).
It seems to me that I ought to be able to send a query to paypal to get this info based on txn_id, but I can't find any documentation that implies that this is the case.
if you send a request with:
TRXTYPE = R -this is to tell it recurring profiles
ACTION = I - this is to tell it to make an inquiry
ORIGPROFILEID = XXX - this is the profile you want to look up
PAYMENTHISTORY = N - this will tell it not to return payment history
from there the array will return something like this:
RESULT[1]=0
RPREF[12]=XXXXX
PROFILEID[12]=XXX
STATUS[6]=ACTIVE
PROFILENAME[1]=0
START[8]=10182006
TERM[1]=0
NEXTPAYMENT[8]=10182009
PAYPERIOD[4]=QTER
TENDER[1]=C
AMT[5]=0.00
ACCT[16]=XXXXXXXXXXXXXXXX
EXPDATE[4]=0101
AGGREGATEAMT[6]=0.00
AGGREGATEOPTIONALAMT[5]=0.00
MAXFAILPAYMENTS[1]=0
NUMFAILPAYMENTS[1]=1
RETRYNUMDAYS[1]=4
NAME[11]=BLAHBLAH
ZIP[5]=12345
What you are looking for is the START, but pretty much all the items in the array are self explanitory.
