I want to display description of items like this:
I wrote my solution according to this article and attached to this asp.net solution.
However, on the PayPal login page (such as in the first picture), I see only the purchase and amount (not as in the first picture).
I use these URLs to create a transaction:
Sandbox - https://pilot-payflowpro.paypal.com/
Live - https://payflowpro.paypal.com
To setup transaction I send these parameters:
"PARTNER"
"VENDOR"
"USER"
"PWD"
"TRXTYPE"
"AMT"
"CURRENCY"
"CREATESECURETOKEN"
"SECURETOKENID"
"RETURNURL"
"CANCELURL"
"ERRORURL"
"VERBOSITY"
"BILLTOFIRSTNAME"
"BILLTOLASTNAME"
"BILLTOSTREET"
"BILLTOCITY"
"BILLTOSTATE"
"BILLTOZIP"
"BILLTOCOUNTRY"
"SHIPTOFIRSTNAME"
"SHIPTOLASTNAME"
"SHIPTOSTREET"
"SHIPTOCITY"
"SHIPTOSTATE"
"SHIPTOZIP"
"SHIPTOCOUNTRY"
I have tried to define line-items description using those parameters:
"L_QTYn"
"L_NAMEn"
"L_DESCn"
"L_COSTn"
"L_TAXAMTn"
where n - line number from 0 or 1 (I can't remember now)
I have also tried those parameters:
"L_PAYMENTREQUEST_m_NAMEn"
"L_PAYMENTREQUEST_m_NUMBERn"
... and so on
I didn't get any changes in all cases.
So, what have I missed? Is it possible to display items for PayflowPro Express Checkout?
Thanks for referencing my article :)
To pass EC line items through Payflow, there are two solutions:
A) Contact www.paypal.com/mts and ask them to toggle the Features BitMap that enables EC line items
B) Add this to your request: "_TRAILER_PASSTHROUGH__=Y"
Note that (B) can change the format of the responses you receive from Payflow to have value length tags, i.e. NAME[5]=VALUE instead of NAME=VALUE, so parse accordingly...
(In particular, this will happen when the VALUE returned from PayPal contains special characters such as "&" within it, so you can't simply split the string on "&")

I am developing an api.ai bot that will search for the Vendor name in the database.
a ) if vendor exist -> provide username -> provide password
b) if vendor doesn't exist -> (add vendor -> yes ) or (add vendor -> No)
I have a webhook which is checking the vendor exist in database or not .
Bot Scenario: (Example )
Case1:
User: Do Alpha exist as a vendor?
Bot: yes, Alpha exist in Database. Please Provide User Name.
User: abc#gmail.com
Bot: Please Provide Password?
User: abcdef
Bot : Welcome
Case 2:
User: Do Beta exist as a vendor ?
Bot: No Beta is not a vendor. Do you want to Register?
Case 1:
User: Yes
Bot: Please fill this Form.
Case 2:
User: No
Bot: Is there any other way I can help
One thing I have figured out, I have to use output context to trigger the intent. But how can I do it in this complex case? and how can I call multiple to follow up intent using Output Context?
I might be using a bad approach, Is there any other way to solve this ?
I do have a follow-up question.
when we pass the fulfillment response back to dialogue flow. The response print on bot console will be the default text response, how can I get "fulfillmentText" to be the Response.
Thank you Guys. This is the followup Intent scenario.
This is not complex, you are doing it wrong by having two intents for collecting username/password.
Try the following way
When you detect that your vendor is present - set the context in webhook, as say, "vendor-present"
When the vendor is not present - set the context in webhook, as say, "vendor-new"
Use lifespan (the number at the left side of the context) to set the lifetime or validity of the context.
Create a separate intent for existing vendor - say "Vendor Data Collection" for collecting username and password. Set input context as "vendor-present" in the Dialogflow. Here you will collect these as parameters in the same intent (see image below). Mark these parameters as 'required' so that they must be collected by your bot. Use the Prompt section to put your response question for collecting information like "Please provide username".
If the vendor is not present, use existing intents and set input context as "vendor-new" in the Dialogflow.
Now, few things to note - the username parameter can be collected using the system entity #sys.given-name. But it is not very accurate with the Non-American/English names. I am not sure if this is improved or not. Secondly, there is no system entity to collect passwords, so you need to set the entity as #sys.any and in the webhook, you need to use regex to extract passwords on your own. BTW - you are not supposed to share passwords!
Hope this helped you!
I am having a issue with a paypal cart since the update around march (bit late but the site is not used yet and we just discovered it now).
I already checked this question but it did not solve the issue for a shopping cart (Paypal : hosted button payments fail with code=AMOUNT_ERROR)
We send a object that contains the request data through a plugin called neo.js, this works fine as far as we know.
This is our data we send to paypal as a js object.
{
amount_1: 10.01,
business: "noreply#domain.com",
cancel_return: "https://dev.domain.com",
charset: "utf-8",
cmd: "_cart",
currency_code: "US",
custom: "username",
item_name_1: "$10 item",
item_number_1: "1",
no_shipping: 1,
notify_url: "https://dev.domain.com/callback/paypal.php",
quantity_1: 1,
return: "https://dev.domain.com",
upload: 1
}
It has to do something with the amount, but using a , instead of . but that only gives a normal error message on screen that the format is incorrect.
We have tried multiple things including the dollar sign and making it a string but nothing seem to be working.
I reproduced the error and it is due to the wrong currency code passed.
You are passing "US" but the currency code (that is a parameter that refers to the AMOUNT as in the error returned) must be of 3 characters as you can see on PayPal guide: https://developer.paypal.com/webapps/developer/docs/classic/api/currency_codes/
Change it to "USD" instead and you will have a working checkout.
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;
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
I am trying IPN callback, using servlet. The code I am using is provided by paypal for verifying the ipn data. But every time i getting a INVALID response.
Here is the code:
Enumeration en = req.getParameterNames();
String str = "cmd=_notify-validate";
while (en.hasMoreElements()) {
String paramName = (String) en.nextElement();
String paramValue = req.getParameter(paramName);
//str = str + "&" + paramName + "=" + URLEncoder.encode(paramValue,"UTF-8"); // for UTF-8 i set the encode format in my account as UTF-8
//str = str + "&" + paramName + "=" + URLEncoder.encode(paramValue,"ISO-8859-1");// for ISO-8859-1 i set the encode format in my account as ISO-8859-1
str = str + "&" + paramName + "=" + URLEncoder.encode(paramValue); //default as provided by paypal
}
URL u = new URL("http://www.sandbox.paypal.com/cgi-bin/webscr");
URLConnection uc = u.openConnection();
uc.setDoOutput(true);
uc.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
PrintWriter pw = new PrintWriter(uc.getOutputStream());
pw.println(str);
pw.close();
BufferedReader in = new BufferedReader(new InputStreamReader(uc.getInputStream()));
String res = in.readLine();
in.close();
if (res.equals("VERIFIED") || !res.equals("VERIFIED")) {
//Update database...
} else if (res.equals("INVALID")) {
//INVALID
}
I have checked all three possibilities provided by paypal in case paypal return INVALID as follow:
1) Missing Parameters - As I am send all the parameters no issue of missing parameters
2) Invalid URL. - I am using sandbox so URL is : http://www.sandbox.paypal.com/cgi-bin/webscr
3) Character encoding. - Tried with character encoding same as paypal account setting parameter encoding.
the request I am sending back to paypal using following parameters:
cmd=_notify-validate&last_name=User&test_ipn=1&address_name=Test+User&txn_type=web_accept&receiver_email=sellr1_1252495907_biz%40gmail.com&residence_country=US&address_city=San+Jose&payment_gross=&payment_date=01%3A55%3A04+Sep+26%2C+2009+PDT&address_zip=95131&payment_status=Completed&address_street=1+Main+St&first_name=Test&payer_email=buyer1_1252495751_per%40gmail.com&protection_eligibility=Eligible&payer_id=BXBKS22JQCUWL&verify_sign=AOMkeg7ofCL7FJfioyWA19uCxD4XAgZirsjiGh8cUy1fd2YAqBwOkkst&payment_type=instant&business=sellr1_1252495907_biz%40gmail.com&address_country_code=US&mc_fee=0.64&address_status=confirmed&transaction_subject=True+Up&quantity=1¬ify_version=2.8&mc_currency=EUR&custom=&address_state=CA&payment_fee=&handling_amount=0.00&payer_status=verified&shipping=0.00&item_name=True+Up&tax=0.00&username=hannonj&charset=windows-1252&item_number=567&mc_gross=10.00&txn_id=7F456350BS7942738&receiver_id=MASSU6BSR9SC2&address_country=United+States
Please , can any one direct me to proper direction? I am not getting what is wrong the code or the URL or anything else. I tried all the possibilities. Please help me.
An “INVALID” message is due to the following reasons:
Check that your are posting your response to the correct URL, which is https://www.sandbox.paypal.com/cgi-bin/webscr or https://www.paypal.com/cgi-bin/webscr, depending on whether you are testing in the Sandbox or you are live, respectively.
Verify that your response to the test IPN message contains exactly the same variables and values as the test message and that they are in the same order as in the test message. Finally, verify that the original variables are preceded by a cmd=_notify-validate variable.
Ensure that you are encoding your response string and are using the same character encoding as used by the test IPN message. (for example, I can see that he is using letters with umlaut and other symbols like “/”, etc).
With regard to the last point, the merchant can try to change the encoding language in use in his PayPal account, following the steps below:
Login on you PayPal account
Click on Profile
Click on “My Selling Preferences” tab
Click on “PayPal Button Language Encoding” (at the end of the page)
Click on "Other Options"
Select from the drop down menu: UTF-8
Choose the same charset also for the second option, which is related to IPN
Click “Save”
If the issue persists, we recommend to review the script in use, PayPal has some IPN code samples available at: https://github.com/paypal/ipn-code-samples
For additional information I include the link: https://developer.paypal.com/webapps/developer/docs/classic/ipn/integration-guide/IPNTesting/#id091GFE00WY4
I'm pretty sure the URL to send to is just "www.sandbox.paypal.com", see chapter 4 of Sandbox User Guide, and well, this is what I put for my own code (incidentally, for live, it is also just "www.paypal.com", for their sample code)
Thank you guys for your reply.
ohhh I solved it at last.
Actually in notify URL I also added a username parameter. Paypal want the parameter values for IPN same as it return to the servlet.(You can get it as req.getParameterNames()). As I have username parameter extra, which is not known to paypal. Paypal was returning INVALID.
Remember paypal's sandbox has completely different credentials. You must have development account and be logged into development panel to use sandbox.
If you're testing Paypal IPN over SSL, you will have to use ssl://www.sandbox.paypal.com on the port 443
I ran into multiple problems layered on top of each other before I could get Paypal IPN working - it kept returning INVALID but was not specific about which part I was getting wrong, unfortunately.
Things I got wrong:
Sandbox - if you use the Sandbox you need to use the entire Sandbox environment. It requires creating a new, separate account on the Paypal Sandbox website. The Sandbox API credentials it sets up under your regular account are not enough. You then use that separate Paypal account to file fake transactions on the Paypal Sandbox website, and watch them come across IPN on the Sandbox endpoint. The need for this second account is not obvious or clear at all in setting up API access. Also, switching between Sandbox and Live requires more than switching the URL, you need to switch the credentials. So a simple compile flag alternating a string isn't going to cut it.
Live - if you use the Live environment a number of things will get in your way. For us, it took a long time for Paypal to open up "Business" access to us. It wouldn't provide us anything over the API until that was enabled. When we initially applied we were flatly denied with no explanation or timeline to resolve it. A month later ish of taking payments (with no API to keep us up to date with those payments) it seemed to just magically start working.
Code example - the code example provided by Paypal is outdated, and has some clear issues. Here's an example that uses modern TPL/async:
// Send the verification back to Paypal in the format Paypal requested
var verif = (HttpWebRequest)WebRequest.Create(ipnVerifyUrl);
verif.Method = "POST";
verif.ContentType = "application/x-www-form-urlencoded";
var param = req.BinaryRead(req.TotalBytes);
var sRequest = Encoding.ASCII.GetString(param);
sRequest = "cmd=_notify-validate&" + sRequest;
verif.ContentLength = sRequest.Length;
using (var streamOut = new StreamWriter(verif.GetRequestStream(), Encoding.ASCII))
{
await streamOut.WriteAsync(sRequest);
}
// Send it
using (var re = await verif.GetResponseAsync())
{
var s = await HttpWebRequestAsync.GetFullResponseStringAsync((HttpWebResponse)re);
// Log the response (s)
}
Besides this code actually working (This is exactly what we have in Production, with some of our logging library calls stripped out), this code won't freeze a thread while waiting on network.
The awaits allow the thread to step away while the network does its thing, both in writing the verification request to Paypal, and in receiving the response back, both of which could be a long time.
