I have integrated paypal express-checkout in a website. All seems to work fine. When customer is redirected to paypal for payment, the button Pay Now appears, since I am using:useraction=commit, i.e.:
https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=MYTOKEN&useraction=commit
Customer logs in from Paypal and clicks on the Pay Now button. Paypal gives no error, everything seems to be successful and customer is redirected at the RETURNURL, but no transaction is created in the buyer or in the seller account.
I'm afraid I missed some points from Paypal API documentation.useraction=commit will NOT complete the transaction. After returning from Paypal, we still need to execute DoExpressCheckoutPayment in order to complete the transaction.
Like George said, useraction=commit does not complete the transaction. It only changes the PayPal UI so the customer feels they have confirmed it there, so you don't have to add confirmation UI on your site. You still need to make the request behind the scenes to confirm it.
PayPal's docs say this:
The useraction URL parameter in your redirect to PayPal determines
whether buyers complete their purchases on PayPal or on your website.
If you set useraction to commit, PayPal sets the button text to Pay
Now on the PayPal Review your informaton page. This text lets buyers
know that they complete their purchases if they click the button.
After PayPal redirects buyers to your site, call
GetExpressCheckoutDetails and DoExpressCheckoutPayment to have PayPal
complete the payment successfully. Call DoExpressCheckoutPayment
without waiting for buyer interaction. Use information in the
GetExpressCheckoutDetails response to fill out your order confirmation
page.

I run a small marketplace with multiple sellers where buyers can buy items and pay with PayPal. The problem is, when someone makes a payment, they are then displayed the "Payment Confirmation" on the PayPal website and are given a choice to either return to their PayPal account, or return to the website.
Is there any way to keep the payment flow on my website, except for the payment part? I notice when buying on Etsy for example, the buyer goes to PayPal to make the payment and is then immediately returned to Etsy for the payment confirmation. They never see the PayPal payment confirmation page.
I assume it could be because Etsy and PayPal have a special arrangement that isn't available to other sites? Or am I missing something in the API?
Right now, with the normal PayPal API, this is what buyers see:
NAME, you've just completed your payment.
Your transaction ID for this payment is: XXXXXXXXXXXXXXXXXXXX.
We'll send a confirmation email to your#email.com
Go to PayPal account overview.
Go back to "seller#email.com".
I can't even figure out how to change the "Go back to..." link to my website name in the hidden fields. PayPal just chooses to display the seller's (the person that received the payment) email address.
Is there any way to at least set a website name for them to return to with hidden variables? Keep in mind that I have different sellers, so it's not something I could set inside each seller's PayPal account.
Thank you :)
I assume you are using Express Checkout with Set/Get/Do EC API integration. Please check the below document for experience options available with Express Checkout API.
https://developer.paypal.com/webapps/developer/docs/classic/express-checkout/integration-guide/ECCustomizing/
The 'useraction=commit' in the PayPal payment auth url triigers the 'Buy' button. If you do not send that request paramter then it will show 'continue' button and you can complete rest of the process on your site.
However, if you are using Paypal Payment Standard product then you need to use Express Checkout to accomplish the outcome you are seeking.
Please some one explain what happens if we send useraction=commit in paypal site url.
> And what parameters we need to send to paypal in SetExpress checkout request to make visible purchase value at PayPal site page.
With Express Checkout, you can shorten your checkout flow to let buyers complete their
purchases on PayPal. Then, you can skip your order confirmation page.
Generally, buyers select payment methods as the last step before they complete their
purchases. If you collect no additional information after buyers return from PayPal, you can
skip the confirm-order page on your website. If you collect additional information that does
not affect the payment, PayPal recommends that you collect it after buyers complete their
purchases.
The useraction URL parameter in your redirect to PayPal determines whether buyers
complete their purchases on PayPal or on your website. If you set useraction to commit,
PayPal sets the button text to Pay Now on the PayPal Review your informaton page. This
text lets buyers know that they complete their purchases if they click the button.
As for your other question about what parameters you need to send to PayPal in SetExpressCheckout request to make visible purchase value at PayPal site page, I am not sure I completely understand what you are asking. If you pass over the amount, this will show up on the checkout page. If you are wanting items to show up on these pages, you would need to pass over the line item details. These variables can be found in the Express Checkout Developers Guide, they will be slightly different depending on if you are using SOAP or NVP.

After adding stuff in shopping cart, clicking some Pay Now with PayPal button, and successful PayPal payment (PP or CC), it is logically possible that a user stays on PayPal website, if for example the Auto Return option isn't activated (or it is but it doesn't work because the user is a guest user without PP account)
The user can return to the site by clicking a link, but doesn't have to. My question is: if he doesn't, how will the site owner be aware that the user paid so that he can now send the items by post? That the site owner gets informed of being paid seems elemental to me, so I find incomprehensible that such elemental thing be left to some obscure Auto-Return option.
Please can somebody explain this to me?
This is a common challenge with any redirected payment gateway, and it's the reason most (if not all) of them implement some sort of asynchronous notification that a payment has been completed. In PayPal, this is the Instant Payment Notification (IPN). You must setup on your site either a generic IPN listener that you link to from your PayPal account profile settings or you can create a more targeted IPN listener specifically for your transactions and use the NOTIFYURL (or related) parameter in the form or API request you use to redirect to PayPal to send IPNs to that listener.
In my integrations, I never perform any order update or transaction logging when the customer returns from the site, preferring instead to wait for the IPN that I can validate and ensure came from PayPal as opposed to a spoofed return from someone trying to hack my checkout process.
For more information, see the IPN documentation: https://www.x.com/developers/paypal/documentation-tools/ipn/integration-guide/IPNIntro
Paypal provide IPN for this purpose through which we paypal send request asynchronous to your site and you can perform whichever action you want
I think the point may have been missed here. Or a problem does exist. If the purchaser uses CC, even if you have IPN set up and it works, but if the purchaser uses CC and does not click a button on the last page, which is not presented when using PP account, it is possible for the funds to go through, but no IPN, and so your website is unaware of the purchase. This last page, is an extra page that CC user gets after the page with the Pay button on it.
In this state, you can even go into IPN history, and the IPN is there, says it is sent, but it hasn't been. It does not get sent until after the purchaser clicks the button on the extra page and then they are taken to the auto return page.
We are using Paypal recurring billing service (using Express Checkout) at our website for monthly subscription.
Since we have an Australian account so we are not able use the DPRP (Direct Payment Recurring Payment) service offered by Paypal because it seems, DPRP service is limited
to only few countries (US, UK and Canada).
In Express checkout payment details are received at Paypal Website. So we do not have any information, whether the payment failed, user pressed the Back button in browser or He/She intentionally clicked the cancel payment.
After speaking to Paypal support team we get know that there could be multiple possible reason for Payment failure, and seller has to contact Paypal by themself. So we can
not provide any troubleshooting for that at our website.
So we want to know, Is there any possible solution to avoid this or atleast can we diffrentiate between the user for whom payment failed and who intentionally moved to
our website back without doing payment because this way we are not only unable to followup with them but also loosing a part of the customer base, interested in our service.
Any help in this is Appreciated.
Thanks
You should implement the Pay Pal IPN (Instant Payment Notification).
You configure the IPN url address on your PayPal merchant account settings. This page is simple HTML page with server-side programming that is listening for requests coming from PayPal.
There's no need to do something extra in the checkout process for making IPN work. Once you set this up, it will automatically work.
Every time something happens with a transaction in your merchant account, e.g. transaction completed/failed/canceled, PayPal will send an HTTP Post to your IPN listener URL.
Here you can get all the relevant information about the transaction, like the payer ID, the payment status. With this information you can decide what to do with your customer's order.
I developed a small payment process that uses the Express Checkout API. I'm testing the code with my friend's account with $1. My payment process is redirecting to the live paypal site, he enters his information and pays, he is redirected to my confirmation thank you page, but I never receive funds. I've checked my API credentials in the code, and they are OK. I'm receiving a token and paypal payerid info on my confirmation screen. What could be the problem?
Thank you in advance.
See my answer in Why is DoExpressCheckoutPayment required for Paypal?
In order to use Express Checkout, you must call at least the following API calls:
1. SetExpressCheckout -- to set up the transaction.
2. DoExpressCheckoutPayment -- to finalize the transaction.
If you don't call DoExpressCheckoutPayment on the 'Thank you' page, the transaction is not completed. This is by design to allow for greater flexibility
Express Checkout is intended as a drop-in solution in your own checkout process. After Express Checkout redirects you back to your site, you're supposed to show an order confirmation where the buyer can review his/her final order details before initiating a button / link which initiates the final DoExpressCheckoutPayment API call. This is why DoExpressCheckoutPayment is required.
