I have several ambiguities in using paypal methods and cases, when IPN messages are sent. Im developing app, in which im using paypal(sandbox) for making deposits and cashouts. Each of these both transactions I want to log in my app and here some obscurity raises becouse I need to capture as many cases that may occur. So I'll take it gradually and I'll be thankful also for each partial response.
Firstly, I have some general questions:
In my app, im using BuyNow button, AdaptivePayment methods PAY and PaymentDetails and Merchant method GetTransactionDetails. Are these methods part of Bussines account and for free (there are no monthly fees) right? I cant afford to pay some monthly fees from begining.
May arise any problems, when i'll deploy it to non-sanbox environment?
cashout
For cashout Im using Adaptive payment PAY method.
When My app client make a cashout to his/her paypal account, I can catch through IPN message, that payment is completed and using AdaptivePayment PaymentDetails method and Merchant GetTransactionDetails method I can find out, that there is pending status with paymentreview reason. So on receiver side, where I dont have access, is payment review possibility. Thus receiver can DENY payment and here is a question, how to get information about this user action, becouse an IPN message doesn't come.
Another case that im facing is when client of my app make cashout to
his/her bussines paypal account with different currency from sender
(my bussines paypal account). There is pending status too, but with
reason "multicurrency" in IPN message. Here is similar problem to
previous point 1)... again, I cant get IPN message, which
determine, if user accepted or not the transacion.
deposit
For deposit Im using PayPal standard Buy now button.
PAYER SIDE(my app client): I dont understand, why there is payment
review (accept/deny) in payer account profile, when status of
payment is completed? Is it common behavior only in sandbox
environment? Or is it possible accept/deny payment on payer side in
non-sandbox?
RECEIVER SIDE(my bussines paypal account): There is payment review
too, on receiver side, and if im right, these links (accept/deny)
are similar to links on payer side, arent? There is refund
posibility too, exists some API method to refund programatically?
Correct, each of the products you mentioned do not have a monthly fee.
If a user accepts or denies a pending payment that would trigger another IPN with the completed status. Are you saying you've tested this specifically and you're seeing otherwise?
Receivers would only have to accept/deny in cases where there is currency conversion or maybe they have fraud filters set to flag specific transactions, etc. In most cases there should be no review necessary.

I have a page on my site which sends out payments to more than 1 person. I've been testing this using the paypal sandbox account with a few test accounts.
I am also using ipn to get feedback from paypal when payments are complete, pending etc.
My question is, paypal sends me back info via ipn for just 1 of the payments. Why is that? When I check the payment amount in the ipn, it only shows me the payment for 1 of the people who got paid. For example:
If I pay person 1 and 2, where each person gets paid $10 each, so a total of $20. The ipn page only shows me the details for person 1 and says that the payment amount was $10, when the total payment amount is $20.
This is causing me a problem because I need to know that both payments were successful via ipn. At the moment I can only check the payment for 1 person at a time, even though I am paying 2 people at the same time.
How do I get payment for both people?
#Pete answer is a violation of the Paypal User Agreement (unless you have a separate legal entity for both accounts)
9. Restricted Activities
9.1 Restricted Activities. In connection with your use of our website, your Account, or the Services, or in the course of your interactions with PayPal, a User or a third party, you will not:
a. Breach this Agreement (including, without limitation, opening multiple PayPal accounts or breaching the Card Processing Agreement, the Acceptable Use Policy or any other agreement that you have entered into with PayPal (including a Policy));
What you are looking for is PayPal Adaptive Payments. A note about this though: one account - probably you as the application owner - must have a PayPal business account. The others that receive a payment only need a personal account.
PayPal provides an SDK with samples for the Adaptive Payments on Github. Select Adaptive Payments from the menu on the left. There are samples for multiple languages that should be able to get you started.
My hunch is that IPN is tied to the individual account, not the payment, and you have the IPN set up from just one of the accounts. I think what you need to do is configure the IPN on both accounts and then process the response from PayPal two times... once from the IPN notification of the first account, and once from the IPN notification of the second account.
I am running a e-commerce website and I want to integrate PayPal. I need to know immediately whether a user paid successfully or not after they paid via their credit cards. Is there a chance i can do that with PayPal?
I've heard PayPal has a service called IPN, which can post to my server and tell me the transaction's status. But lots of people are complaining that there are huge delays with IPN's PHP API.
Just finished an IPN integration a few hours ago :).
IPN stands for INSTANT payment notifications. In most times it just works(hi Apply fans!).
You add a form with variables such as currency and return URL and with a special page that you expect Paypal to send transaction information when the payment is made. Receiving a notification does not mean funds are sent to your account but the transaction has completed. (possible reasons to not get funds to your account include problems with card provider, incomplete accounts, etc)
You will face some questions regarding specific problems. But I would suggest checking paypal site and it's API docs. They are pretty straight forward and with a little understanding in your programming language and how HTTP works, you can implement it.
I have seen some posts about PayPal IPN system is slow. I have not seen it myself but in most cases, I'm sure you will get paypal API calls just before the user come back to your site.
I've had great success with nSoftware's PayPal plugins.
I'm doing a project involving Paypal, more specifically with the NVP API in PHP. But I just can't seem to figure what to use the IPN feature for.
I mean, when the user has been redirected to Paypal to confirm the purchase, he is redirected back to my website's "Paypal-succes-page", when the transaction is complete. And just to be sure that he actually payed i could use the "PaymentDetails" operation.
Now where does IPN fit in this process? and what is the benefit of it?
Thanks
The integrate with PayPal's services you will notice there are three main channels (and IMO it's important to know this so you can decide the benefits for your application):
IPN: Instant Payment Notification
PDT: Payment Data Transfer
PayPal's API
To use PayPal's IPN you need to add a 'listener' script (example) and add the address to your PayPal account. Whenever an event occurs PayPal will send a message directly to your server via your listener and you then update your accounts appropriately. This is especially useful for running subscription services as events will occur in the background without user intervention and you can capture successful/failed recurring payments etc.
PayPal's PDT is a system for accepting data when a user is redirected back to your site from PayPal. For example, a user clicks 'Buy', they are directed to PayPal, enter information etc. Then, once the payment has been taken, they are redirected back to your site. PayPal can pass details about the transaction including whether it was successful or not so you can display the appropriate success/failed page from your site.
PayPal's API allows you to integrate more deeply with PayPal's services, and you would use this if you were managing payments directly from your site.
These services aren't mutually exclusive, so you can use any combination with your application.
I hope this helps
The IPN feature is a very useful feature which you should use to update your database in my opinion. Sure the user is redirected to your success-page after the purchase where you can validate the payment details.
But what if he closes (by accident or not) the browser before reaching your success page? You will never know the result of the transaction and you will never update your database or process his order accordingly.
When using the IPN you can be sure that the transaction result will always reach you because PayPal will keep on making an offline request to your IPN page until it has reached your servers.
Instant Payment Notification
The typical usage of the IPN is to validate the purchase and to let your script or management system know that the transaction is complete so your system can update any records you may have for your service.
But the most important part is that the transaction is validated.
IPN send all data about transaction to your server - price, items, contacts ... so you can check, if someone don't pay you only 1$ instead of 100$ and confirm your order. It prevets thiefs, cheaters, ... USE IT! ;)
I'm just starting out with Paypal, so this is a newbie question.
I've been going through the instructions for setting up Paypal subscription service, but I think I'm looking at the wrong thing.
What I want to acheive is to get back some kind of response from Paypal so that I can update the database on my web site to mark a registered user as having paid. Basically I have a flag in the database that says if the user is subscribed or not. I want to ensure that the user is marked as paid so long as their Paypal subscription is maintained.
While the instructions linked above do say how to set up a button to receive a payment, there's nothing there about getting any data back from Paypal.
I know there are terms like IPN and sandbox that are related to what I'm trying to do, but I can't find clear instructions for how to get started on this process. I'm just circling around and not getting anywhere.
Where do I start on setting this up? Where is there a clear beginner's tutorial?
Also, I'm using PHP/Javascript/MySQL on my website.
PayPal's IPN service is what you want to use. I've used it myself to do just what you're looking to do.
Instant Payment Notification (IPN) is PayPal's message service that
sends a notification when a transaction is affected. Once IPN is
integrated, sellers can automate their back office so they don’t have
to wait for payments to come in to trigger order fulfillment. IPN can
send notifications for these transactions:
Instant payments, including Express Checkout and direct credit card payments
eCheck payments and pending, completed, or denied status payments
Pending payments
Recurring payments and subscriptions
Authorizations
Disputes, chargebacks, reversals, and refunds
You can also view notifications on PayPal’s IPN History page and
resend them if you need to. As PayPal’s interface for handling
purchase confirmation and server-to-server communications, IPN can
also be used to manage and customize a variety of APIs and
communications, including:
Customize your website's response to customer purchases in seconds
Track customers via IPN "pass-through" variables
Notify sellers who deal mostly in software downloads and other digital, online goods
Track affiliate sales and commissions
Store transaction information in your own database

Code Samples
I'm not sure if its the same thing, but I just setup my friends website with Express Checkout, and I wanted to add all paid orders to an orders table in my database.
After I call SetExpressCheckout, and the user is returned to my site after going through the purchase flow on Paypal's side,
I used the information from GetExpressCheckoutDetails.
Then, if DoExpressCheckoutPayment
is successful (also called from the "callback" page) I then do the appropriate work in my database as far as logging the order details. For you in this case, it could be updating a record for the user in the database.
Hope that helps a little.
I'm looking to implement a very simple Paypal integration whereby I can enter a valid Paypal Email address (recipient) and a dollar amount, and click "Pay." Ideally, it would send the money from my paypal account automatically via my API key.
I currently have Mass Pay set up with PHP, and it's working fine, except that it charges me 2% on every payment, and doesn't pass back the Transaction ID. It also kinda seems unnecessary since I don't need to pay multiple people at once.
Since I only need to do one transaction at a time, I'm wondering if anyone knows of a simpler Paypal API for single outgoing transactions from my account.
I've been reading the documentation all day and I've yet to find what I'm looking for.
Any advice is greatly appreciated!
PayPal has sample codes for integrating various PayPal features on it's website. This includes PHP take a look at the list of features and I'm sure what you are looking for is there.
Also from the paypal site:
PayPal receives the MassPay request and returns a response indicating
success or failure. If PayPal returns a successful response, then
PayPal processes the payments and, if you have Instant Payment
Notifications (IPN) enabled, PayPal sends a notification to the Notify
URL specified in your account profile. If you do not have IPN enabled,
you can view the details of the MassPay transaction in your PayPal
account.
This implies that in the case of mass pay you need to provide a URL where paypal sends payment notifications. Your program can probably check this url to figure out whether a payment has been made or not, I would suspect this would be the case for all payment integration. That being said I would print_r the the response from paypal, I'm sure something like a transaction id will probably be in there. In the case of DoAuthorization it does return the transaction id
In the case of mass pay it does return the transaction id if IPN is enabled
