Im planning to allow people to create premium accounts on a site. There is a simple registration form, at the end of which I want to direct people to paypal where they will make a payment, and then be sent back to my site with their newly created account now activated (if transaction went thru).
I dont want a fully hosted solution ("Website Payments Pro"), but something where you leave the site, and then come back to it after payment.

API Reference
Using the PayPal API, you'll be able to send users to PayPal to handle payments. Once the transaction has been completed it will then send a response to a script on your site, which you can then act on accordingly. For example, update a particular user's status as 'Paid' or 'Unpaid' in your members database table.
You want to look at PayPal IPN. With that, you can send these pages URLs as hidden fields and PayPal will then return the user to the page you submitted for success, failed, IPN handler etc.
Yes that's possible, look into the "Buy now"-method on PayPal, they have an off-site payment possibility and they have on-site payment. It's up to you how much you want to spend on both time and percentage on each sale.

I have a system that simply registers a user. I need to intergrate this with PayPal so that only IF a user has paid can they have access their account. Paying involves confirming to a monthly payment, with the first month free. I need to use some PayPal API that will inform the user of the monthly fee, let's them subscribe, and then if it was a successful returns True to my PHP system so It can then activate the account.
So what do I need to do to get this process running? What will I need to do?
https://developer.paypal.com/ is a great place to start.
They offer guides and code libraries and examples there.
And as far your rest of the requirement, you can handle that in callback from paypal. according to payment status and update your record and notify the user.
You need a Form from Where you post information to Paypal (which you can find in paypal SDK
Paypal Will process the payment once form correctly posted.
Paypal will send you response on your callback.php file of which file link you post in Form.
Handle all your conditions in that callback file.
I have a website that allows my users to donate to charities via PayPal. I want to track the donations that a user makes, but I don't have direct access to the charities' PayPal accounts.
This is kind of a follow-up to this question, which provides a good explanation of IPN tracking, but I think it relates to tracking payments made to an account which I own.
Is it possible to send confirmation of a donation to a third party back to my website so that I can track it?
P.S. I really hope this isn't the wrong way to post a follow-up question, and that it doesn't count as a duplicate...
If you use notify_url / NotifyURL in your Payments Standard code or API requests you can override the PayPal account profile and have it send the IPN to whatever URL you specify in that parameter.
I want package sales, when user click on purchase want to send user on paypal site, after success payment back to my site, I will update payment status if payed other wise will not update the payment status. 2nd question how will i know user payed?
PayPal IPN allows the PayPal servers to interact with yours, telling them statuses about if they've paid, missed payment or it failed etc.
https://www.paypal.com/ipn
For example, if you're using the Website Payments Standard (https://www.paypal-business.co.uk/accept-online-payments-with-paypal/index.htm) you send them to the PayPal site by sending hidden information in a form, they do their thing on PayPal and then get sent back. PayPal will then notify the server using the IPN details that were either sent or are in the account, letting the server know if it was successful or if anything else happened. Then your application that picks up the IPN, does its security checks, and then does the appropriate action (e.g. allows the item to be sent or them to login etc).
However - if you're doing subscriptions, I highly recommend not using PayPal. They suck for subscriptions.

and follow the step by step guide.
If not work then ask question here.
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 have site with a members area that I've set up and want to make it so when people register, they need to subscribe to paypal, and only then the user is created in the database.
I don't know much how paypal works. Does anyone have any pointers? How or where do I start?
Basically I need to somehow redirect the visitor to paypal after he presses the "Register" button, make the payment, and then make Paypal return to my site and tell it that the payment was processed, so the user can be created...
Paypal IPN is the Paypal deployment for this kind of requirement.
IPN (Instant Payment Notification) allows you to delegate an endpoint URL that the payment gateway will send postdata to when a payment is completed successfully.
Most of the time this requires utilizing some kind of database to save the registration state while the user is forwarded over to Paypal for the payment process, making use of their SSL encryption and payment logic. When the process is completed, your application is notified with post data containing a unique identitfier generated by your app and passed with the original redirect in order to identify the user's session that has completed payment.
You will want to generate a unique id either using PHP uniqueid() function or by hashing a timestamp. This will be passed along to paypal in your redirect, and paypal will send it along with success/fail flags when the payment is processed. When the user fills out their form and is redirected to Paypal, save a boolean value for IsPaid in your database associated with their ID (i'd recommend using both a primary key as well as this unique transaction id mentioned earlier.) Your IPN script can then listen for the post data, parse it out and change the false IsPaid boolean for that id to true.
There are numerous good tutorials available. I've only used this in MVC deployments, so if you're doing procedural, googling around will help a great deal. Paypal's documentation has the most up to date parameter guides but there are other great, if a bit old, tutorials available independent of them.

Look at the Paypal IPN API, this is used in most paid membership scripts:
