I am currently working on developing a plugin for subscription in WordPress.
I have integrated PayPal with the plugin but the problem is that how can I get the payment status from PayPal?
I have set return parameter to my subscription page but it does not receive payment status and other parameters from PayPal.
You'll need to use IPN for that. It will POST data to your application about every transaction that hits the account so you can process them accordingly, automatically and in real-time.
You can use PayPal IPN for WordPress to get up and running quickly. It comes with lots of different hooks to trigger your own stuff based on different transaction types or payment status (note: these links are to my own website).

I'm working on a website where a user can pay for products to another user, the user that is getting paid has his API Signature set and the payment is accomplished using ExpressCheckout (NVP) (the payer just gets redirected to a PayPal page where he logs in if necessary and just clicks a button to pay).
The problem is I tried using webhooks to track refunds for these payments, so I can later insert the refund data into my database via callback URL (php function), but the URL I've set doesn't get called at all(I've previously simulated an event on the same URL and everything was fine).
I am trying to get this to work by setting my API Signature and a friend of mine paying me some cents(via DoExpressCheckoutPayment) after which I refund them to him (no calls, only using the PayPal website).
Also nothing appears on the Sandbox Webhooks Events page or the Live one. I've tried registering other events like "Payment capture completed" or "Payment sale completed" to my webhook but with the same result.
Do I have to change some settings in my account? I've created a REST API app in order to use webhooks, but I've seen there's an option for NVP/SOAP API apps. I have considered IPN if webhooks don't work.
"Webhooks" are used with the REST API. Express Checkout uses IPN.
You'll need to setup a separate listener for IPN similar to what you've done with webhooks on the REST API.
I haven't tested in live, but currently I have a webhook subscribed to the following events
Billing subscription cancelled
Billing subscription created
Billing subscription re-activated
Billing subscription suspended
Billing subscription updated
I'm receiving Webhook events for CREATED but nothing is being sent when a user cancels the subscription from their PayPal dashboard.
Is this expected behavior? is there another event I should be subscribe to to capture that user action?
Is there a debug id that you can share so we can trouble shoot?
Thanks,
Usha
From Paypal support (I still don't understand why the BILLING.SUBSCRIPTION.CANCELLED doesn't fire when a user cancels from their dashboard, similar issue here: BILLING.SUBSCRIPTION.CANCELLED does not fire upon user action?)
"But surely users subscribing via the button is the most common method of subscribing (how else would they subscribe?). The IPN route seems like a completely non-developer-friendly one (seeing as there isn't even simulator events for it)"
If you integrate a solution which is not based on our REST API's and want to receive HTTP notifications, you need to use instant payment notification (IPN). The IPN simulator may not provide a method of simulating the events, but you can create subscriptions in our sandbox environment and setup a sandbox business account with IPN and test cancelling the subscriptions, which will generate an IPN for the cancellation. We have a sandbox testing guide available here if you're not familiar with that environment and want to get started.
"So why would webhooks ONLY fire for API-based subscriptions (and why would a business website subscribe users using the API rather than the simple button)? What is the logic behind this?"
It depends on the integration and needs of the individual business. Some businesses only use our REST-based API solutions for their complete integration, from checkout payments to subscriptions and logically, this makes sense to them to only have to use one set of API's for their complete integration. Other business only want / need a more simple solution such as using buttons and as these are legacy solutions which are not REST-based, they use our legacy HTTP notification service which is instant payment notification (IPN).
I am building website which requires customer to update paypal account.
Is there anyway to check the reality of customer's account?
When my customer fill out their paypal account in my site, I want them to be directed to paypal login page to login and paypal will return the result.
Does paypal api support this situation?
Pretty much any implementation of PayPal you choose would follow the flow you mentioned.
Payments Standard would allow you to create basic buttons or create an HTML form and POST directly to PayPal to process. It would send the user to PayPal for login and approval to complete the payment. The transaction details would include the payer status (verified or unverified) as well as the address status (confirmed or unconfirmed) and lots of other details about the order.
Express Checkout is basically the API version of Standard, but it's much more advanced and open to integrate in the way that works best for your site or application. In this case, some of buyer/transaction data is available during the process within your app through API requests and responses, and then you can also get to it via transaction details after the fact just like payments standard provides.
Another option would be to use Adaptive Payments, but if you're doing a general payment of any kind you probably don't need that. That's what you would use if/when you start wanting to split payments among multiple receivers within the same transaction, setup preapproval profiles, etc.
If you happen to be working with PHP my class library for PayPal will make the API calls very simple for you.
You could do what PayPal itself does when you register. Send them a few cents and have them tell you how many when they get it. The payment itself will fail if the account doesn't exist, and telling you how many cents proves that they own the account.
Using the PayPal permissions API can you receive notifications from payments made after a customer clicks on a payment button, proceeds to PayPal, and then pays?
I notice they have IPN, but will this work with the permissions API?
Thanks!
You can include NotifyURL in your API requests to set a URL for IPN to POST data to. It's not something that technically "works with the permissions API" but any transaction that is made would indeed trigger the IPN.
If you're building an app for 3rd parties to use, though, and you're passing NotifyURL in your API requests, that will override any IPN configuration each individual merchant using your tool might have setup on their own. This can cause frustration for such users because then their own IPN solution doesn't get hit when they take payments through your app.
If you're going to do that I recommend setting up a way for your users to enter their own IPN URL in your app settings, and then if they have a value, forward the POSTed data to their URL when PayPal sends it to yours. That way both IPN scripts will get hit and process the data accordingly.
I have downloaded sample code from paypal to allow me to use parallel payments via their sandbox accounts. When I run parallel.php, I get redirected to paypal's sandbox login page.
How am I supposed to know "server side" that the payment has been made successfully, so I can update my database records?
I believe you have to work with PayPals IPN system. This will basically send a confirmation to your server that tells you it has gone through.

Paypal lets you register a notification url which is part of the IPN (instant payment notification IIRC) system. So if someone pays by a delayed payment (such as a bank transfer) the transaction will update days later. You need to have an application (web page) on your server that can be called by Paypal with transaction details to update a payment.
You'll need to create an initial transaction record in your system when paypal redirects back to you so refer to their documentation for that. I'd also recommend looking at either OSCommerce or Zen cart for an idea of how they do it as they support the same kind of thing.
