Integrating Instant payment Notification of PayPal in ADF - paypal

I am building a application in which I want to integrate a payment gateway of PayPal. After the payment is successfully it should update a database value.
Someone suggested for using IPN (Instant payment Notification) of PayPal.
But I could not find any work around to do this.
I can use html/jsp/jsf but not php.

There is a Java code sample for IPN:

That should hopefully work for you.

PayPal IPN empty when buying by card

I have tested a PayPal IPN on sandbox. It works without issue. I tested it using the demo PayPal account. Now I have moved live I cannot test with a PayPal account, as I only have one. So I tried using a card. The payment is successfully made. However, the IPN is empty.
I don't have any PHP errors for the IPN call. The IPN URL defined in Notifications -> Payment Notifications on my live account is correct.
The payment is made using PayPal Smart Checkout: https://developer.paypal.com/docs/checkout/#how-the-buttons-work
Does PayPal not use IPNs when buying by card?
What do you need IPN for? That is a very old service.
Use a server-side integration for the PayPal Checkout. Here's the UI: https://developer.paypal.com/demo/checkout/#/pattern/server
You'll need two corresponding routes on your server, one for 'Set Up Transaction' and one for 'Capture Transaction', documented here: https://developer.paypal.com/docs/checkout/reference/server-integration/

Testing Recurring payment in paypal sandbox

I have integrated paypal sandbox but how can i use paypal recurring payment procedure. which parameter is required for recurring and how can i use web hook for recurring.If any suggest me how to use paypal sandbox recurring and provide best solution.
Which type of recurring is being used?
If you are implementing recurring using NVP/SOAP API, kindly refer to the below. Kindly note that webhook is not compatible with NVP/SOAP API
a. Using Express Checkout - https://developer.paypal.com/docs/classic/api/merchant/CreateRecurringPaymentsProfile_API_Operation_NVP/
b. Using PayPal buttons- https://developer.paypal.com/docs/classic/api/button-manager/BMCreateButton_API_Operation_NVP/
for notifications, you can use IPN to get notifications every time a payment is made
https://developer.paypal.com/docs/classic/ipn/integration-guide/IPNIntro/
If you are implementing using REST API, webhook is used for receiving notifications. Refer to the links below
a. https://developer.paypal.com/docs/api/payments.billing-agreements
b. https://developer.paypal.com/docs/api/webhooks/

Paypal IPN for subscription agreement

I have integrated Paypal subscription plan, and subscribing the plan in rails app. Now I am looking to integrate webhooks for paypal payments. I am really struggling hard to make paypal work. This is my third question related with Paypal subscription, however I have solved earlier questions by myself. But could do better if there was good documentation in paypal.
I found there are IPN for subscription/recurring payment but I can not find the field with which I can relate the IPN with existing subscription. I am storing subscription_id i.e. agreement_id but in IPN i am not able to find agreement_id.
Please suggest what to do.
Thanks in Advance.
You can put the agreement_id value in the custom field. You should get the custom field back during each IPN.

PayPal Donation/Giving API incontext

how do I make donation paypal api call incontext? There are documentation for integrating the donate button, but it opens a new window. Trying to figure out how to build the in-context experience for the donation/giving API calls.
I found the answer!
PayPal automatically takes care of donation/charity when the receiver's email is tied to 501c3 organization.
And for the incontext experience, just followed the documentation of dg adaptive payments flow. Here is the guide for sample code - https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_api_APIntro

GetRecurringPaymentsProfileDetails works for both Express Checkout as well as Website Payments Pro recurring payment profiles.
