IPNs provide an effective way to keep you up-to-date on all transaction events in real time. Transaction events include actions like authorizations, payments, refunds and more.
Whenever one of these events occurs, the IPN will provide you with basic details about the event, such as the price, product, shipping address details, payment method, and shopper information.
IPNs and Webhooks
Some payment processors use the term Webhooks when referring to notifications. Webhooks and IPNs are essentially equivalent.
Here are some ways you might use IPNs:
- Make sure your accounting records are updated when a payment is made
- Take action when a chargeback is processed
- Send a subscription reminder email to a customer when their subscription is due for renewal
- Update your customer database when a subscription is processed
IPNs are automatically transmitted via an HTTPS POST request to a unique URL on your site's server, which you will define. IPNs are triggered by an event such as an authorization, payment acceptance, or refund confirmation and are sent as soon as the event is complete.
To enable IPNs, you will need to set up a server and URL on your side and then configure IPNs in your BlueSnap account. See Setting up IPNs.
