To set up product sync using PayPal, click on the sales module that you would like to configure products for, and select Yes for "Use Webhooks?"
Then type in the name and price of the product you would like to log as a sale. Drag a connection from the page that leads to this order/upsell page, as well as a connection to the page that the user goes after buying this product. If you would like to add in more products, click "Add New Product" at the bottom right.
IMPORTANT: If you have an ampersand (&) in your product name you will need to save them with the ASCII characterization version of that delimiter, %26. So if your product name is "books & novels" you would enter it as "books %26 novels". Also, Please keep in mind that PIPE (|) character strings are not allowed in the Product Name field to properly work with our webhooks.
NOTE: In order for sales to be logged correctly, the product names and prices will need to match exactly how they're set up inside PayPal.
Copy the webhook URL generated.
Go to PayPal and click on Profile and Settings under the Profile tab.
Go to “My Selling Tools”.
Under “Instant Payment Notifications”, click “Update”.
Edit your IPN settings.
Paste the IPN URL you copied earlier.
Then make sure “Receive IPN messages (Enabled)” is checked.
Click “Save” and that’s it!
This IPN only needs to be setup once per PayPal account for all of your campaigns tracked.
As soon as PayPal processes a transaction it will send us the IPN with all the necessary information we need to credit a sale!
IMPORTANT: When testing sales with PayPal, please do not use the IP Spoofing feature, as it will conflict with the IP address that their webhooks send through. Instead, please use your real IP address when testing sales.
