What types of transactions should be tested in the PayPal Website Payments Standard IPN Simulator?
On my website, I would like to process an order using the IPNs sent by PayPal.
Before that happens, I would like to use the IPN simulator on the PayPal developer website ( https://developer.paypal.com/developer/ipnSimulator ) to do some testing.
In the IPN simulator, you can see that we need to select the type of transaction to send the IPN test. There are many examples: "Express Checkout", "Cart Checkout" and "Web Accept".
My site uses PayPal "Website Payment Standard" to accept payment, but I do not know what types of transactions I have to complete.
I tried google but couldn't find any details on this.

If you are working with a Buy Now button, then the txn_type you get will be web_accept. If you are working with other types of buttons, this may be different.
See the list of PayPal IPN Variables for more details , specifically the values for txn_type.
