Name-Value Pairs(NVP) is a PayPal Classic API syntax that uses a query-string to pass data

NVP works exactly like a query string (raw POST operations also function like query strings). A sample NVP (minus the necessary authentication data) looks like this

METHOD=GetTransactionDetails&VERSION=109.0&TRANSACTIONID=ABC123
