PP Express Checkout need to return FEEAMT variable
I need to return the FEEAMT as display in the FULL RESPONSE like so
RESULT=0&PNREF=EUJP5D317BEF&RESPMSG=Approved&AVSADDR=Y&AVSZIP=Y&TOKEN=EC-56J8431826888421H&PAYERID=CTY5D5PM9UPQN&PPREF=3JY551007S2876314&CORRELATIONID=247541067846&FEEAMT=0.51&TAXAMT=1.93&PAYMENTTYPE=instant&PENDINGREASON=completed
as an individual amount so I can log it in the database. How can I achieve this please as for the life of me I cannot get it to return.
Thanks.
