php - PayPal Rest API - Live payments fail, sandbox works -

i've built job listing website can pay publish own job listings. working expected, job searching functionality , user registration/profile system. it's live , looks great!

but we've switched paypal on live credentials, payment not working. working sandbox... have followed rest api closely possible, allowing optional fields , requiring required ones, sending proper type formats (integer, strings , objects) defined in api documentation...

still, attempts payment gets notification of "credit card refused". i have contacted paypal , have been through back-and-forth trying resolve issue, persist issue not on end.

i'm going include debugging information below in email paypal well, maybe here has more experience type of issue , can me out.

here json code submitted using my own personal credit card (sensitive info removed, of course):

{"intent":"sale","payer":{"payment_method":"credit_card","funding_instruments":[{"credit_card":{"number":"**hidden**","type":"mastercard","expire_month":10,"expire_year":2016,"cvv2":"**hidden**","first_name":"radley","last_name":"sustaire","billing_address":{"line1":"**removed**","city":"veneta","postal_code":"97487","country_code":"us","state":"or"}}}]},"transactions":[{"amount":{"total":"1.00","currency":"usd"},"description":"purchased product: 30-day free job listing"}]} 

and here result received paypal, curl (in object layout):

after looking @ logs specific debug_id, showing standard payment decline. it's not integration issue. if need more specific information, you'll need contact customer support , have them payment attempts card used.
