Today I recieved this message:

"We didn't receive all the information we needed from this app to complete your purchase. You haven't been charged for this purchase, so please try again. If you keep seeing this error, contact the app developer."

And I don't understand what the reason. Yesterday I think it worked fine.

JS request

var obj = {
action: "purchaseitem"
method: "pay"
product: "https://www.sozzial.com/fb/subscriptions.html"
quantity: "50"
quantity_max: 5000
quantity_min: 1
request_id: "3MJhipp24N0THO+eExGvsdoRZKsF+8vsAD3Po1NRrqCTKSwlDKRO4Wytwh+gP1UrloU37lOJC9cXF7FOLSBAosoXIugOrNtAEMOobnxm6Bzhi7+eWIASl4jA1lNcG3AndHyNfv0OI+IPLXspH76QslI099c="
