PayPal：使用API​​在实时模式下仪器下降

Question

We're currently using the rest API for PayPal (PHP) and everything was working fine in the sandbox. When we went live we continue to get the following message:

{"name":"INSTRUMENT_DECLINED","details":[],"message":"The instrument presented  was either declined by the processor or bank, or it can't be used for this payment.","information_link":"https://developer.paypal.com/docs/api/#INSTRUMENT_DECLINED","debug_id":"8ad80896530bd"}

What does this mean and more importantly is there a reason this is not being caught as an exception in the php SDK. It seems to pass through without issues (using the exact same code as in the sample file for executing a payment). Is there a way to catch this?

Answer 1

Sounds like the payment method was turned down by the bank, or is not allowed for the attempted purchase. For instance prepaid debit cards are often now able to complete certain payments, and many cards are restricted geographically.

everything was working fine in the sandbox

The sandbox doesn't actually check with the bank whether a card is good, so it wouldn't have thrown the same error. The sandbox is for testing whether the code paths work as intended. The problem is not with your script.
