When using the PayPal Show Dispute Details API, I have some responses where adjudications are missing a reason. Happens rarely but has been a consistent issue.

My current best guess is that the the chargeback happened externally (through their credit card) and PayPal can’t supply a reason.

If anybody can confirm or enlighten me, would greatly appreciate it!

What I’m seeing from my problem dispute.

      {
         "adjudication_time" : "XXXX-XX-XXTXX:XX:",
         "dispute_life_cycle_stage" : "CHARGEBACK",
         "type" : "PAYOUT_TO_BUYER"
      }
   ],

Expecting something similar to.

   "adjudications" : [
      {
         "adjudication_time" : "XXXX-XX-XXTXX:XX:",
         "dispute_life_cycle_stage" : "CHARGEBACK",
         "reason" : "VALID_PROOF_OF_DELIVERY",
         "type" : "DENY_BUYER"
      }
   ],

Read through documentations. Reason is not required. Reached out on PayPal’s forum.
