How to respond, by gateway

Stripe

Stripe specifics for this dispute

• Deadline: 7-21 days depending on card network (check the Stripe dashboard deadline for your dispute)
• Where to submit: Stripe Dashboard → Payments → the disputed charge → Submit evidence. Stripe also supports automated dispute evidence with webhooks.
• Fee impact: Stripe charges a $15 fee when the dispute is received, kept win or lose. If you submit evidence (counter the dispute), a second $15 applies and that one is refunded when you win.
• Stripe quirk: Stripe requires evidence fields submitted via their structured form or API fields (uncategorized_text for anything else).

PayPal

PayPal specifics for this dispute

• Deadline: 10 days to respond to an 'Item Not Received' or 'Significantly Not As Described' claim
• Where to submit: PayPal Resolution Center → the case → Add Response. PayPal Seller Protection can shift liability entirely if shipping proof meets their terms.
• Fee impact: PayPal keeps the original transaction fee even on a refund; no separate chargeback fee for most seller cases.
• PayPal quirk: PayPal disputes are claims under their own flow, not card-network chargebacks, until the buyer escalates. Seller Protection criteria: proof of delivery to the address on the transaction, online tracking, signature for high-value orders.

Braintree

Braintree specifics for this dispute

• Deadline: network deadline shown per dispute (typically 7-14 days); Braintree emails a new-dispute notification
• Where to submit: Braintree Control Panel → Transactions → Disputed → Submit Evidence. Evidence text fields map to network evidence types.
• Fee impact: $15 per dispute (US), waived if the dispute is won.
• Braintree quirk: Braintree (a PayPal service) passes network chargebacks through under raw network rules. The evidence categories follow the card network, not Braintree's own taxonomy.

Adyen

Adyen specifics for this dispute

• Deadline: defense period shown in the Customer Area per dispute (usually 14-21 days)
• Where to submit: Adyen Customer Area → Transactions → Disputes → Defend. Adyen supports API-driven defense document upload (disputes/defend endpoints).
• Fee impact: Adyen passes the network chargeback fee through; amounts vary by scheme and region.
• Adyen quirk: Adyen's Defense Reasons map each network code to structured defense types. Choose the one matching your evidence, or Adyen defaults to a generic defense that loses specificity.

Frequently asked questions

Is 4863 the same as fraud?

Not necessarily. 4863 means the cardholder does not recognize the charge on their statement, which is often a descriptor problem rather than true fraud.

What fixes a descriptor problem?

A clear billing descriptor (recognizable business name plus order number in the receipt) and a purchase confirmation email. Many 4863 disputes are withdrawn once the buyer identifies the purchase.
