Stripe processing_error — recovery guide

processing_error is Stripe's way of saying "something went wrong in the payment pipeline, but not a hard decline." The issuer's system, Stripe's routing, or an intermediate network could all cause it. Unlike most decline codes, this one is usually transient.

• Issuer outage — the bank's auth system is temporarily unreachable or slow.
• Network timeout — the authorization request timed out somewhere in the card networks.
• Card data corruption on save — rare but happens; re-collecting the card fixes it.
• Fraud tooling false positive — some banks return processing_error instead of card_declined when their fraud engine wants a second look.

1. First retry: +15 minutes. ~50% clear at this stage.
2. Second retry: +24 hours. Another ~25% clear.
3. If still failing at +48h: treat it as card_declined — email the customer, include a Billing Portal link, ask them to try a different card.
4. Don't spam retries — after 3 attempts, you're just hitting the bank with requests it's going to keep failing.

If you see the same customer getting processing_error 3+ times in a row, the bank is probably masking a real decline reason. Treat it like card_declined: email the customer, ask them to try a different card or contact their bank.
