Attach documents to a dispute response

Open an active dispute. Add relevant synthetic PDF, PNG or JPEG files, each up to 2 MiB. At most ten files may be uploaded per case. Files are encrypted and unavailable to readers while awaiting the malware scan. A clean scan does not establish authenticity.

Exclude any document that should not accompany your response. Submit only after all included documents finish scanning. Submission records the exact accepted documents. After submission, the response and its evidence list cannot be replaced through the merchant screen.

Authorized independent staff can review available documents through the private case viewer. Downloads are audited. The local preview retains files for seven days; this is not the production retention policy. If a file expires or cannot be opened, staff must resolve the evidence gap before making a decision.
