}Update Dispute
Updates the evidence on a dispute, and optionally submits it to the card network.
Saves the provided evidence fields, leaving any omitted fields unchanged; a file field sent as "" is cleared. File fields reference Flex file IDs that must have purpose dispute_evidence; they are resolved to the underlying card-network files before submission. When submit is true, the evidence is finalized and submitted to the network to contest the dispute — evidence cannot be edited after submission.
The dispute must be in a needs_response or warning_needs_response status.
