max_feesstringRequired

The estimated max fees for the requested transaction attributes, in base units. We recommend using this amount as max_fee when creating a transaction request through POST /transactions for the same transaction attributes. Max fees represent the highest possible fee amount you will pay to broadcast this transaction. The final fees, calculated once the transaction is approved by the last Operator, might be lower, but will never exceed that amount. See https://help.vault.ledger.com/developer-portal/content/transactions/tx/ for details

max_fees_buffer_factornumberRequired

Network fees can fluctuate between the creation of a transaction request and the submission of the transaciton to the network, after all the approvals have been collected. Ledger Vault adds a buffer to the network fees required for the selected transaction speed. See https://help.vault.ledger.com/developer-portal/content/transactions/tx/
