Charge the saved card to top up prepaid balance

Amount to charge the saved card, in cents. The flat floor is $25 and the default per-deposit cap is $500 (raised to an approved monthly spend limit). While the org has usage running the endpoint requires at least one hour of the current burn; read the exact figure from Balance.minDepositCents rather than re-deriving it.

Optional Fingerprint event id (see DeviceSignals).

Optional Fingerprint visitor id (see DeviceSignals). Recorded and clustered. A device that puts the account on a verification hold gets 403 ACCOUNT_PENDING_VERIFICATION, or 403 VERIFICATION_UNAVAILABLE when the hold could not be recorded; every other verdict is observe-only.

Client-generated id for this logical deposit; reused verbatim on retry so a network/client retry can't double-charge. Optional: the server generates one if absent (then retries won't dedupe).

Set only when status is requires_action (on-session SCA).

Why the card was declined, set when status is requires_payment_method and Stripe gave a reason: a Stripe decline code (https://docs.stripe.com/declines/codes) such as insufficient_funds, expired_card, incorrect_cvc or card_velocity_exceeded. A decline Stripe asks merchants not to explain (fraudulent, lost_card, stolen_card, merchant_blacklist) is reported as generic_decline. New codes can appear, so treat an unknown one as a generic decline.

Set with clientSecret: the Stripe publishable key Stripe.js needs to confirm the PaymentIntent on-session.

Stripe PaymentIntent status. "succeeded" → credit lands via webhook; "requires_action" → complete SCA on-session with clientSecret; "requires_payment_method" → the card was declined.
