Create a reloadable card

Authorizations

Authorization
string
header
required

Firebase ID token from /auth or any paid route, sent as a Bearer token: Authorization: Bearer <id_token> (the Bearer prefix is required).

Headers

Idempotency-Key
string

Optional client-generated unique key (a UUID works) that makes this write safe to retry. A retry with the same key within 24 hours returns the recorded response of the original request, marked with an Idempotency-Replayed: true header, instead of performing the write again. Reusing a key with a different body or route is rejected with 422 (code: idempotency_key_reused); a retry that arrives while the original is still running gets 409 (code: idempotency_key_in_progress), so wait a moment and retry with the same key. Keys are scoped to the authenticated account.

Maximum string length: 255

Body

application/json
usd_amount
number
required

Amount in US dollars to load onto the card, minimum $1. Sent as dollars, not cents.

reusable
boolean

Whether the card stays open across charges. Defaults to true; false closes it after the first approved charge.

Response

The newly created card.
