Change a multi-use card's total spending limit. Raising it reserves the extra amount from the user's cash balance (top up with add_funds if short); lowering it frees the difference, but the new limit can never go below what the card has already spent. Single-use cards cannot be resized.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| card_id | string | yes | The multi-use card ID to resize. |
| approval_id | string | no | Approval id from a prior approval_required response, once the user has approved. Only for cards created through ANOTHER app: first call without it (the user is emailed an approve link), then retry with it. |
| spend_limit_cents | number | no | The new TOTAL spending limit in cents (minimum 100). This is the lifetime cap, not a delta: a card that spent $20 of a $50 limit, resized to 8000, can spend $60 more. |
| new_limit_cents | number | no | Deprecated alias for spend_limit_cents. Prefer spend_limit_cents (matches the docs and the REST API). |
