Required scope: cards:write

The API credential calling this endpoint must be granted the cards category with read & write access.
Scopes are assigned to the credential when it is created or edited in Pliant, not requested when obtaining the access token.
A credential without this scope receives 403 Forbidden with the error code INSUFFICIENT_PERMISSION.

Change the card limit for a given virtual or physical card, as long as the card is not terminated. This is unrelated to the renew frequency of the card.
Meaning you can update the limit of a card with a TOTAL renew frequency (equals no limit renewal) as well as a MONTHLY renew frequency etc.

Additional limits: Use the additionalLimits field to create, update, or remove additional limits on the card in the same request.

• Entries with an id → update the matching existing additional limit.
• Entries without an id → create a new additional limit.
• Existing additional limits omitted from the array → soft-delete (removed).
• Passing null or omitting additionalLimits → leave existing additional limits unchanged.
• Passing an empty array [] → remove all additional limits from the card.

Response: This endpoint returns 204 No Content. To read the updated limit state use GET /api/cards/{cardId} or subscribe to the CARD_LIMITS_CHANGED callback.
