API / Reference / Card Transactions

Post card transaction

POST https://api.light.inc/v1/card-transactions/{transactionId}/post

Posts a card transaction to the ledger

Requires status CAPTURED or REFUNDED (CARD_TRANSACTION_CANNOT_BE_POSTED otherwise), a ledger account and a tax code on every line, and every required custom property. Posting writes the lines to the ledger plus an offsetting entry on the ledger account that represents the card balance account; when the transaction currency differs from the entity's, an exchange rate for the posting date must exist. Afterwards status is POSTED and editStatus ALL_EDITS_LOCKED; use reset to edit again. Company-admin or AP-clerk roles only; cardholders cannot post.

    ⚠️ This enum is not exhaustive; new values may be added in the future.
