Creates a credit card entry with its lines.

POST /banking/credit-card-entries

Group: Banking › Credit Card Entries · Operation ID: createCreditCardEntry

The response contains only the new entry's id. Read the record with GET banking/credit-card-entries/:id.

entityId, creditCardAccountId, transactionDate and at least one line are required. Every line amount is a decimal in the entry currency. No line may be zero, and the lines may not sum to zero.

When currency is omitted the account's own currency is used. When supplied it must match the account's, or the call fails with CURRENCY_MISMATCH.

The posting period is resolved across every book the entity posts to. A transaction date whose period is closed, or open in some books and closed in others, fails with POSTING_PERIOD_NOT_OPEN.

attachments names already-uploaded files. On a tenant that requires an attachment, omitting them fails with ATTACHMENT_REQUIRED.

Parameters

Name	In	Type	Required	Description
`Api-Version`	header	`"v1"`	yes	The API version this request targets, named by its public identifier. Required on every request; omitting it, or naming a version this company does not have, is answered with 400. This document describes version `v1`.
`Idempotency-Key`	header	string	no	An opaque caller-chosen string (1-255 characters) that makes this request safe to retry. Repeating the same key with an identical request body replays the original response instead of re-executing - but only once that original request succeeded; a failed attempt re-executes on retry. Repeating the key with a different body is answered with 422. A key still in flight is answered with 409 - as is a key whose original request was interrupted before it finished, for a few minutes afterwards, until that attempt is presumed dead. A completed response stays replayable for 24 hours. The key is scoped to the caller, not to the action: reusing it for a different action is answered with 409 or 422 rather than treated independently. On read actions this header is ignored. On write actions that cannot offer the guarantee it is answered with `400 IDEMPOTENCY_NOT_SUPPORTED` rather than silently ignored.
