Post a journal entry
Finance module
POST/journal-entries/{id}/postjournalEntries.post
Posts the entry to the ledger. The preparer cannot post it; a closed period refuses it. Requires `Idempotency-Key`; a replay returns the original response. A rule that refuses the request returns 422 with `refusal` and `reason`.
- Requires the capability finance.journal.post.
- OAuth scopes: finance.
- Send an Idempotency-Key header. A replay with the same key returns the original response.
- Error statuses: 400, 401, 404, 409, 422, 429. Errors are RFC 9457 problem details.
