Authenticate with an API key using the Authorization header: `Bearer brz_...` servers: - url: https://api.breezing.io/v1 security: - BearerAuth: [] paths: /transactions/ungroup-trades: post: tags: - Transactions summary: Ungroup trades description: >- Dissolve one or more trades back into plain transactions, the API equivalent of "Ungroup" in the dashboard and the reverse of POST /transactions/group-trades. Pass the transaction id of ANY leg: the whole trade it belongs to is resolved via its exchangeId and every leg reverts to a plain row (type="transaction", exchangeId=null). The legs themselves are not deleted or altered otherwise; a trade that was consolidated from more than two legs stays as its two synthesized rows, they simply stop being linked as a trade. Returns 404 if any transaction is not found, 400 NOT_A_TRADE if any id is not part of a trade (null exchangeId; this includes ids whose trade was already ungrouped, so a retry after success reports NOT_A_TRADE rather than succeeding twice), and 409 if ANY leg of a resolved trade is locked or currently processing, including legs you did not pass (a partial ungroup would corrupt the pair, so the whole trade must be mutable). Duplicate IDs are deduplicated server-side. Balances, cost basis and net gain/loss are NOT recomputed automatically; run POST /ngl/calculate when ready. parameters: - schema: type: string description: >- Organization ID.
