# Batch upsert transactions

`BatchUpsertTransactions`

`POST /api/transactionportfolios/{scope}/{code}/transactions/$batchUpsert`

- [OpenAPI fragment](https://www.lusid.com/docs/api/lusid/endpoints/transaction-portfolios/BatchUpsertTransactions.json)

Create or update transactions in the transaction portfolio. A transaction will be updated
if it already exists and created if it does not.

Each request must be keyed by a unique correlation id. This id is ephemeral and is not stored by LUSID.
It serves only as a way to easily identify each transaction in the response.

Note: If using partial failure modes, then it is important to check the response body for failures as any failures will still return a 200 status code
