Create split transactions

This endpoint creates two or more child transactions that are branched from a previous transaction. This endpoint allows you to link multiple categories, descriptions, and amounts to a parent transaction. <br></br><br></br> When a split transaction is created, the parent transaction's has_been_split field will automatically be updated to true and the child transactions' parent_guid will have the transaction guid of the parent. The total amount of the child transactions must equal the amount of the parent transaction. Once a transaction has been split it can't be split again. <br></br><br></br> To re-split a transaction, it must first be un-split. This can be done by calling the Delete Split Transactions endpoint. Calling this endpoint will delete the existing child transactions and update the parent transaction's has_been_split field to false. You can then re-split the parent transaction by calling Create Split Transaction again.
