Changing `type` to one with a fixed direction (collection: debit; payment, bank commission: credit) moves the amount to that side. A transaction recorded against a patient only accepts `description`, `invoice_number`, `payment_method` and `transaction_date`; anything else is refused with `PAIRED_TRANSACTION_IMMUTABLE`. ## OpenAPI ````yaml put /v1/bank-accounts/{accountId}/transactions/{transactionId} openapi: 3.1.0 info: title: Flextell API version: 0.0.1 description: >- Flextell REST API referansı.
