New feature to simulate transaction failure scenarios on the sandbox environment: Every transaction created with an amount ending in 9 will automatically fail during the processing flow.
As of 2024-07-15, to deliver more performance from our API, all transactions will be processed asynchronously, therefore a new transaction status has been created: PROCESSING. With this change, transactions of method BANK_INSTRUCTION and REFUND will initially have the endToEnd attribute set as null and will be filled after the state transition to PROCESSING.
