All transactions in the platform are executed asynchronously, that is, once you request a new Transaction it is registered as
pending and sent to the execution pipeline. Whenever the transaction state changes a new Postback is sent and the
transaction.status field gets updated.
You may check the
state.additionalData field from the last
transaction.states entry to get specific details about the transaction failure.
All cards transactions are internationally standardized using ISO 8583. Whenever a Card transaction is processed, a Result Code is emitted both on the POS machine and the Web Gateways. This code is used to identify possible scenarios where the physical or virtual cards may not be working.
