State Combinations

State combinations cases.

Understanding the various possible combination of Payment Transactions that are in the attempted state with the Payment-Attempts states is crucial. Let's simplify them:

Multi-Attempt Transactions

For the payment transactions that allow multiple attempts, we encounter two combinations:

• When a Payment Transaction is in the attempted state, and the Payment-Attempt state is canceled or failed, the payment transaction state remains attempted. That means the transaction is open for another attempt until it either expires (i.e., expired state) or successfully reaches the paid state. In simple terms: attempted state for payment transaction ➕ canceled or failed state for payment attempt ➡ attempted state for payment transaction, until it changed to expired or paid, and the payment transaction can be attempted again

• Alternatively, when a Payment Transaction is in the attempted state and the Payment-Attempt succeeds (i.e., success state), the payment transaction progresses into the paid or authorized state. In simple terms: attempted state for payment transaction ➕ success state for payment attempt ➡ paid or authorized state for payment transaction.

Single-Attempt Transaction

For the payment transactions that do not allow multiple attempts:

• Such transactions do not have an attempted state. Instead, they can either be in a failed or authorized state.
