Cashback eligibility and reward calculation

The Cashback Reward Eligibility Service is responsible for evaluating whether a transaction qualifies for a Cashback Reward. Once a transaction is authorized by PayCredit, an event is generated to trigger this service, which checks the transaction against predefined cashback eligibility criteria. If the transaction meets the required conditions, the system records the eligibility and updates the reward balance.

This feature enhances the automation and efficiency of cashback processing by:

• Ensuring real-time evaluation of transaction eligibility for cashback rewards.
• Providing a seamless mechanism to update reward balances.
• Reducing manual intervention in the cashback validation process.
• Enabling bank clients to receive timely notifications of eligible transactions. (Future)
