The Bulk Refunds API provides a quick and straightforward solution for fintech startups looking to automate the process of issuing refunds for multiple transactions simultaneously. By integrating this API, startups can send a batch request containing numerous transaction IDs, prompting the system to initiate refunds directly to the original payers' bank accounts. This functionality is essential for fintech companies that operate at scale and require a reliable mechanism to manage refunds efficiently, minimizing manual intervention and operational overhead.
