This ensures the API can detect and prevent repeated submissions. Additionally, before processing a payment check the transaction status using <A href="https://ahbonus-kaart.nl/" target="_self"><STRONG>CyberSource’s reporting API</STRONG></A> to see if a previous request succeeded. Logging all API calls with timestamps and references can also help track potential duplicates. Combining these practices reduces errors and ensures safe, reliable payment processing.</P> Mon, 15 Dec 2025 21:11:41 GMT https://community.developer.cybersource.com/t5/Integration-and-Testing/How-to-handle-duplicate-transactions-with-CyberSource-API/m-p/94713#M58573 oliviawilliam 2025-12-15T21:11:41Z https://community.developer.cybersource.com/t5/Integration-and-Testing/How-to-handle-duplicate-transactions-with-CyberSource-API/m-p/94714#M58574 <P>Great explanation!
