# API eMandate success rate




## API eMandate authorisation success rate optimisation



The success rate of API eMandate authorisation is a function of multiple factors, including:

1. Intent - whether the customer fully intended to complete the check-out. Customers may simply abandon the checkout by closing the browser.
2. Internet connectivity - whether the customer had a stable internet connection. Customers may loose internet connectivity during the checkout.
3. NPCI rejections - whether the request or response has passed technical validations in ONMAGS.
4. Destination bank rejections - whether the destination bank website is correctly declining the authorisation due to an invalid attempt e.g. wrong account number.
5. Other technical errors: whether the destination bank website is functioning correctly. Sometimes they may be having a temporary technical issue.
