Customization
The Native OTP Assist SDK provides several customization options allowing you to make the SDK closer to the look & feel of your app and work as per your business requirements.
Following customizations are allowed:
Update merchant Logo.
Change the theme colour.
Change waiting time for the OTP.
Disable Auto submit OTP Flag
Update merchant response timeout for fallback.

Waiting for OTP timeout
We wait for a specifed time for the OTP after which the SDK falls back to the manual OTP screen. The default time is 30s; you may change it to any other duration. We recommend keeping it less than 60s for better user experience.

Merchant Response Timeout
This is the duration PayU will wait for merchant surl/furl to load before passing the transaction response back to the app. If merchant surl/furl pages take longer to load then by default PayU has a response timeout of 10 sec. However, if merchants feel that their Surl/Furl can take longer than 10 seconds then they can set this flag.
Java
Kotlin

PayUOtpAssistConfig payUOtpAssistConfig = new PayUOtpAssistConfig();

payUOtpAssistConfig.setMerchantResponseTimeout(25000);

// for 25 seconds timeout
