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.

Merchant Logo

You can display your brand logo in the PayU Native OTP Assist SDK to reinforce trust and branding. To set a logo in the SDK, you need to pass the drawable id of the logo image resource from your app.

PayUOtpAssistConfig payUOtpAssistConfig = new PayUOtpAssistConfig(); 
payUOtpAssistConfig.setMerchantLogo(R.drawable.merchant_logo); 

val payUOtpAssistConfig = PayUOtpAssistConfig() 
payUOtpAssistConfig.merchantLogo = R.drawable.merchant_logo 

Theme Colour

Our SDK allows you to change the theme colour, you just need to set this primary colour in your color file.

<color name="otp_assist_primary_color">#fd416d</color>

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.

PayUOtpAssistConfig payUOtpAssistConfig = new PayUOtpAssistConfig(); 
payUOtpAssistConfig.setWaitingTime(45000); 

val payUOtpAssistConfig = PayUOtpAssistConfig() 
payUOtpAssistConfig.waitingTime = 45000 

Auto-Submit OTP Flag

Merchant can enable/disable the auto-submit OTP flow on using the flag below. The default value is set to true.

PayUOtpAssistConfig payUOtpAssistConfig = new PayUOtpAssistConfig(); 
payUOtpAssistConfig.setShouldAllowAutoSubmit(true);  

val payUOtpAssistConfig = PayUOtpAssistConfig () 
payUOtpAssistConfig.shouldAllowAutoSubmit = false 

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.

PayUOtpAssistConfig payUOtpAssistConfig = new PayUOtpAssistConfig(); 
payUOtpAssistConfig.setMerchantResponseTimeout(25000); 
// for 25 seconds timeout 

val payUOtpAssistConfig = PayUOtpAssistConfig() 
payUOtpAssistConfig.merchantResponseTimeout = 25000 // for 25 seconds timeout 

Disable/Enable Vibration after Successful transaction

After the payment gets successful, the user mobile vibrates for 0.5Sec. You just need to Add the VIBRATE permission in your Manifest file.

Vibrate Permission

<uses-permission android:name="android.permission.VIBRATE"/>

You can disable the vibration behaviour from PayUOtpAssistConfig also.

PayUOtpAssistConfig payUOtpAssistConfig = new PayUOtpAssistConfig(); 
payUOtpAssistConfig.setShouldVibrateAfterPaymentSuccess(false);  

val payUOtpAssistConfig = PayUOtpAssistConfig() 
payUOtpAssistConfig.shouldVibrateAfterPaymentSuccess = false 

Card Bin Eligibility Check
