Customise your Integration

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.

Update 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.

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

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

Change theme colour

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

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

Change waiting for OTP timeout

PayU will wait for a specified time for the OTP, after which the SDK falls back to the manual OTP screen. The default time is 30 seconds; you may change it to any other duration. PayU recommends you configure the timeout to less than 60 seconds for a better user experience.

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

val payUOtpAssistConfig = PayUOtpAssistConfig() 
payUOtpAssistConfig.waitingTime = 45000 

Disable Auto-Submit OTP flag

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

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

Update merchant response timeout

Merchant response timeout 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, PayU has a response timeout of 10 sec by default. However, if you feel that the surl/furl can take longer than 10 seconds, you can configure this flag.

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

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

Disable or enable vibration after a successful transaction

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

Vibrate permission

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

📘

Tip

You can disable the vibration behavior from PayUOtpAssistConfig also.

Disable merchant summary from UI

You can disable merchant summary from the UI.

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

val payUOtpAssistConfig = PayUOtpAssistConfig() 
payUOtpAssistConfig.shouldShowMerchantSummary=false   

Card BIN eligibility check

You can check the card whether your card bin eligible or not for the OTP on the Merchant App. For more information, refer to the Zero Redirect Eligible Bins API.
