Please change the following configurations based on your requirements.
setServer (Server server) - Use this to test the APIs on the merchant Integration environment. Default value is Server.PRODUCTION
PaytmSDK.Builder builder =
PaytmSDK.builder(context, mid, orderId, txn, amount, this);
if(isStaging) {
PaytmSDK.setServer(Server.STAGING)
}
else{
PaytmSDK.setServer(Server.PRODUCTION)
}
PaytmSDK paytmSdk = builder.build();
setAssistEnabled (boolean enablePaytmAssist) - Use this to enable Paytm Auto Assist feature (Auto reading OTP). The default value is False. This method is only available in the sdk version com.paytm.nativesdk:core-ep:1.0.0. Should be used only in case merchant wants to use Paytm Assist.

override fun onResponse(response: VPAValidateResponse?) {
if (response?.isValid == true) {
Toast.makeText(applicationContext, "VPA Validated", Toast.LENGTH_SHORT).show()
} else {
Toast.makeText(applicationContext, "VPA Not Validated " + response?.resultMsg, Toast.LENGTH_SHORT).show()
}
}
override fun onErrorResponse(error: VolleyError?, errorInfo: VPAValidateResponse?) {
Toast.makeText(applicationContext, "Error in API", Toast.LENGTH_SHORT).show()

Attribute | Description |
---|---|
vpaId | VPA Id that needs to be checked |
upiNumber | Unique ID between 8-11 digits mapped to VPA. 10 digit is reserved for mobile number. 8 and 9 digit for custom numbers Note: Subscription is not supported with upiNumber flow. |
