Getting error "You have exceeded the maximum transaction amount set by your bank" when calling Google Pay intent from my android app

Question

I am facing this weird problem with my Google pay integration in android app. When I am sending an amount more than 2000(INR) I am getting the error "You have exceeded the maximum transaction amount set by your bank" even though I have not transacted any amount. And when I try to send amount directly from Google pay it works. It is also working for the amounts below 2000(INR) but not for more than that.

Here is code iiiiii

  val uri: Uri = Uri.Builder()
        .scheme("upi")
        .authority("pay")
        .appendQueryParameter("pa", MY_UPI_ID)
        .appendQueryParameter("pn", MY_USER_NAME)
        //.appendQueryParameter("mc", "1234")
        //.appendQueryParameter("tr", "123456789")
        .appendQueryParameter("tn", "test transaction note")
        .appendQueryParameter("am", "2500.00")
        .appendQueryParameter("cu", "INR")
        //.appendQueryParameter("url", "https://test.merchant.website")
        .build()
    
    
    val intent = Intent(Intent.ACTION_VIEW)
    intent.data = uri
    intent.setPackage(GOOGLE_PAY_PACKAGE_NAME)
    startActivityForResult(intent, PAY_REQUEST_CODE)

I have read a lot of blogs, docs but didn't found any solution. Any help or suggestions?

Answer 1

Uri uri = Uri.parse("upi://pay").buildUpon()
     .appendQueryParameter("pa", upiId)  // google pay business id
     .appendQueryParameter("pn", name)
     .appendQueryParameter("mc", "")            /// 1st param - use it (it was commented on my earlier tutorial)
     //.appendQueryParameter("tid", "02125412")
     .appendQueryParameter("tr", "25584584")   /// 2nd param - use it (it was commented on my earlier tutorial)
     .appendQueryParameter("tn", note)
     .appendQueryParameter("am", amount)
     .appendQueryParameter("cu", "INR")
     //.appendQueryParameter("refUrl", "blueapp")
     .build();

there are two modification you need to do.

1. use Google pay business App ID only
2. use "mc" and "tr" param in intent call.

"mc" - merchant code(it can be blank). "tr" - transaction refer id(it can be any random number). Working Reference Post here
