B4A Library Paytm

Hello all ,
I did this wrapper for a guy in this forum (we agreed on $60) he informed me that the library is working but he asked to get some time , I gave him a few months but he never replied or PAID anything ( now he reads my whatsapp messages but does not reply ).

'#Region  Project Attributes
    #ApplicationLabel: Paytm Example
    #VersionCode: 1
    'SupportedOrientations possible values: unspecified, landscape or portrait.
    #SupportedOrientations: unspecified
    #CanInstallToExternalStorage: False
#End Region

#Region  Activity Attributes
    #FullScreen: False
    #IncludeTitle: True
#End Region

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.
    Private paramMap As Map
End Sub

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
    Private paytmservice As Paytm
    Private cha As String = "WAP"
    Private n As String
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    paramMap.put( "MID" , "yourMID")
    paramMap.put( "ORDER_ID" , "order1"&n)
    paramMap.put( "CUST_ID" , "cust123")
    paramMap.put( "MOBILE_NO" , "7777777777")
    paramMap.put( "EMAIL" , "[email protected]")
    paramMap.put( "CHANNEL_ID" , cha)
    paramMap.put( "TXN_AMOUNT" , "100.12")
    paramMap.put( "WEBSITE" , "WEBSTAGING")
'    // This Is the staging value. Production value Is available in your dashboard
    paramMap.put( "INDUSTRY_TYPE_ID" , "Retail")
'    // This Is the staging value. Production value Is available in your dashboard
    paramMap.put( "CALLBACK_URL", "https://securegw-stage.paytm.in/theia/paytmCallback?ORDER_ID=order1"&n)
Dim order As PaytmOrder
End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub
Sub paytm_someuierroroccurred(inErrorMessage As String)
    Log("B4A: paytm_someuierroroccurred")
End Sub
Sub paytm_ontransactionresponse(inResponse As Map)
    LogColor("B4A: paytm_ontransactionresponse BEGIN",Colors.Blue)
    For Each key In inResponse.Keys
    LogColor("B4A: paytm_ontransactionresponse END",Colors.Blue)
End Sub
Sub paytm_networknotavailable
    Log("B4A: paytm_networknotavailable")
End Sub
Sub paytm_clientauthenticationfailed( inErrorMessage As String)
    Log("B4A: paytm_clientauthenticationfailed")
End Sub
Sub paytm_onerrorloadingwebpage(iniErrorCode As Int ,  inErrorMessage As String,  inFailingUrl As String)
    Log("B4A: paytm_onerrorloadingwebpage")
End Sub
Sub paytm_onbackpressedcanceltransaction
    Log("B4A: paytm_onbackpressedcanceltransaction")
End Sub
Sub paytm_ontransactioncancel( inErrorMessage As String,inResponse As  Map )
    Log("B4A: paytm_ontransactioncancel")
End Sub

As it seems India specific I don't know whether my sample is working or not but it might give you some hint

Thank you for your efforts!
Many of our clients have been wanting Paytm as a way of payment for quite some time now.
I am currently waiting for the Paytm credentials. I'd update you once I get the login details.
