Overview

👉 The Decimal Amount Mode request is used to turn Decimal Amount Mode on or off. This setting determines whether or not payment amounts are provided to the ‘Viva.com Terminal’ application in decimal format.

The client app must implement a mechanism to send messages using Android intents and URI calls and to receive the result in a custom URI callback.

• Decimal Amount Mode request originating from the client app to initiate a request for a decimal amount mode.
• Decimal Amount Mode response originating from the ‘Viva.com Terminal’ application to return the result of a decimal amount mode.

Decimal Amount Mode request

For a typical Decimal Amount Mode request, the client app must provide the following information:

Field	Description	Example	Card terminal support
scheme	The Viva custom URL scheme, the host and the version.	'vivapayclient://pay/v1'
merchantKey	The merchant's key. For successful validation, should not be empty. Deprecated: you may pass any value	'SG23323424EXS3'
action	AmountDecimalMode. For successful validation, should not be empty.	‘amountDecimalMode’
decimalMode	A unique description of the decimal mode option such as 0 for ‘Decimal Amount’ or 1 for ‘No Decimal Amount’	'0'
callback	The URI callback that will handle the result. For successful validation, should not be empty.	'mycallbackschme://result'

The above information elements must create a URI call. i.e.

Intent payIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(
                "vivapayclient://pay/v1"
                + "?merchantKey=""MY_MERCHANT_KEY""
                + "&appId=com.example.myapp"
                + "&action=amountDecimalMode"
                + "&callback=mycallbackscheme://result"
                + "&decimalMode=0"))

payIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

payIntent.addFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
                startActivity(payIntent);

Decimal Amount Mode response

After executing a decimal amount mode request the ‘Viva.com Terminal’ application responds with a decimal amount mode response.

The result is received as a URI in the callback activity intent:

  Uri result = getIntent().getData();

The table below summarises the contents of an approved response.

Field	Description	Example	Card terminal support
callback	The URI callback that will handle the result.	'mycallbackscheme://result'
status	The status of the request.	'success'
