Send Logs request

An overview of the Send Logs request message for iOS.

Our ‘Viva.com Terminal’ application (tap-on-phone) supports Apple Tap to Pay in the the UK, the Netherlands, France, Austria, Czech Republic, Ireland, Romania, and Sweden, Italy & Germany.

Overview

👉 The Send Logs request is used to send the logs of the Viva POS App to the Viva payment platform. This is particularly useful for troubleshooting purposes.

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

Send Logs request

For a typical Send Logs request, the client app must provide the following information:

Field Description Example
scheme The Viva's 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'
appId The client app ID. For successful validation, should not be empty. 'com.example.myapp'
action Cancel transaction. For successful validation, should not be empty. 'sendLogs'
callback The URI callback that will handle the result. For successful validation, should not be empty. 'interapp-callback’

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

   // USE LIKE THIS
    func sendLogs() {
        let sendLogsUrlString = Constants.sendLogsUrlString //"vivapayclient://pay/v1?callback=interapp-callback&merchantKey=SG23323424EXS3&appId=com.vivawallet.InterAppDemo&action=sendLogs"
        (UIApplication.shared.delegate as? AppDelegate)?.performInterAppRequest(request: Constants.sendLogsUrlString)
    }

Send Logs response

After executing an abort transaction, the ‘Viva.com Terminal’ application responds with an abort response result to indicate if the abort request has been successful or not. Also, we should state that the response from the abort action is actually a response of a failed transaction.

The result is received as a URI in the application(_:open:options:) method on the AppDelegate file.

The table below summarises the contents of a successful response.

Field Description Example
callback The URI callback that will handle the result. 'interapp-callback://result'
status The status of the request. 'success'
message A string containing information about the send logs status. 'Logs sent!'
action Send logs. 'sendLogs'

A send logs response result looks as follows:
