Example to send amount to a terminal and wait response

[cyberweb-denis]

Dear,

Does anyone have a sample code to send an amount to a terminal and wait for the payment status?

Thank you in advance

Dear Denis,

At the moment you would have to use websockets if you want to listen for the transaction state change. However websockets are not that simple to implement with PHP.

I would recommend to proceed with one of the following options:

• You are using JavaScript in the browser for this. With JavaScript is the creation of websockets etc. relatively simple.
• We are currently working on a way that you can create a transaction on the terminal and listen for the state change via long polling. This will simplify the integration. However this will take at least two months until this option is available.

Ok And have you got a example in javascript ? because if i use the script of the website, i have a error Uncaught ReferenceError: TerminalTillConnection is not defined |<script src="https://app-wallee.com/assets/payment/terminal-till-connection.js" type="text/javascript"></script> <script> var tillConnection = new TerminalTillConnection({url: "wss://app-wallee.com/terminal-websocket",token: "K/5LA1H7ajm+GhyM9LA+9SiBS3M/ABkYxoAJvDhgsY8="}); tillConnection.subscribe("notification", function(payload){     // Display the information on the till. }); tillConnection.subscribe("question", function(payload, callback){     // Display the question on the till and allow the attendant to chose one of the options.     // Call the callback method with the chosen option's identifier as argument.     callback(optionIdentifier); }); tillConnection.subscribe("charged", function(){     // The transaction has been successfully charged. }); tillConnection.subscribe("canceled", function(){     // The payment was canceled. }); tillConnection.subscribe("error", function(error){     // An error occurred during the process of a WebSocket request. }); tillConnection.subscribe("connected", function(){     // The connection has been established. }); tillConnection.subscribe("disconnected", function(){     // The connection has been disconnected or lost. }); tillConnection.connect();| Le 1/09/20 à 21:14, thomashunziker a écrit :

Hi @cyberweb-denis

You need to make sure, that terminal-till-connection.js is loaded before you run the actual commands. You can do this by wrapping the calls in a function and invoke it after the DOM is ready:

function openConnection() {
    var tillConnection = new TerminalTillConnection(...);
    ...
}

if (document.readyState != 'loading'){
    openConnection();
} else {
    document.addEventListener('DOMContentLoaded', openConnection);
}

Hello The javascript is loaded but always the same Uncaught ReferenceError: TerminalTillConnection is not defined It's very strange Le 2/09/20 à 09:45, schurter-wallee a écrit :
