Application Overview

Transact is launched by opening a URL in any browser. The URL carries the account identifier, configuration name, and optional parameters that control what the agent sees, how the payment is processed, and where results are sent.

https://{envDomain}.transact.aiphoria.net?account={account}

• sandbox — global sandbox
• uk — production UK

Everything the application does — which fields appear, which PSP is called, how the agent correlates a call, and what happens after submission — is driven by a configuration stored against the account. The sections below walk through the application screens, explain the configuration structure, and list every input parameter.

1. Application Walkthrough

Authorisation

Before reaching the capture screens, an agent must be authorised. Transact supports two authorisation modes:

• Dynamic agent authorisation — If the username parameter is supplied in the launch URL and the account is enabled for dynamic agent authorisation, the agent is authenticated automatically and taken straight to the application. No login screen is shown.
• Login screen — If username is not supplied, or the account is not enabled for dynamic agent authorisation, the agent is redirected to the login screen.

Login screens

When dynamic agent authorisation is not active, Transact shows a login form. The fields displayed depend on which parameters are already in the URL.

Login with account in the URL

When the account parameter is included in the launch URL, the login form pre-fills the account and only asks for Username and Password.

Pay by Phone

Pay by Phone walkthrough

The agent correlates a live call, the customer enters card details via DTMF or speech, and the agent submits the payment.

Bootstrap Menu

When bootstrap is enabled the agent lands on a menu offering Pay by Phone (Keypad or Speech) and Pay by Link (Webchat, SMS or Email). The configuration controls which options appear and which is the default.

Pay by Link (Digital)

Pay by Link walkthrough

The agent sends the customer a secure capture link. The customer enters card details on their own device while the agent monitors progress in real time.

2. Configuration Overview and Options

Every Transact deployment stores one or more configurations as JSON documents against the account. The configuration name is passed in the launch URL via the configuration query parameter. If omitted, the account's default configuration is used.

A configuration is split into the following top-level sections:

Main
