The TIM API is the standard application interface for ECR integration using SIX Payment Services terminals.

TIM API provides a comprehensive feature set to support the requirements of several different markets. This guideline is intended to be used by ECR integrators that need to implement the TIM API functionality in their products.

The following document contains an overview structure and describes the corresponding functions, notifiers and data elements that can be used with the TIM API. Furthermore implementation examples are provided. Nevertheless always the corresponding description of a function or data element is authoritative, not the examples.

The TIM API is available for multiple platforms. Due to such diversity the support for the TIM API is limited to certain standards. Those are the minimal system requirements:

Once a Terminal-instance has been created with a TerminalSettings-instance, the settings can not be changed anymore. Changes to the TerminalSettings-instance will be ignored.

The network and guides configuration are explained in the following chapters. For further information refer toTerminalSettings.

Follow these basic steps for using the TIM API:

1. Create TerminalSettings and initialize connection parameters (see Setup Configuration)
2. Create Terminal instance using the created TerminalSettings
3. Set some properties where required:
   • Define a POS ID
   • create mandatory list of EcrInfo and add with addEcrData
   • create list of PrintOptions and set with setPrintOptions
   • addListeners
4. Connect and Login. This can be done automatically, when the first terminal operation is called or manually using the login method.
5. Use terminal operation functions.

The TIM API uses two different types of automatisms:

• Pre-Automatisms: This means that all actions that need to be done before a function can be called. E.g. a transaction can be called in disconnected state without having called connect, login and activate in advance. These are called automatically by the TIM API before the transaction is performed. The Pre-Automatisms are enabled by default.

• Post-Automatisms: These automatisms can be enabled or disabled using the members autoCommit and fetchBrands. A Post-Automatism is triggered after an action has been performed. E.g. if a connect has been called and fetchBrands is activated, an applicationInformation request is called automatically after the connect. Or if autoCommit is activated a commit is performed automatically after a transaction has been made. AutoCommit and fetchBrands are enabled by default.

The following diagram shows the principle of the Pre-Automatisms and Post-Automatisms. Pre-Automatisms are enabled by default and cannot be disabled. If an error occurs the started request from the ECR is returned with an error.

This chapter describes various guides and their use cases.

All terminal methods are in async-mode. Method-calls return immediately after the operation has started or throws a TimException otherwise. A listener-event-method will be called after operation is finished successfully. All listener-event-methods contain a TimEvent. In case of failure a ResultCode is included. User-implemented listener-handlers (that extend DefaultTerminalListener) can be added to the Terminal-instance with addListener.

Code example for adding a terminal listener:

/** Asynchronous listener handling terminal events. */

/* Define your own TerminalListener by overwrite all required 
 * methods from the DefaultTerminalListener class
 * which you want to use.
*/
class MyTerminalListener extends timapi.DefaultTerminalListener {

// Overwrite all wanted methods of the DefaultTerminalListener herein

}

/* Then create an instance of your "MyTerminalListener" and add it to
 * your terminal instance.
*/
var myListener = new MyTerminalListener();

terminal.addListener(myListener);
