Cross-reference Fields
The system provides an ability to specify values that can be used for cross-referencing of entities between the gateway and a submitter’s system. The fields that can be provided by an integrated external system are listed below:
| Entity
|
Field Name
|
Description
|
| Ticket
|
ticketNumber*
|
Identifier of a ticket assigned by a POS system.
|
| ticketId*
|
Identifier of a ticket generated by a terminal.
|
| Item
|
itemNumber*
|
Identifier of a item assigned by a POS system.
|
| itemId*
|
Identifier of a item generated by a terminal.
|
*Fields ticketNumber/ticketId and itemNumber/itemId can be used subsequently as a reference in the operations designed to update tickets (close-ticket) and update items (update-item, remove-item).
Get Resource Response
The content of the response for get-resource operation is the content of the files that terminal attempts to download from the TMS. To help you with the download process, the following HTTP headers will be set:
- Status-Code, most common values: 200 – resource was found and content can be read or 404 – resource was not found;
- Content-Type - identifies the content type of the file being served;
- Content-Length - identifies the length of the file delivered.
Password Encoding
If passwords, as well as other fields, contain special characters (#, @, % etc.), the value of the fiels must be URL encoded.
For example, if the password is: 'Pa$$word', the URL encoded version of this password should be: Pa%24%24word.
For more information please read this article.
System Message
For cases when it is necessary to pass control information from a terminal to the TMS, systemMessage field is used.
Currently, the following values are supported:
- #initialized - terminal can pass this value to notify TMS that the terminal has been initialized.
- #ininjection – terminal can pass this value to notify TMS that the certificate has been signed.
- #provisioned - terminal can pass this value to notify TMS that the terminal is initialized and ready for activation by a merchant.
- #active - terminal can pass this value to notify TMS that the terminal has been registered and activated.
- #restart - terminal can pass this value to notify TMS that a registered terminal has performed an unplanned restart. The format of this message is the following: #restart(yyyyMMddHHmm,U), where yyyyMMddHHmm is a date and time of restart, and U indicates that restart was unplanned.
Note:
- hashtag symbol (#) should be passed as URL-encoded value, otherwise the operation will get failed. See integration notes for more information.
- such statuses as #initialized and #ininjection are used for Sunmi terminals only. The #provisioned status is used both for Sunmi and Ingeniko terminals.
TMS parameters
Terminal application behavior is controlled by a series of parameters, which are managed by the TMS. The terminal parameters get synchronized with the terminal both automatically and manually:
- automatic synchronization occurs on the regular basis (every hour) by calling get-configuration operation;
- manual synchronization occurs when the Parameters menu is opened on the terminal.
When the terminal is used, a user can review or manage the TMS parameters via the Parameters menu. Some parameters cannot be changed due to being set as read-only at the TMS level. Such parameters are sent to the terminal with @@ prefix included and cannot be modified at the terminal level.
To access the menu, manager PIN is required. In case if terminal services (such as get-credentials, get-time, get-parameters, get-update) are needed to access, administrator PIN is required.
See the following table to review a full list of the terminal parameters.
Terminal Code
When provisioning terminals in the portal, you have the ability to enter a 3-digit, numerical terminal code. This terminal code is passed in all API requests to identify the transaction’s target device. As such, it’s important that these terminal codes be tracked within your system. If you do not enter a terminal code, one will be assigned automatically. Each terminal will have a sticker which displays the terminal’s key, a numerical identifier which is comprised of the concatenated account code and terminal code. When a terminal arrives at its destination, the recipient should have the ability to register the device within your software, using the terminal code or key. We recommend that you enter the terminal in your database when you first provision it, making sure to include the terminal code and its related account code. This will allow you to associate the terminal with its recipient upon registration.
Terminal Hot Keys
Terminals of ICT, IPP, IWL, ISC Touch (Ingenico) and MX915, MX925 (VeriFone) models have special function buttons. They can be used to simplify an interaction with the terminal. You can use tables below as the reference to understand how the buttons are programmed in any of the terminal modes. Also, with these hot keys, you can quickly access a particular function that you need by pressing keys on the terminal keypad, as opposed to making selections within the terminal menus, which might be more time consuming.
Note: F1->[number] implies subsequent pressing of the key. For example, F1->7->1 means F1 is followed by 7, and 7 is followed by 1 on the terminal keypad.

Operations Frequency
Unlike other APIs, operations of the TMS API get executed mostly automatically. To learn how often and at what time automatic operations are run, see the table below. Note that the given time corresponds to the terminal time.
