New acceptor_terminal_id Available in Transaction
Release date: April 17, 2025
Impact: New acceptor_terminal_id in the transaction object
Audience: All customers
Action required: None
Products affected: Card Transactions

Overview

We are introducing a acceptor_terminal_id to the pos.terminal object within the transaction object. This field was previously made available in the Authorization Steam Access (ASA) request.

The Acceptor Terminal ID value uniquely identifies a terminal at the card acceptor location of acquiring institutions or merchant POS systems.

Impact

The transaction object is returned by the:

• Get Card Transaction endpoint,
• List Card Transactions endpoint, and
• Event webhooks of type card_transaction.updated

Customers using any of the above will observe a new pos.terminal.acceptor_terminal_id field.

Note: This change is purely additive and will not affect existing integrations.
