GMS: Release notes 22-06-2026

We released a few small improvements in our API's;

• The Terminals:Browse and Terminal:Get API now return for each terminal:
  • a terminalTypeCode e.g. TY-9050-9060 which refers to one of Pay's terminals types. See for a complete list of supported terminal types our Core data API; TerminalTypes
  • for each terminal in the settings a refund.mode with the possible values NONE, PER_TERMINAL, ALL. This field reflects the refund mode configured on the service to which the terminal is connected. The setting refund.allowed is deprecated as of now
• The Tokens:Browse endpoint is now showing the most recent created token on top.
• The object definition of the Service:GetConfig API in this documentation portal has changed for the settings object in the checkoutOptions array (full key: checkoutOptions.paymentMethods.settings). The API output already returned this as an object (i.e., a key/value pair for each setting), and the documentation has now been updated to reflect that output.
• We fixed a typo in the Service:EnablePaymentMethod/UpdatePaymentMethod API; we corrected the setting name dealWeroRSMEnabled
• We fixed an issue in the Statistics:Volume API; if the direction is 'CREDIT' the volume is a negative value instead of a positive value.
• We fixed an issue in the Transaction:Browse API; if the transaction was started in a different currency then EUR we now return in the amount object the amount and currency in which the transaction was started.
