Poll - Request Merchant Config
Send a request using the poll method to discover available multi-tenant merchant profiles configured on a PAX POS device.
This endpoint allows you to retrieve merchant configuration information from a payment device using polling. The terminal will respond with available merchants, currencies, and terminal details.
Flow:
Send request to terminal with pollId.
Terminal processes request.
Poll the /poll/terminalConfigResponse/{pollId} endpoint to retrieve the response.
Response: Use the returned pollId to poll the terminalConfigResponse endpoint until the response is available. The response will contain eventType "MERCHANT_CONFIG" with merchant configuration details.
Rate Limiting: The polling endpoint is rate-limited to one call per second per pollId.
Nota
Merchant configuration requests do not trigger a SALE_RECEIVED event. The terminal immediately processes the request. To retrieve the result, you must poll the /poll/terminalConfigResponse/{pollId} endpoint, NOT the standard terminal response endpoint.
pollId
The ID used to poll after a terminal response.
deviceToken
The token of a PAX POS device.
correlationId
An ID provided by the caller. Will be returned in the callback for message matching.
timeToLive
The maximum time, in seconds, for a request to reach the physical terminal. The default value is 5 seconds.
terminalId
If terminal has more than one merchant, this field is used to identify the merchant. To get a list of merchants, use the requestMerchantConfig request. Value can be null.
