Poll - Terminal Config Response

Check via the poll method if the terminal has responded to a merchant configuration request.

This method is rate limited to 1 request per 500ms per pollId.

Nota

  • 404 does not mean failure: A 404 Not Found response means the terminal has not yet returned a merchant configuration. This is normal and expected — you should continue polling. Only stop polling when you receive a 200 OK (response available) or 408 Request Timeout (response expired).

  • Responses have a TTL: If you do not poll within the timeout window, the response expires. You will need to send a new /poll/requestMerchantConfig request to try again.

  • Merchant configuration requests do not trigger a SALE_RECEIVEDevent. The terminal immediately processes the request and returns the list of merchants via a MERCHANT_CONFIG callback.
