# Start EFT Payment (Cloud)

POST https://api.npretail.app/{tenant}/{environment}/{company}/pos/sale/{saleId}/eft/{transactionId}/cloud/start

Starts the EFT payment by sending the request to the Adyen cloud terminal API synchronously.
This call blocks until the terminal responds (up to 5 minutes on BC SaaS).
The response indicates whether the request was processed - poll the status endpoint to get the actual payment result.
