Initiates an e-commerce transaction by sending a request to the Nayax Ecom SDK. This call is the beginning of a transaction and requests a payment page or prepares for a token-based charge. It supports various entry modes like ECOM, COF, or MOTO.
Authentication: The request requires a JWT RSA token in the header for authentication of both VAS integrator and VAS ECOM provider.
Timeout Recommendation: It is highly recommended to implement a timeout of 60 seconds on the client side. If no callback or response is received, retry the same /InitializeTransaction request. The EcomTransactionId is valid for 5 minutes from the /StartAuthentication response.
