My wesbite developer uses ECWIDEcommerce Widget which is integrated into the website builder. The provided object does not work for them and they want to know if there are any other instructions they can follow to complete the SCA changes other than the ones provided.
If you’re using the official Ecwid integration, then Ecwid themselves will be the ones to update their plugin to implement SCA and you do not need to do anything on your end. To confirm on our end: as far as I know, Ecwid is in the process of enabling it and it should be good to go before the deadlines. Please let me know if you have additional questions or concerns!
