To perform advanced actions that may not be available through the E-commerce+ interface in the Editor, you can make use of the Ecwid API.
Ecwid API tokens can be accessed with a simple call to the Mono HAL API:
curl --location --request POST 'https://hal.mono.net/api/v1/reseller/account/site' \
--header 'Content-Type: application/json' \
--data-raw '{
"command": "getEcwidAccessToken",
"siteId": "siteId",
"userToken": "HAL_token"
}'
