Has anyone figured out a way to overwrite Data Extension rows via API call?
There isn't anything for it in documentation, neither SOAP API, SSJS, AMPscript, WSProxy or GTL seem to have an option to send data and overwrite everything in target Data Extension.
This boolean function seems to be supported only with SQL and File Import activities.
Anyway, to clear Data Extension via API call I would need to specify some unique ID's which isn't possible at the moment.
So currently I'm using API to send data to
DE1 which is then used by SQL query to pass it over (by overwriting) to
