Hi Yvann,
If we talk about the object "Utility - Interact API" which calls actions from "Interact Web API Service", the current Interact version 4.1 does not seem to offer "Delete Submission" by submission ID. Instead, it offers "Move Submission to Archived", which I personally prefer as generic approach (archive rather than delete). You may know that, from the Interact, Submission History, a user can also "Mass archive" his/her submissions.
Having understood the requirement here, you might want to share your idea
here for future product improvements.
Regards, Kana
