Need a webhook "on delete" (newbie)

TLDR;
I want to propagate a object delete to an external DB, just like my creates and updates, using a webhook. How would I do that?

I use CC to post JA data to my MSSQL database.
Usually an Edit of a record, and sometimes an Add.

I have a table that nothing references… a child record if anything - safe to delete. If its deleted in JA (via DB.destroy), then it also needs to be deleted in MSSQL.
How do I trigger a CC task to delete in MSSQL?
(ie. There is no webhook for a Delete action)
