How use HTTP integration?

I’m trying to find the easiest way of removing the “?event=up” suffix that is hard-coded into the HTTP integration. So far I’m thinking the only way is to pipe the output into Sed to strip that off, then curl to send to my endpoint? (It’s an external service I can’t control their handling of URLs and the suffix freaked their server out) At the moment I’m wanting to send decoded data. I’m just having to come back into this arena so am learning as I go. Any pointers would be valuable!

Solved using Python with API libraries as mentioned in the docs, used the ‘requests’ library to forward packets on. Nice and easy.
