Hi @rubenf , I came here in search of information about this. In my case, I'm trying to tell mailchimp about new members joining my app (like synchronizing contacts), but the webhook posted by my membership system can't be configured to use a bearer token. Does this mean windmill is essentially unable to handle this use case? Not a problem — I can just write it myself, but I was excited to have windmill at my disposal as a sort of "glue" system to tie my data together.
