No I’m not, but you could say I’m asking a side question to the original question. From what I can tell the current API doc (on the web) is not well defined in listing all the JSON parameters. For the slack one for instance, it doesn’t mention “url” field and expects you to know that, maybe from the slack API doc. So I was just questioning how one came to know that for this answer. For example, see this thread for how the OP figured it out: Slack enable image via curl
