# Make note of "jwt" from reply

This'll reply with JSON data, that includes a value for "jwt", to be used in other scripts that require you to be logged in.

Personally, I'd use the 'jq' program to de-serialize the JSON data, but I thought I'd keep the script simple for now

Awesome, thanks a bunch. I'm working through this now as I have minutes to spare, but the community id thing is returning "Query deserialize error: missing field q". I'm wondering if special characters and stuff are being parsed. I also replaced auth= in line 3 with jwt=, just FYI. Thanks, I'll keep plugging.

Ooops. I tested it before I posted, and the reason it worked is because it turns out that authentication isn't needed for that query.

I've edited the comment now, and there only being one part means that there's no need for an ampersand, so there's no probs with special characters.

That got me there. I just made my first scripted post. I'll take it from here with queuing my content. Thanks again!
