# 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

Great. Now how would I make a post? Is there an API endpoint list somewhere?
I wanted to schedule my community posts, and tried to use this: https://github.com/RikudouSage/LemmySchedule but it doesn’t actually make posts for me. If I could use stuff like the above I could crontab it all out.
EDIT: Hmmm, looks like I found it https://join-lemmy.org/api/interfaces/CreatePost.html Now to test and figure it all out.
Hi. I’ve found the best place to test the api is here
Example script for making a post
my_instance="https://lemm.ee" auth="YOUR-JWT" community_id=COMMUNITY-ID name="TITLE OF POST" body="BODY OF POST" API="api/v3" create() { end_point="post" json_data="{\"auth\":\"$auth\",\"community_id\":$community_id,\"name\":\"$name\",\"body\":\"$body\"}" url="$my_instance/$API/$end_point" curl -H "Content-Type: application/json" -d "$json_data" "$url" } create
You’ll need to get your instance’s community.id for the community you want to post to. To use this community as an example, it would be:
my_instance="https://lemm.ee" API="api/v3" resolve() { end_point="resolve_object" www_data="q=https://lemmy.zip/c/linuxscripts" url="$my_instance/$API/$end_point?$www_data" curl "$url" } resolve(lemmy will probably sanitise the ampersand in that query, so you’ll have to replace the HTML with a literal ampersand)
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!
