threads

Call the Threads API (graph.threads.net) with curl + jq. The connector injects one credential: $THREADS_ACCESS_TOKEN (a long-lived Threads access token with the threads_basic + threads_content_publish scopes). Never echo it.

Resolve the caller's Threads user id once (every publish needs it):

ME=$(curl -sS "https://graph.threads.net/v1.0/me?fields=id,username&access_token=$THREADS_ACCESS_TOKEN")
TID=$(echo "$ME" | jq -r .id)
echo "$ME"     # {"id":"<THREADS_USER_ID>","username":"..."}

Errors are JSON with error.message / error.code — show them verbatim. 401 / OAuthException → the token expired or lacks scope; reconnect the Threads connector.
