linkedin

Call the LinkedIn API with curl + jq. The user's bearer token is in $LINKEDIN_TOKEN; every call needs Authorization: Bearer $LINKEDIN_TOKEN.

LinkedIn posts must be authored by the member's URN. Get the member id from the OpenID userinfo endpoint, then build urn:li:person:{sub}.

SUB=$(curl -sS -H "Authorization: Bearer $LINKEDIN_TOKEN" \
  "https://api.linkedin.com/v2/userinfo" | jq -r .sub)
AUTHOR="urn:li:person:$SUB"
echo "$AUTHOR"

Errors are JSON with message / serviceErrorCode — show them verbatim. 401 → token expired (tokens last ~60 days), re-connect the LinkedIn connector.
