openclaw skills install @byungkyu/linkedin-communityLinkedIn Community Management API integration with managed OAuth. Manage organization pages, posts, comments, reactions, and analytics. Use this skill when users want to create or manage LinkedIn posts, comment on posts, react to content, look up organizations, or retrieve follower/page/share statistics. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway). Requires network access and valid Maton API key. Calls run through the maton CLI with OAuth login; default to read and list calls, and confirm every write or new connection with the user.
openclaw skills install @byungkyu/linkedin-communityAccess the LinkedIn Community Management API with managed OAuth authentication. Manage organization pages, create and manage posts, comments, reactions, and retrieve analytics.
All access runs through the Maton gateway and the maton CLI.
maton login --oauth # authenticate once (OAuth, recommended)
maton connection create linkedin-community-management # connect the account (needs user approval)
maton api '/linkedin-community-management/rest/posts?author=...&q=author&count=10&start=0' -H 'Linkedin-Version: 202606' -H 'X-Restli-Protocol-Version: 2.0.0'
npm install -g @maton/cli
brew install maton-ai/cli/maton
maton login --oauth
Opens the OAuth login page in the browser and waits for authorization. Once complete, it creates a profile in config.toml (eg. $HOME/.config/maton/config.toml) and stores the access and refresh tokens in the operating system's credential store (Keychain on macOS, Credential Manager on Windows, Secret Service on Linux), auto-renewed on expiry. The CLI reads them when it needs them; nothing else should.
maton login --interactive
Requires manually copying an API key from Settings, which is error prone. Once complete, it also creates a profile in config.toml and stores the key in the same credential store. It is preferred over export MATON_API_KEY=..., which exposes a long-lived credential to every child process. When MATON_API_KEY is set, it overrides the active profile. If the CLI cannot be installed at all, see Appendix: Environments Without the CLI for the raw HTTP form and the rules for handling the key.

maton connection delete {connection_id} --yes
If there are multiple LinkedIn Community Management connections, specify which one to use so requests go to the intended account:
maton api '/linkedin-community-management/rest/posts?author=...&q=author&count=10&start=0' -H 'Linkedin-Version: 202606' -H 'X-Restli-Protocol-Version: 2.0.0'
LinkedIn Community Management has no typed maton linkedin-community-management commands yet, so every call goes through maton api.
maton api '/linkedin-community-management/rest/posts?author=...&q=author&count=10&start=0' -H 'Linkedin-Version: 202606' -H 'X-Restli-Protocol-Version: 2.0.0'
Paths are /linkedin-community-management/{native-api-path}. The gateway forwards everything after the app segment to api.linkedin.com/rest and injects the credential for the connection. Query strings, custom headers (except Host and Authorization), and all HTTP methods pass through. Send a JSON body with --input -:
maton api -X POST '/linkedin-community-management/{native-api-path}' -H 'Content-Type: application/json' --input - <<'JSON'
{"key": "value"}
JSON
Refer to maton api --help for possible flags and values.
Every LinkedIn call needs these headers, so pass them with -H:
| Header | Value | Description |
|---|---|---|
Linkedin-Version | YYYYMM (e.g. 202606) | API version |
X-Restli-Protocol-Version | 2.0.0 | Protocol version |
maton api '/linkedin-community-management/rest/me' -H 'Linkedin-Version: 202606' -H 'X-Restli-Protocol-Version: 2.0.0'
-H 'Linkedin-Version: 202606' \
-H 'X-Restli-Protocol-Version: 2.0.0'
The gateway proxies requests to api.linkedin.com/rest and automatically injects your OAuth token.
maton login --oauth, the token is held by the operating system's credential store and the CLI renews it on its own. Do not print it, write it to a file, pass it on a command line, or run maton token to look at one — only to hand it to a program that needs it.config.toml, or any other credential file — not for this skill, not for another application, and not to "check" that auth works (use maton whoami). Let the CLI use its own stored credential; the agent never needs the value. The same applies to unrelated secrets on the machine: .env files, SSH keys, cloud CLI credentials, and browser profiles are out of scope for an API gateway and must not be read or transmitted.api.maton.ai. Prefer endpoints that work with the gateway-injected connection credential.maton connection delete {connection_id}).maton connection create linkedin-community-management.

The two modes keep separate credential stores: the CLI uses the profile from maton login, while an SDK program signs in once with login(), which opens a browser and stores a session that Maton() reads. LinkedIn Community Management has no typed accessor yet, so calls go through the api passthrough, which takes the app and the path after it.

maton api '/linkedin-community-management/rest/posts?author=...&q=author&count=10&start=0'maton api '/rest/posts?author=...&q=author&count=10&start=0'A 500 may mean the LinkedIn Community Management authorization expired. With the user's approval, create a new connection (maton connection create linkedin-community-management) and complete authorization; once it is ACTIVE, delete the stale connection so the gateway uses the new one.
maton api.--paginate walks every page and -q/--jq trims the response before it reaches you. On typed commands, --jq requires --json.maton api; Host and Authorization are set by the gateway.Everything above uses the CLI, which holds the credential itself and never exposes it to the caller. Use the raw HTTP form below only where the CLI cannot be installed — a locked-down container, a CI step, a sandbox with no package manager. If maton is available, maton api does the same job without handling a secret.
Calling api.maton.ai directly means holding a long-lived Maton API key in the process environment, where it is readable by every child process and easy to leak into logs, crash dumps, shell history, and pasted output. Handle it accordingly:
[ -n "$MATON_API_KEY" ] && echo "MATON_API_KEY is set" || echo "MATON_API_KEY is not set"
.env, or a script makes it permanent. Let the environment that starts the session supply it — a CI secret store, a container secret, a secrets manager.ps output and shell history. Read it from the environment inside the process that makes the request, as below.api.maton.ai. It is not a credential for LinkedIn Community Management or any other third-party host.The request is a plain HTTPS call to host api.maton.ai at path /linkedin-community-management/{native-api-path} with a bearer token; the gateway swaps in the connected app's credential. Add a Maton-Connection: {connection_id} header to pin a specific connection when the account has more than one. Query values must be URL-encoded. The Python standard library is enough — the key is read from the environment inside the process, so it never appears on a command line:
python3 - <<'PY'
import json, os, urllib.request
GATEWAY = "https://api.maton.ai"
req = urllib.request.Request(GATEWAY + "/linkedin-community-management/rest/posts?author=...&q=author&count=10&start=0")
req.add_header("Authorization", "Bearer " + os.environ["MATON_API_KEY"])
req.add_header("User-Agent", "maton-linkedin-community-management-skill/1.2")
# req.add_header("Maton-Connection", "{connection_id}")
with urllib.request.urlopen(req) as resp:
print(json.dumps(json.load(resp), indent=2))
PY
For a write, set method="POST" (or PUT/DELETE) on the Request, pass the JSON-encoded body as data=, and add a Content-Type: application/json header.
The same rules as the CLI apply to every request made this way: read-only calls first, and explicit user confirmation before any POST, PUT, PATCH, or DELETE.
