# How to connect OneSignal REST API to OpenClaw (paste one key, 15 tools) > Connect OneSignal REST API to OpenClaw with ClawLink: paste your OneSignal REST API key once and 15 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/openclaw/onesignal-rest-api The usual route to OneSignal REST API access for OpenClaw is an MCP server you configure and keep running, plus your own OAuth app or API keys. ClawLink gives OpenClaw a more practical OneSignal REST API setup: install one ClawHub skill, connect OneSignal REST API in the browser, and OpenClaw can call real OneSignal REST API actions from any chat surface with no auth, token refresh, or tool wiring to build yourself. ## Setup It takes three steps to connect OpenClaw to OneSignal REST API. 1. **Install ClawLink** — add the plugin to OpenClaw once. 2. **Connect OneSignal REST API** — one-click OAuth in the ClawLink dashboard. 3. **Use it from chat** — ask OpenClaw in plain English. **Paste this into OpenClaw to set up ClawLink:** > I want to connect my apps to OpenClaw through ClawLink. > Please install the ClawLink plugin from ClawHub and enable it: `openclaw plugins install clawhub:clawlink-plugin` > When it is installed, tell me and stop. After I reply, give me the ClawLink pairing link. Setup notes, if you need them: https://claw-link.dev/skill.md **Alternative for any agent (no plugin needed):** if the OpenClaw plugin route isn't available or doesn't work, any AI agent with shell access can use the ClawLink CLI instead: ```bash npx -y @useclawlink/cli login # sign in via browser — no API key to paste npx -y @useclawlink/cli connect onesignal-rest-api # connect OneSignal REST API (browser OAuth) npx -y @useclawlink/cli actions onesignal-rest-api # list available actions npx -y @useclawlink/cli run onesignal-rest-api --input '' # execute (add --confirm for writes) ``` ### Install by command The setup prompt above does all of this in one paste. By hand, it is one install command plus a browser approval: ```bash openclaw plugins install clawhub:clawlink-plugin ``` Then ask OpenClaw to set up ClawLink. It starts browser pairing and prints an approval link — open it, approve the device, return to the chat, and say `done`. Finally, connect OneSignal REST API in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your OneSignal REST API API key once. Verify the connection by asking OpenClaw: > Pull the relevant data from OneSignal REST API, summarize it in plain English, and point out anything that needs attention. ### Using a different agent? The OpenClaw plugin is one client of ClawLink's MCP server. Claude Code, Cursor, Codex, or any agent that can run a shell command pairs with the same ClawLink account through the CLI: ```bash npx -y @useclawlink/cli login ``` `login` opens the same browser approval and stores a credential locally. Once OneSignal REST API is connected in the dashboard, that agent calls the same 15 OneSignal REST API tools over MCP.

ClawLink connects OneSignal REST API to OpenClaw and exposes 15 OneSignal REST API tools your agent can call over [MCP](https://claw-link.dev/learn/what-is-an-mcp-server), with [hosted auth](https://claw-link.dev/learn/oauth-for-ai-agents) and nothing to run or maintain yourself. Using Hermes instead? The [Hermes OneSignal REST API integration](https://claw-link.dev/hermes/onesignal-rest-api) works the same way. ## What the OpenClaw OneSignal REST API integration can do 15 OneSignal REST API tools are ready for OpenClaw once the account is connected. The 13 below are the ones people reach for most; your agent can call all 15. ### 13 of 15 OneSignal REST API tools for OpenClaw | Tool | What it does | |---|---| | **Fetch user identity** `onesignal_rest_api_fetch_user_identity` | Retrieve all aliases for a user identified by a specific alias | | **Get eligible iams** `onesignal_rest_api_get_eligible_iams` | Retrieve the manifest of In-App Messages that a subscription is eligible to display | | **View an app** `onesignal_rest_api_view_an_app` | Retrieve metadata for a single OneSignal app | | **View device** `onesignal_rest_api_view_device` | Retrieve details of a specific device (player) | | **View devices** `onesignal_rest_api_view_devices` | Retrieve a paginated list of devices (players) for a OneSignal app | | **View notifications** `onesignal_rest_api_view_notifications` | Retrieve details of multiple notifications | | **View segments** `onesignal_rest_api_view_segments` | View segments for a OneSignal app | | **Begin live activity** `onesignal_rest_api_begin_live_activity` | Start a Live Activity on OneSignal | | **Create notification** `onesignal_rest_api_create_notification` | Create and send a OneSignal push notification | | **Create template** `onesignal_rest_api_create_template` | Create reusable message templates for push, email, and SMS channels | | **Create user** `onesignal_rest_api_create_user` | Create a OneSignal user with optional subscriptions and aliases | | **Update device** `onesignal_rest_api_update_device` | Update properties of an existing device | | **Update subscription** `onesignal_rest_api_update_subscription` | Update an existing subscription's properties | ## Example prompts **Fetch User Identity** > Pull the relevant data from OneSignal REST API, summarize it in plain English, and point out anything that needs attention. **Get Eligible Iams** > Pull the relevant data from OneSignal REST API, summarize it in plain English, and point out anything that needs attention. **View An App** > Use OneSignal REST API to view an app and walk me through the result in plain English. **View Device** > Use OneSignal REST API to view device and walk me through the result in plain English. ## ClawLink vs. building it yourself The alternative to ClawLink is usually manual API key setup plus your own token handling, permission troubleshooting, and tool plumbing for OpenClaw. That is fine if you want to build and maintain the integration yourself. Most teams just want OneSignal REST API working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the OneSignal REST API API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected OneSignal REST API account becomes available to the agent without you building credential management. | | **Ongoing maintenance** | You own refresh logic, permission debugging, environment config, and every provider-specific edge case for OneSignal REST API. | ClawLink handles the repetitive integration plumbing so your team can focus on the workflow instead of the infrastructure. | | **Agent usability** | You still need to expose the right OneSignal REST API actions to the runtime in a format your agent can reliably use. | 15 tools for OneSignal REST API are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes OneSignal REST API to AI agents. It is developer infrastructure: Python and TypeScript SDKs, an MCP server, and a catalog past 1,000 apps, aimed at teams shipping agent products. ClawLink is built for OpenClaw users instead. You install the plugin once, connect OneSignal REST API in the browser, and the 15 tools above work from chat. There is no SDK and no config file, and the OneSignal REST API key you paste at setup is stored server-side rather than kept in your environment. Choosing between them? Read the full [Composio alternatives](https://claw-link.dev/hub/composio-alternatives) comparison. ### OpenClaw installed the OneSignal REST API skill but can't call the tools The ClawHub skill teaches OpenClaw about OneSignal REST API, but the calls run through the ClawLink plugin and your connected account. Make sure OneSignal REST API is connected in the dashboard, then start a fresh chat so OpenClaw reloads the tool catalog. If OpenClaw runs as a persistent gateway, restart it so the new tools register. ### Connection succeeds but no tools appear Reconnect OneSignal REST API from the dashboard, then start a fresh chat if the runtime still has the old tool catalog loaded. ### "Tool schema not loaded yet" error when calling OneSignal REST API tools OneSignal REST API tool schemas load on demand the first time a tool runs and are cached after that, so this error usually clears on its own: wait a few seconds and retry the same request. If every OneSignal REST API call keeps failing with it in a fresh chat, reconnect from the dashboard, and contact support if it still persists — that pattern points to a configuration problem on our side, not something you can fix by reconnecting again. ### OneSignal REST API returns 403 or "permission denied" on one action while others work Two usual causes. The connected account may not have access to the specific workspace, inbox, store, or project in the request — check that first. If access looks right, the agent may have sent a placeholder value (like "YOUR_ID" or an example id from documentation) instead of a real one: ask it to run a list or search tool first, then retry the action with a real id from those results. Most failures at this stage are one of these two, not ClawLink bugs. ### API key setup works but results look incomplete Double-check that the API key for OneSignal REST API has the right scopes or account access. A valid key can still be too limited for some reads or writes. ### Is there a OpenClaw OneSignal REST API integration? Yes. ClawLink is the fastest way to connect OpenClaw to OneSignal REST API: link your OneSignal REST API account once in the browser and OpenClaw can call the OneSignal REST API API through 15 ready-made tools — no custom code or token handling. ### How do I add OneSignal REST API to OpenClaw with ClawLink? Paste the setup prompt from this page into OpenClaw. It installs the ClawLink OneSignal REST API skill from ClawHub, then you click Connect in the dashboard to authorize OneSignal REST API. OpenClaw calls the tools from the next message — no config files, and the OneSignal REST API key you paste is stored server-side instead of in your environment. ### How long does it take to connect OneSignal REST API to OpenClaw? About two minutes. Sign in, click Connect next to OneSignal REST API in the dashboard, authenticate, and OpenClaw can use it from the next chat message. ### Why use ClawLink instead of wiring OneSignal REST API up myself? The alternative to ClawLink is usually manual API key setup plus your own token handling, permission troubleshooting, and tool plumbing for OpenClaw. That is fine if you want to build and maintain the integration yourself. Most teams just want OneSignal REST API working from chat. ### OpenClaw installed the OneSignal REST API skill but can't call the tools The ClawHub skill teaches OpenClaw about OneSignal REST API, but the calls run through the ClawLink plugin and your connected account. Make sure OneSignal REST API is connected in the dashboard, then start a fresh chat so OpenClaw reloads the tool catalog. If OpenClaw runs as a persistent gateway, restart it so the new tools register. ## Related - [OpenClaw SendGrid integration](https://claw-link.dev/openclaw/sendgrid) — Deliver transactional and marketing emails - [OpenClaw Dialpad integration](https://claw-link.dev/openclaw/dialpad) — Business phone, messaging, and video conferencing - [Connect Discord Bot](https://claw-link.dev/openclaw/discord-bot) — Automate Discord server actions with bot-specific permissions
