# How to connect Square to OpenClaw (no API keys) > Connect Square to OpenClaw with ClawLink in one click — 122 tools your AI agent can call from chat via hosted OAuth. No API keys, no manual setup. Web version: https://claw-link.dev/openclaw/square The usual route to Square 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 Square setup: install one ClawHub skill, connect Square in the browser, and OpenClaw can call real Square actions from any chat surface with no auth, token refresh, or tool wiring to build yourself. **Start here:** install the ClawLink plugin (`openclaw plugins install clawhub:clawlink-plugin`), pair it in the browser, then connect the app in the ClawLink dashboard. The interactive install prompt is on the web version of this page: https://claw-link.dev/openclaw/square ## Setup It takes three steps to connect OpenClaw to Square. 1. **Install ClawLink** — add the plugin to OpenClaw once. 2. **Connect Square** — one-click OAuth in the ClawLink dashboard. 3. **Use it from chat** — ask OpenClaw in plain English. **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 square # connect Square (browser OAuth) npx -y @useclawlink/cli actions square # list available actions npx -y @useclawlink/cli run square --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 Square in the [ClawLink dashboard](https://claw-link.dev/dashboard) — a one-click OAuth approval, no API keys. Verify the connection by asking OpenClaw: > Create it in Square for me, then confirm the important fields before you finish. ### 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 Square is connected in the dashboard, that agent calls the same 122 Square tools over MCP.

ClawLink connects Square to OpenClaw and exposes 122 Square 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 Square integration](https://claw-link.dev/hermes/square) works the same way. ## What the OpenClaw Square integration can do 122 Square tools are ready for OpenClaw once the account is connected. The 30 below are the ones people reach for most; your agent can call all 122. ### 30 of 122 Square tools for OpenClaw | Tool | What it does | |---|---| | **Create customer** `square_create_customer` | Create a new customer profile in Square. | | **Create order** `square_create_order` | Create a new order in Square. | | **List customers** `square_list_customers` | List customer profiles in Square. | | **List invoices** `square_list_invoices` | List Square invoices. | | **List locations** `square_list_locations` | List business locations in Square. | | **List payments** `square_list_payments` | List payments in Square. | | **List subscriptions** `square_list_subscriptions` | List Square subscriptions. | | **Retrieve customer** `square_retrieve_customer` | Get a Square customer by ID. | | **Retrieve order** `square_retrieve_order` | Get a Square order by ID. | | **Search catalog objects** `square_search_catalog_objects` | Search catalog objects in Square. | | **Update customer** `square_update_customer` | Update an existing Square customer. | | **Calculate order** `square_calculate_order` | Preview order pricing without creating an order | | **Get booking** `square_get_booking` | Retrieves detailed information about a specific Square booking by its ID | | **Get business booking profile** `square_get_business_booking_profile` | Retrieve the business booking profile for a Square merchant via GraphQL | | **Get current merchant** `square_get_current_merchant` | Retrieve merchant information associated with the access token using Square's GraphQL API | | **Get customer custom attribute** `square_get_customer_custom_attribute` | Retrieves a custom attribute from a customer profile in Square | | **Get customers custom attribute definitions** `square_get_customers_custom_attribute_definitions` | Retrieve a customer-related custom attribute definition from Square | | **Get customers graphql** `square_get_customers_graphql` | Retrieve customer profiles from Square Customer Directory using GraphQL API | | **Get dispute evidence** `square_get_dispute_evidence` | Retrieves detailed information about a specific piece of evidence that was uploaded for a | | **Get gift card from gan** `square_get_gift_card_from_gan` | Retrieves detailed information about a gift card by its GAN (gift card account number) | | **Get invoice** `square_get_invoice` | Retrieves detailed information about a specific Square invoice by its ID | | **Get loyalty account** `square_get_loyalty_account` | Retrieve detailed information about a specific Square loyalty account by ID | | **Get merchant** `square_get_merchant` | Retrieve detailed information about a specific Square merchant by ID | | **Get online checkout location settings** `square_get_online_checkout_location_settings` | Retrieve location-level settings for Square online checkout | | **Get refund** `square_get_refund` | Retrieves a specific payment refund by its unique ID from Square | | **Get subscription** `square_get_subscription` | Retrieves detailed information about a specific Square customer subscription by its ID | | **Get team member** `square_get_team_member` | Retrieve detailed information about a specific Square team member by ID | | **List cards** `square_list_cards` | Retrieve cards on file associated with a Square account | | **List channels** `square_list_channels` | List requested channels from Square | | **List customer custom attribute definitions** `square_list_customer_custom_attribute_definitions` | List customer-related custom attribute definitions from Square | ## Example prompts **Create Customer** > Create it in Square for me, then confirm the important fields before you finish. **Create Order** > Create it in Square for me, then confirm the important fields before you finish. **List Customers** > List the relevant items in Square, group them by priority, and recommend what OpenClaw should do next. **List Invoices** > List the relevant items in Square, group them by priority, and recommend what OpenClaw should do next. ## ClawLink vs. building it yourself The alternative to ClawLink is usually manual OAuth app 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 Square working from chat. | | Manual | ClawLink | |---|---|---| | **Connection flow** | Register a Square app, configure redirect URLs, manage consent details, and reconnect users when auth settings drift. | Users connect Square through the hosted browser flow and ClawLink keeps the token lifecycle out of your app code. | | **Ongoing maintenance** | You own refresh logic, permission debugging, environment config, and every provider-specific edge case for Square. | 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 Square actions to the runtime in a format your agent can reliably use. | 122 tools for Square are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Square 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 Square in the browser, and the 122 tools above work from chat. There is no SDK, no config file, and no API key handling. Choosing between them?

Make sure Square 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 Square 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 Square tools Square 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 Square 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. ### Square 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. ### OAuth finished in the browser but the account is still missing Try reconnecting Square and complete the consent flow in the same browser session. Partial OAuth approvals or switching accounts mid-flow can leave the connection incomplete. ### Is there a OpenClaw Square integration? Yes. ClawLink is the fastest way to connect OpenClaw to Square: link your Square account once in the browser and OpenClaw can call the Square API through 122 ready-made tools — no custom code or token handling. ### How do I add Square to OpenClaw with ClawLink? Paste the setup prompt from this page into OpenClaw. It installs the ClawLink Square skill from ClawHub, then you click Connect in the dashboard to authorize Square. OpenClaw calls the tools from the next message — no config files or API keys to manage. ### How long does it take to connect Square to OpenClaw? About two minutes. Sign in, click Connect next to Square in the dashboard, authenticate, and OpenClaw can use it from the next chat message. ### Why use ClawLink instead of wiring Square up myself? The alternative to ClawLink is usually manual OAuth app 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 Square working from chat. ### OpenClaw installed the Square skill but can't call the tools The ClawHub skill teaches OpenClaw about Square, but the calls run through the ClawLink plugin and your connected account.
