# How to connect PostGrid Verify to OpenClaw (paste one key, 12 tools)

> Connect PostGrid Verify to OpenClaw with ClawLink: paste your PostGrid Verify key once and 12 tools work from chat. No MCP server to run, nothing stored on your machine.

Web version: https://claw-link.dev/openclaw/postgrid-verify

The usual route to PostGrid Verify 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 PostGrid Verify setup: install one ClawHub skill, connect PostGrid Verify in the browser, and OpenClaw can call real PostGrid Verify 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 PostGrid Verify.

1. **Install ClawLink** — add the plugin to OpenClaw once.
2. **Connect PostGrid Verify** — 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 postgrid-verify  # connect PostGrid Verify (browser OAuth)
npx -y @useclawlink/cli actions postgrid-verify  # list available actions
npx -y @useclawlink/cli run postgrid-verify <action> --input '<json>'  # 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 PostGrid Verify in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your PostGrid Verify API key once.

Verify the connection by asking OpenClaw:

> Use PostGrid Verify to autocomplete address and walk me through the result in plain English.

### 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 PostGrid Verify is connected in the dashboard, that agent calls the same 12 PostGrid Verify tools over MCP.

## PostGrid Verify MCP for OpenClaw

Looking for a PostGrid Verify MCP server for OpenClaw? ClawLink connects PostGrid Verify to OpenClaw and exposes 12 PostGrid Verify 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 PostGrid Verify integration](https://claw-link.dev/hermes/postgrid-verify) works the same way.

## What the OpenClaw PostGrid Verify integration can do

12 PostGrid Verify tools are ready for OpenClaw once the account is connected.

## 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 PostGrid Verify working from chat.

| | Manual | ClawLink |
|---|---|---|
| **Credential handling** | Collect, validate, store, and rotate the PostGrid Verify API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected PostGrid Verify 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 PostGrid Verify. | 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 PostGrid Verify actions to the runtime in a format your agent can reliably use. | 12 tools for PostGrid Verify are already exposed through ClawLink, so the agent can read and act from chat immediately. |

## ClawLink vs. Composio

Composio also exposes PostGrid Verify 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 PostGrid Verify in the browser, and the 12 tools above work from chat. There is no SDK and no config file, and the PostGrid Verify key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

### OpenClaw installed the PostGrid Verify skill but can't call the tools
The ClawHub skill teaches OpenClaw about PostGrid Verify, but the calls run through the ClawLink plugin and your connected account. Make sure PostGrid Verify 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 PostGrid Verify 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 PostGrid Verify tools
PostGrid Verify 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 PostGrid Verify 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.

### PostGrid Verify 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 PostGrid Verify has the right scopes or account access. A valid key can still be too limited for some reads or writes.

### Is there a OpenClaw PostGrid Verify integration?
Yes. ClawLink is the fastest way to connect OpenClaw to PostGrid Verify: link your PostGrid Verify account once in the browser and OpenClaw can call the PostGrid Verify API through 12 ready-made tools — no custom code or token handling.

### How do I add PostGrid Verify to OpenClaw with ClawLink?
Paste the setup prompt from this page into OpenClaw. It installs the ClawLink PostGrid Verify skill from ClawHub, then you click Connect in the dashboard to authorize PostGrid Verify. OpenClaw calls the tools from the next message — no config files, and the PostGrid Verify key you paste is stored server-side instead of in your environment.

### How long does it take to connect PostGrid Verify to OpenClaw?
About two minutes. Sign in, click Connect next to PostGrid Verify in the dashboard, authenticate, and OpenClaw can use it from the next chat message.

### Why use ClawLink instead of wiring PostGrid Verify 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 PostGrid Verify working from chat.

### OpenClaw installed the PostGrid Verify skill but can't call the tools
The ClawHub skill teaches OpenClaw about PostGrid Verify, but the calls run through the ClawLink plugin and your connected account. Make sure PostGrid Verify 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.
