# How to connect ClickSend to Hermes Agent (paste one key, 166 tools)

> Connect ClickSend to Hermes with ClawLink: paste your ClickSend key once and 166 tools work from chat. No MCP server to run, nothing stored on your machine.

Most guides for giving Hermes Agent ClickSend access start with registering your own OAuth app or pasting API keys into env files, then leave the token refresh and tool wiring to you. ClawLink gives Hermes a more practical ClickSend setup: pair once in the browser and your always-on Hermes agent can act on ClickSend for you, reading and doing real work on your behalf with no auth, token refresh, or tool wiring to build yourself.

## Setup

It takes three steps to connect Hermes to ClickSend.

1. **Install ClawLink** — add the plugin to Hermes Agent once.
2. **Connect ClickSend** — one-click OAuth in the ClawLink dashboard.
3. **Use it from chat** — ask Hermes Agent in plain English.

**Paste this into Hermes to set up ClawLink:**

> Set up ClawLink for Hermes and tell me when it's ready.
> 1. Install the plugin: `hermes plugins install ClawLink-HQ/hermes-plugin --enable`
> 2. Start pairing with `hermes clawlink begin`. It prints an approval link, so show me the link and stop, don't wait.
> 3. I'll approve it in my browser, then reply "approved".
> 4. When I say approved, finish setup: `hermes clawlink finish`
> 5. Then run `hermes clawlink test` and tell me whether ClawLink is ready.

**Alternative for any agent (no plugin needed):** if the Hermes Agent 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 clicksend  # connect ClickSend (browser OAuth)
npx -y @useclawlink/cli actions clicksend  # list available actions
npx -y @useclawlink/cli run clicksend <action> --input '<json>'  # execute (add --confirm for writes)
```

### Install by command

The prompt above walks Hermes through this. By hand, it is four commands and a browser approval:

```bash
hermes plugins install ClawLink-HQ/hermes-plugin --enable
hermes clawlink begin    # prints an approval link — open it and approve
hermes clawlink finish   # after approving in the browser
hermes clawlink test
```

Then connect ClickSend in the [ClawLink dashboard](https://claw-link.dev/dashboard) — enter your ClickSend account details once.

Verify the connection by asking Hermes:

> Use ClickSend to account useage by subaccount get and walk me through the result in plain English.

### Using a different agent?

The Hermes 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 ClickSend is connected in the dashboard, that agent calls the same 166 ClickSend tools over MCP.

## ClickSend MCP for Hermes

Looking for a ClickSend MCP server for Hermes Agent? ClawLink connects ClickSend to Hermes Agent and exposes 166 ClickSend 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 OpenClaw instead? The [OpenClaw ClickSend integration](https://claw-link.dev/openclaw/clicksend) works the same way.

## What the Hermes Agent ClickSend integration can do

## ClawLink vs. building it yourself

The alternative to ClawLink is usually manual credential setup plus your own token handling, permission troubleshooting, and tool plumbing for Hermes Agent. That is fine if you want to build and maintain the integration yourself. Most teams just want ClickSend working from chat.

| | Manual | ClawLink |
|---|---|---|
| **Setup flow** | Collect and store the right ClickSend credentials yourself, then keep the account mapping and request format correct. | ClawLink keeps the setup in one hosted flow so non-technical users can link ClickSend without custom integration screens. |
| **Ongoing maintenance** | You own refresh logic, permission debugging, environment config, and every provider-specific edge case for ClickSend. | 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 ClickSend actions to the runtime in a format your agent can reliably use. | 166 tools for ClickSend are already exposed through ClawLink, so the agent can read and act from chat immediately. |

## ClawLink vs. Composio

Composio also exposes ClickSend 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 Hermes Agent users instead. You install the plugin once, connect ClickSend in the browser, and the 166 tools above work from chat. There is no SDK and no config file, and the ClickSend 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.

### Hermes paired but still can't use ClickSend
Pairing is a two-step handshake: run `hermes clawlink begin`, approve the link in your browser, then run `hermes clawlink finish`. If you ran finish before approving, or the approval link expired, run `hermes clawlink begin` again to get a fresh link. Confirm the plugin was installed with `--enable`, then verify with `hermes clawlink test`.

### Connection succeeds but no tools appear
Reconnect ClickSend 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 ClickSend tools
ClickSend 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 ClickSend 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.

### ClickSend 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.

### The setup form accepts credentials but calls still fail
Re-enter the credentials carefully and verify the account-level permissions for ClickSend. Basic and token-based integrations tend to fail on formatting mistakes or limited account roles.

### Is there a Hermes Agent ClickSend integration?
Yes. ClawLink is the fastest way to connect Hermes to ClickSend: link your ClickSend account once in the browser and Hermes Agent can call the ClickSend API through 166 ready-made tools — no custom code or token handling.

### How do I connect ClickSend to Hermes with ClawLink?
Install the plugin with `hermes plugins install ClawLink-HQ/hermes-plugin --enable`, then pair once: run `hermes clawlink begin`, approve the link in your browser, and run `hermes clawlink finish`. Connect ClickSend in the dashboard and Hermes can use it from the next message — no config files, and the ClickSend key you paste is stored server-side instead of in your environment.

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

### Why use ClawLink instead of wiring ClickSend up myself?
The alternative to ClawLink is usually manual credential setup plus your own token handling, permission troubleshooting, and tool plumbing for Hermes Agent. That is fine if you want to build and maintain the integration yourself. Most teams just want ClickSend working from chat.

### Hermes paired but still can't use ClickSend
Pairing is a two-step handshake: run `hermes clawlink begin`, approve the link in your browser, then run `hermes clawlink finish`. If you ran finish before approving, or the approval link expired, run `hermes clawlink begin` again to get a fresh link. Confirm the plugin was installed with `--enable`, then verify with `hermes clawlink test`.
