Automating Meeting Scheduling in an OpenClaw Sales Assistant

Introduction

Sales teams spend countless hours back‑and‑forth with prospects to lock down a time slot. When a sales assistant can automatically propose, confirm, and record a meeting, the pipeline moves faster and the human effort drops dramatically. This guide walks developers through extending the OpenClaw sales assistant with a fully automated meeting‑scheduling feature, using OpenClaw hosted on UBOS as the execution environment.

Overview of OpenClaw Sales Assistant

OpenClaw is a low‑code AI‑driven chatbot that can qualify leads, answer product questions, and hand off to human agents when needed. Built on the UBOS platform overview, it leverages Node‑RED for workflow orchestration, a web‑app editor for UI tweaks, and a library of AI integrations (e.g., OpenAI ChatGPT integration) to keep the conversation natural.

Prerequisites

• Access to an UBOS homepage account with permission to create Node‑RED flows.
• A calendar provider that offers a REST API (Google Calendar, Microsoft Graph, or Cal.com).
• API credentials (client ID/secret or token) stored securely in UBOS Workflow automation studio.
• Basic knowledge of JavaScript and Node‑RED function nodes.
• Optional: UBOS templates for quick start if you want a pre‑built UI.

Extending the Assistant to Add Meeting Scheduling

a. Setting Up Calendar Integration

First, register your application with the calendar provider and obtain OAuth 2.0 credentials. In UBOS, create a Secret Store entry (e.g., CALENDAR_TOKEN) and reference it in a Node‑RED http request node. The request must include the Authorization: Bearer <token> header.

b. Detecting Qualified Leads

OpenClaw already scores leads using a combination of intent detection and demographic checks. Add a function node that evaluates the leadScore field. When the score exceeds a configurable threshold (e.g., 80), the flow should branch to the scheduling sub‑flow.

c. Triggering Meeting Creation

The scheduling sub‑flow builds a JSON payload that matches the calendar API’s event schema. Key fields include summary, start, end, attendees, and conferenceData for video links. After the http request node returns a success response, send a confirmation message back to the prospect via OpenClaw’s chat node.

Step‑by‑Step Code Walkthrough

Node‑RED Flow Details

// Flow Overview (JSON export snippet)
[
  {
    "id":"lead_input",
    "type":"http in",
    "method":"post",
    "url":"/webhook/openclaw",
    "name":"OpenClaw webhook"
  },
  {
    "id":"lead_score",
    "type":"function",
    "name":"Score Check",
    "func":"if(msg.payload.leadScore >= 80){\n    return [msg, null];\n} else {\n    return [null, msg];\n}"
  },
  {
    "id":"schedule_meeting",
    "type":"subflow",
    "name":"Schedule Meeting Subflow"
  },
  {
    "id":"reply_success",
    "type":"http response",
    "name":"Reply to OpenClaw"
  }
]

Sample JavaScript Functions

Below are two reusable functions: one for building the calendar payload and another for formatting the confirmation text.

// buildEvent.js
function buildEvent({title, startTime, endTime, email}) {
  return {
    summary: title,
    start: {dateTime: startTime, timeZone: "UTC"},
    end:   {dateTime: endTime,   timeZone: "UTC"},
    attendees: [{email}],
    conferenceData: {
      createRequest: {requestId: "openclaw-" + Date.now()}
    }
  };
}

// formatConfirmation.js
function formatConfirmation(event) {
  return `✅ Your meeting “${event.summary}” is booked for ${new Date(event.start.dateTime).toLocaleString()}.
  Join via: ${event.conferenceData.entryPoints[0].uri}`;
}

Insert these functions into a function node inside the Schedule Meeting Subflow. The node should:

1. Extract prospect email and preferred time from msg.payload.
2. Call buildEvent() to create the payload.
3. Pass the payload to an http request node targeting https://www.googleapis.com/calendar/v3/calendars/primary/events?conferenceDataVersion=1.
4. On success, run formatConfirmation() and forward the text to the chat response node.

Best‑Practice Tips

Error Handling

• Wrap API calls in a try / catch block and route failures to a dedicated error sub‑flow.
• Detect common HTTP status codes (401, 403, 429) and implement exponential back‑off.
• Provide user‑friendly fallback messages, e.g., “I couldn’t book the meeting right now – please try again later.”

Security Considerations

• Never hard‑code tokens; use UBOS secret management (UBOS partner program guidelines).
• Validate incoming webhook payloads with a shared secret to prevent spoofing.
• Scope calendar permissions to https://www.googleapis.com/auth/calendar.events only.

Testing

Adopt a three‑layer testing strategy:

1. Unit tests for the JavaScript helpers using mocha or jest.
2. Integration tests that mock the calendar API with nock.
3. End‑to‑end tests using the UBOS Web app editor on UBOS to simulate a real user conversation.

Deployment on UBOS

Once the flow passes all tests, publish it to the Enterprise AI platform by UBOS. Follow these steps:

• Navigate to the Workflow automation studio and click “Import Flow”.
• Select the exported JSON file and confirm the secret bindings (calendar token, webhook secret).
• Enable the flow and set the schedule trigger to “always on”.
• Review the UBOS pricing plans to ensure you have enough compute credits for the expected traffic.

For startups, the UBOS for startups tier provides a generous free quota, while SMBs can benefit from the UBOS solutions for SMBs package.

Conclusion and Next Steps

Automating meeting scheduling transforms a reactive sales assistant into a proactive revenue engine. By leveraging OpenClaw’s lead‑scoring, Node‑RED’s visual orchestration, and UBOS’s secure deployment pipeline, developers can ship a production‑ready feature in a matter of hours.
