How to Build a CRM Integration That Logs Every Sales Call Automatically

The problem with manual CRM logging

Sales reps spend an average of 20–30% of their time on administrative work — logging calls, writing notes, updating contact records. Most of it is data entry that a machine could do better and faster.

If your product is in the sales or RevOps space, automatically logging meeting data to a CRM is one of the highest-leverage features you can ship.

The architecture

Three components:

1. Gregnote — joins the meeting, transcribes, fires a webhook
2. Your server — receives the webhook, extracts structured data, calls the CRM API
3. Your CRM — HubSpot, Salesforce, Pipedrive, or any provider with a REST API

Step 1 — Send the bot to sales calls

Instrument your sales scheduling flow to send a bot whenever a call is booked:

// Called from your scheduling confirmation handler
async function attachBotToCall(meetingUrl, contactEmail, dealId) {
  await fetch("https://api.gregnote.com/v1/bots", {
    method: "POST",
    headers: { Authorization: `Bearer ${process.env.GREGNOTE_KEY}` },
    body: JSON.stringify({
      meeting_url: meetingUrl,
      bot_name: "Sales Notetaker",
      webhook_url: `https://api.yourproduct.com/hooks/call-ended`,
      metadata: { contact_email: contactEmail, deal_id: dealId },
    }),
  });
}

The metadata field passes context through to your webhook payload.

Step 2 — Parse the webhook and extract what matters

app.post("/hooks/call-ended", async (req, res) => {
  const { event, transcript, metadata } = JSON.parse(req.body);
  if (event !== "meeting.completed") return res.sendStatus(200);

const callSummary = { duration_minutes: Math.round(transcript.duration_seconds / 60), participants: transcript.speakers.filter(s => !s.is_bot).map(s => s.display_name), full_transcript: transcript.segments.map(s => ${s.speaker}: ${s.text}).join("\n"), deal_id: metadata.deal_id, contact_email: metadata.contact_email, };

await logToCRM(callSummary); res.sendStatus(200); }); ```

Step 3 — Log to HubSpot

async function logToCRM(call) {
  // Create a note on the contact
  await hubspot.crm.objects.notes.basicApi.create({
    properties: {
      hs_note_body: call.full_transcript,
      hs_timestamp: Date.now(),
    },
    associations: [{
      to: { id: call.contact_id },
      types: [{ associationCategory: "HUBSPOT_DEFINED", associationTypeId: 202 }],
    }],
  });
}

What you get

Every sales call your team takes now has a full transcript, duration, and participant list automatically attached to the right contact and deal record — the moment the meeting ends, with zero manual effort.
