HubSpot call tracking integration

Integrations / HubSpot

What you get

Every qualified call (passing your duration and screening rules) is delivered to HubSpot within about a minute: caller number, duration, timestamps, the campaign that generated the call, ad click IDs when present, and a recording link.

Step A — callstracking.com side

1. Create an account and set up your campaign (2 minutes).
2. Go to Dashboard → Integrations → Webhook / CRM.
3. Paste the webhook URL from HubSpot (Step B) and choose a signing secret.
4. Save. Qualified calls now POST to that URL automatically.

Step B — HubSpot side

1. In Zapier, create a Zap with trigger "Webhooks by Zapier → Catch Hook". Copy the hook URL.
2. Paste that URL into the callstracking.com webhook integration (Step A above) and save.
3. Make one qualified test call so Zapier captures a sample payload.
4. Add action "HubSpot → Find or Create Contact" matching on phone = fromE164.
5. Add action "HubSpot → Create Engagement (Call)" — set duration from durationSec, note from campaignName, and timestamp from startedAt.
6. Turn the Zap on.

The payload

Sent as JSON with content-type application/json. The recordingUrl opens in a signed-in callstracking.com session.

}

Verifying the signature

Every delivery is signed with your secret: header x-ct-signature: sha256=<hmac> over the raw body, plus x-ct-event: call.qualified. Platforms like Zapier and GoHighLevel can skip verification (the URL itself is secret); verify when posting to your own server:

// Node.js — verify the x-ct-signature header
import { createHmac } from "node:crypto";

const expected = "sha256=" +
  createHmac("sha256", process.env.CT_WEBHOOK_SECRET)
    .update(rawRequestBody)   // the exact raw body string
    .digest("hex");

const valid = expected === req.headers["x-ct-signature"];

Troubleshooting

• No delivery? Only qualified calls fire — check the call’s status on the Calls page (minimum duration, repeat-caller rules).
• Deliveries retry up to 5 times on non-2xx responses; the last error shows in the Calls page Conversions column.
• Changed the endpoint? Update the URL on the Integrations page — takes effect on the next call.
