Connect Capsule CRM to IntelDialix voice agents

Store clean caller history, recording URLs, and next steps inside Capsule relationship records.

In short

You connect Capsule CRM to IntelDialix in two directions. When a call starts or ends, IntelDialix sends a signed webhook to Capsule CRM with the transcript and outcome. During a call, an agent can reach Capsule CRM through a custom tool — an HTTP request you define — to look up or update information. No SDK is needed; it is plain HTTPS and JSON.

How it works

How information moves between a live phone call and Capsule CRM.

  1. 01

    A call reaches your agent

    A caller dials a Twilio or SIP number assigned to the agent, or the agent places an outbound call from a campaign.

    Twilio / SIP number → IntelDialix agent

  2. 02

    The agent uses Capsule CRM mid-call

    When the conversation needs data, the agent runs a custom tool: an HTTP request to Capsule CRM with the details it has collected.

    Custom tool → Capsule v2 REST API

  3. 03

    The call ends with a record

    IntelDialix keeps the recording, transcript and post-call analysis for the conversation in your call history.

    Recording · transcript · analysis

  4. 04

    Capsule CRM receives the result

    A signed webhook delivers the call event to your Capsule CRM endpoint, and is retried automatically if the delivery fails.

Example

verify-dialix-webhook.js
// Verify an IntelDialix webhook before trusting it in Capsule CRM.
// Header: X-Dialix-Signature: t=<unix seconds>,v1=<hex>
// where v1 = HMAC-SHA256(secret, "<t>.<raw request body>")
import crypto from 'node:crypto';

export function verifyDialixWebhook(rawBody, signatureHeader, secret) {
  const parts = Object.fromEntries(
    signatureHeader.split(',').map((kv) => kv.split('='))
  );
  const expected = crypto
    .createHmac('sha256', secret)
    .update(`${parts.t}.${rawBody}`)
    .digest('hex');
  const valid =
    typeof parts.v1 === 'string' &&
    parts.v1.length === expected.length &&
    crypto.timingSafeEqual(Buffer.from(parts.v1), Buffer.from(expected));
  const fresh = Math.abs(Date.now() / 1000 - Number(parts.t)) < 300;
  return valid && fresh;
}

// Body: { "event": "call.completed", "payload": { ... }, "timestamp": "..." }

Check the signature before acting on an event in Capsule CRM. The secret is the one you set when you add the webhook in IntelDialix settings.

FAQ

Frequently asked questions

How does IntelDialix connect to Capsule CRM?

Through webhooks and custom tools. IntelDialix posts call events to a Capsule CRM endpoint you choose, and agents can call Capsule CRM during a conversation using an HTTP tool you configure in the agent editor.

Which events can Capsule CRM receive?

IntelDialix sends events such as call.initiated, call.inbound, call.completed, call.failed, campaign.started, campaign.completed. Each delivery includes a JSON payload and an X-Dialix-Signature header you can verify with your webhook secret.

Do I need a developer to set this up?

You need an HTTPS endpoint in Capsule CRM that can receive webhooks — many tools provide one — and, for mid-call actions, an endpoint the agent can call. Building the agent itself needs no code.
