Serverless Autoscaling Postgres/Databases, Vector & Storage
Connect Neon Postgres to IntelDialix voice agents
Instant database branching for testing new voice agent configurations against production telephony datasets.
In short
You connect Neon Postgres to IntelDialix in two directions. When a call starts or ends, IntelDialix sends a signed webhook to Neon Postgres with the transcript and outcome. During a call, an agent can reach Neon Postgres 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 Neon Postgres.
- 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
- 02
The agent uses Neon Postgres mid-call
When the conversation needs data, the agent runs a custom tool: an HTTP request to Neon Postgres with the details it has collected.
Custom tool → Serverless Postgres WebSockets
- 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
- 04
Neon Postgres receives the result
A signed webhook delivers the call event to your Neon Postgres endpoint, and is retried automatically if the delivery fails.

Example
// Verify an IntelDialix webhook before trusting it in Neon Postgres.
// 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 Neon Postgres. The secret is the one you set when you add the webhook in IntelDialix settings.
FAQ
Frequently asked questions
How does IntelDialix connect to Neon Postgres?
Through webhooks and custom tools. IntelDialix posts call events to a Neon Postgres endpoint you choose, and agents can call Neon Postgres during a conversation using an HTTP tool you configure in the agent editor.
Which events can Neon Postgres 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 Neon Postgres 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.
