How do I verify webhooks came from my system?

Sign inbound requests with HMAC-SHA256 in the X-Webhook-Signature header and Voxworks rejects anything that doesn’t match.

Can I start calls from my own app?

Yes. Use the REST API to create a call, or start a web call session for in-browser conversations.

What Voxworks does with Webhooks & REST API

For systems without a built-in integration, Voxworks gives you inbound webhooks to start automations, a Send Webhook tool for data during the call, post-call webhooks and a REST API for contacts, calls and lists.

Inbound webhooks

Start an automation from any system, with optional signature checks and idempotency keys.

Data during the call

Look up records in your system mid-call or at call start and use them in the conversation.

Post-call webhooks

Send call results to your endpoint, retried on failure with an ID for de-duplication.

REST API

Create contacts and calls, cancel, reschedule or retry calls, read results and manage lists.

Web calls

Start a voice session from your own website or app.

Setup

Connect Webhooks & REST API in 3 steps

01
Generate an API key in Settings → API Keys.
02
Create an automation with an Inbound Webhook trigger, or add the Send Webhook tool to a script step.
03
Use the API reference for endpoints and webhook payloads.

Good to know

Webhooks sent during a call time out after 10 seconds, so keep those endpoints fast.
Inbound webhook payloads are limited to 100 KB.
