RingCentral Webhooks
When to Use This Skill
- How do I receive RingCentral webhooks?
- How do I complete the RingCentral Validation-Token handshake?
- How do I verify RingCentral notifications with a Verification-Token?
- How do I create a RingCentral subscription (
POST /restapi/v1.0/subscription)? - Why is my RingCentral subscription getting blacklisted?
- How do I handle
message-store,presence, ortelephony/sessionsevents?
Verification (core)
RingCentral does not HMAC-sign webhooks and does not follow the Standard Webhooks spec. Authenticity relies on two mechanisms:
- Validation-Token handshake (mandatory). When a subscription is created or
renewed, RingCentral sends a request carrying a
Validation-Tokenrequest header. Your handler must echo that exact value back in aValidation-Tokenresponse header and return200— fast (within a few seconds). No body is required. - Verification-Token (optional). Set an arbitrary
verificationTokenstring on the subscription. RingCentral then sends it as aVerification-Tokenheader on every notification. Compare it (timing-safe) to reject spoofed requests.
Node:
const crypto = require('crypto');
// Timing-safe string compare for the Verification-Token header.
function tokenMatches(received, expected) {
const a = Buffer.from(received || '', 'utf8');
const b = Buffer.from(expected || '', 'utf8');
if (a.length !== b.length) return false;
return crypto.timingSafeEqual(a, b);
}
// In your POST handler:
const validationToken = req.get('Validation-Token');
if (validationToken) { // 1. handshake — echo + 200
res.set('Validation-Token', validationToken);
return res.status(200).json({ status: 'ok' });
}
if (EXPECTED_TOKEN && !tokenMatches(req.get('Verification-Token'), EXPECTED_TOKEN)) {
return res.status(401).json({ error: 'Invalid verification token' }); // 2. auth
}
Python:
import hmac
# 1. handshake — echo the Validation-Token back and return 200:
# if validation_token: return Response(headers={"Validation-Token": validation_token})
# 2. optional per-notification auth:
def token_matches(received: str, expected: str) -> bool:
return hmac.compare_digest(received or "", expected or "")

Common Event Types
RingCentral events are identified by the event filter (an API resource path)
in the notification's event field, not by a short name. Common filters:
| Event filter | Triggered When |
|---|---|
/restapi/v1.0/account/~/extension/~/message-store |
New message (SMS, voicemail, fax) |
/restapi/v1.0/account/~/extension/~/message-store/instant?type=SMS |
Inbound SMS (instant) |
/restapi/v1.0/account/~/extension/~/presence |
Extension presence changes |
/restapi/v1.0/account/~/telephony/sessions |
Call (telephony session) lifecycle |
/restapi/v1.0/account/~/extension/~/telephony/sessions |
Per-extension call events |
/restapi/v1.0/account/~/extension |
Extension created/updated/deleted |
For the full event filter reference, see RingCentral Event Types.
Important Headers
| Header | Direction | Description |
|---|---|---|
Validation-Token |
request → response | Handshake token to echo back on subscribe/renew |
Verification-Token |
request | Your configured token, sent on every notification |
Environment Variables
# Optional shared secret; set as `verificationToken` when creating the subscription.
RINGCENTRAL_VERIFICATION_TOKEN=your_verification_token
Local Development
# Start tunnel (no account needed). Address must be HTTPS — the tunnel provides it.
npx hookdeck-cli listen 3000 ringcentral --path /webhooks/ringcentral
