Webhooks and Core API: Seamless Integration with Enterprise Infrastructure
Connect messaging channels to ERP, CRM, and databases in real time. Bidirectional webhooks with HMAC-SHA256 cryptographic signatures, guaranteed idempotency, and Core REST API with sub-25ms response times.
curl -X POST https://api.volbor.org/v1/webhooks \
-H 'Authorization: Bearer sec_live_9a8f2e' \
-H 'X-Idempotency-Key: idemp_7b3a1c' \
-d '{"event": "payment.succeeded", "url": "https://corp.com/wh"}'{"status": "subscribed", "id": "wh_4f81"}Three Core Integration Mechanisms
Architected by engineers for engineers, providing complete control over enterprise data flows.
1. Outbound Calls from Bot Flows
A visual node in your bot flow dispatches a REST request to your backend. The bot transmits parameters, receives a JSON response, and maps variables into the live conversation.
2. Inbound Webhooks
An external ERP or payment gateway posts an event to a secure volbor URL. The platform identifies the contact, updates the deal stage, or triggers an automated flow.
3. Platform Core REST API
A comprehensive programmatic API to create contacts, export conversation histories, dispatch transactional messages, and manage access permissions.
Real-Time Webhook Events
Subscribe to key customer lifecycle triggers to synchronize with your corporate database:
Inbound customer message from any messaging channel with full body text and attachments.
Deal transition to a new CRM Kanban stage with recorded deal value and assigned owner.
Successful invoice payment confirmation via Stripe or an international banking gateway.
Update to contact qualification score or promotion to Hot Lead status.
Conversation escalation from an automated bot flow to a live agent in Unified Inbox.
Creation or mutation of an industry-specific entity (booking, property lot, work order).
HMAC-SHA256 Signatures and Source Verification
Every webhook includes a cryptographic signature in the `X-Signature-SHA256` header, preventing replay attacks and payload tampering.
- ✓Man-in-the-Middle protection via TLS 1.3
- ✓Zero-downtime secret key rotation without API disruption
- ✓Fixed whitelist pool of volbor server IP addresses
- ✓Full compliance with GDPR and ISO 27001 enterprise standards
const crypto = require('crypto');
function verifyWebhook(payload, signature, secret) {
const hmac = crypto.createHmac('sha256', secret);
const digest = 'sha256=' + hmac.update(payload).digest('hex');
return crypto.timingSafeEqual(Buffer.from(signature), Buffer.from(digest));
}Idempotency and Retry Ladder
Network failures never cause lost events or duplicate financial transactions.
X-Idempotency-Key Header
Guarantees that resending the same webhook during a network timeout will not create duplicate charges or second deals in CRM.
Exponential Backoff Retry Ladder
On 5xx errors from your endpoint, the system automatically retries delivery: 1 min, 5 min, 15 min, 1 hour, and 24 hours.
Dead Letter Queue (DLQ)
Failed events after exhausted retry attempts are held in quarantine with manual replay available in the dashboard.
High Throughput and Predictable Limits
The programmatic interface sustains thousands of concurrent calls per second with sub-second latency.
Median Core API Latency
Rapid response powered by an optimized runtime
Typed Error Format
Machine-readable error payloads with field-level validation
Cursor Pagination
Efficient export of millions of contacts without database degradation
Interactive Specification
Ready-to-use schemas for automated client and SDK generation
Bidirectional Sync with ERP and SQL Databases
How to unify enterprise master data with conversational chatbots without data drift.
Inbound Sync: Master data from ERP to volbor
When inventory balances or pricing update in ERP/SAP, your server sends a webhook, updating metaobjects and bot storefronts in under 50 ms.
Outbound Sync: Chat transactions to data warehouse
Upon order completion in the bot, the event streams to your corporate Data Lake or PostgreSQL database.
Developer Toolkit: Debugging and Network Call Auditing
Engineers get full tooling to inspect and debug webhooks directly within the dashboard.
1-Click Webhook Replay
Replay any historical webhook payload to verify backend bug fixes.
Distributed Trace-IDs
A unified end-to-end request identifier matching chat sessions to your internal server logs.
JSON Payload Inspector
Inspect exact request headers, payload bodies, HTTP status codes, and execution latencies.
Instant Telegram Alerts
Alert on-call engineers when 5xx error spikes occur on external endpoints.
4 Steps to Deploy Integrations into Production
A battle-tested engineering checklist for secure external system connectivity:
Align data schema
Define JSON payload structure, required attributes, and ID formats.
Configure endpoint and secret key
Generate HMAC secret key and register webhook URLs in the dashboard.
Sandbox testing
Simulate timeouts, HTTP 500 errors, and verify idempotency handling.
Production rollout
Launch live traffic sync with uptime monitoring and automated alerts.
Measurable ROI from API Integrations
Eliminate manual copy-pasting and reconcile fragmented system registries.
Faster integration rollouts [1]
Prebuilt webhook nodes and strict documentation reduce engineering cycles to days.
Hours spent on manual data entry [2]
Staff no longer copy addresses, order statuses, and payments between application windows.
Order error rate reduction [3]
Direct programmatic exchange of SKUs and invoices eliminates human error.
Monthly net operational savings [4]
Lower operational overhead on manual status reconciliation and order confirmations.
Frequently Asked Questions about Webhooks and Core API
What data format is used for data exchange?+
All requests and responses are transmitted in standard JSON over secure HTTPS with UTF-8 encoding.
What is the maximum timeout for webhook calls?+
The standard timeout for outbound calls from bot flows is 5–10 seconds, ensuring instant response times for the end user in chat.
What happens if an external server returns a 500 error?+
The bot flow routes to a graceful fallback branch: the bot apologizes for the delay and hands off to an agent, while the webhook enters the retry queue.
Is IP whitelisting supported?+
Yes. For maximum infrastructure security, the platform provides a fixed CIDR pool of outbound server IP addresses.
Is Bearer token authentication supported?+
Yes, you can configure custom HTTP headers, including Bearer JWT, Basic Auth, and custom API keys.
How do we test webhooks during local development?+
The developer portal includes an integrated Webhook Log viewer, 1-click test event dispatching, and support for local tunneling tools.
Are official SDKs available?+
Yes, typed SDKs are provided for TypeScript, Python, Go, and PHP, reducing setup to a few lines of code.
Can webhooks be sent to analytics platforms?+
Yes, message delivery, button click, and agent activity events can be piped into your enterprise Data Lake or BI system.
What are the Core API rate limits?+
The Core API architecture sustains thousands of concurrent requests per second using a Token Bucket algorithm without latency degradation.
Does data transmission comply with enterprise security standards?+
Yes, all data channels are secured with modern TLS 1.3 encryption in full compliance with GDPR and ISO 27001 requirements.
