Webhooks & Events. Real-Time, Always.
Perception X2 webhooks deliver real-time event notifications directly to your endpoints — sentiment shifts, narrative threats, crisis triggers, and campaign completions arrive the instant they occur. No polling. No delays. No missed signals.

Event-Driven Architecture for Mission-Critical Intelligence
Perception X2 webhooks provide the event-driven backbone that connects autonomous engines to your external systems, dashboards, and workflows. Push-based delivery eliminates polling.
Most perception management platforms rely on polling-based integration — developers repeatedly query APIs to check for new data, wasting bandwidth, increasing latency, and creating blind spots between polling intervals. Perception X2 eliminates polling entirely through a webhook-driven event architecture that pushes notifications to your endpoints the instant events occur.
Perception intelligence unfolds in real-time — sentiment shifts across platforms, narrative threats emerge in minutes, and crisis triggers demand immediate response. A polling-based integration that checks every 60 seconds misses 59 seconds of context. Perception X2 webhooks deliver event notifications with sub-500ms latency from detection to delivery.
Perception X2 webhooks are not simple HTTP callbacks. They are an enterprise-grade event delivery system with HMAC-SHA256 signature verification, configurable retry policies with exponential backoff, event filtering and subscription management, delivery tracking and audit logging, and sandbox testing environments.
The Limitations of Polling-Based Integration
Organizations that integrate perception intelligence through polling-based APIs face fundamental limitations — latency gaps, resource waste, and operational blind spots. Webhooks eliminate these problems.
Latency Gaps
When your integration polls every 30 seconds, events that occur immediately after a poll sit unprocessed for up to 30 seconds. For crisis detection, that gap is catastrophic.
Resource Waste
Polling consumes API quota regardless of whether new data exists. An integration polling 10 endpoints every 30 seconds makes 28,800 API calls per day — most returning unchanged data.
Inconsistent Data Freshness
Different polling intervals across integrations create inconsistent data freshness. Your CRM might receive updates every 5 minutes while your dashboard polls every 30 seconds.
Scaling Complexity
As integrations proliferate, polling infrastructure scales linearly. Managing polling schedules and handling rate limit collisions grows faster than the integrations themselves.
No Push-Based Triggers
Polling cannot trigger immediate responses. Automated response workflows cannot start until polling discovers the event — bounded by polling frequency.
Network Overhead
Polling connections create network overhead — constant TCP connections, request/response cycles, and proxy infrastructure that drains resources.
Missed Events
When systems are down, polling misses events entirely. Webhook delivery ensures events are queued and retried until acknowledged.
No Event Filtering
Polling retrieves all data; filtering happens client-side. Webhooks deliver only the events relevant to your integration — reducing processing overhead.
Push-Based Event Delivery With Enterprise Reliability
Perception X2 replaces polling with a push-based webhook architecture that delivers event notifications to your endpoints the instant they occur. Designed for enterprise reliability, security, and operational transparency.
Push-Based Delivery
When Perception X2 detects an event, the platform immediately constructs a webhook payload and POSTs it to your configured endpoint. No polling required. No latency gaps.
Authenticated Payloads
Every webhook delivery includes an X-Perception-Signature header containing an HMAC-SHA256 signature. Your endpoint verifies the signature before processing.
Configurable Retry
When your endpoint returns a non-2xx status, Perception X2 retries with exponential backoff. Configurable per webhook subscription. Failed deliveries enter dead letter queue.
Event Filtering
Configure which events trigger deliveries through subscription rules. Filter by event type, campaign scope, engine identifier, severity threshold, or custom tags.
How Perception X2 Webhooks Work
Event Detection
A Perception X2 engine detects a significant event — sentiment shift, narrative threat, crisis trigger, or campaign milestone.
Subscription Matching
The Event Router evaluates the event against all active webhook subscriptions, matching event type, campaign scope, and filtering rules.
Payload Construction
The Webhook Dispatcher constructs a JSON payload containing the full event context, metadata, and delivery identifiers.
HMAC Signing
The payload is signed with HMAC-SHA256 using your endpoint's signing secret, and the signature is included in the X-Perception-Signature header.
Delivery & Acknowledgment
The signed payload is POSTed to your endpoint with a 30-second timeout. A 2xx response acknowledges receipt. Non-2xx triggers retry with exponential backoff.
Webhook System Capabilities
Sub-500ms Delivery
Event detection to endpoint notification in under 500ms. Real-time push eliminates polling latency.
HMAC-SHA256 Signatures
Every payload cryptographically signed. Your endpoint verifies origin and integrity before processing.
Configurable Retry
Exponential backoff retry policies. Configurable per subscription. Dead letter queue for failed deliveries.
Event Filtering
Filter by event type, campaign scope, engine identifier, severity threshold, or custom tags. Reduce processing overhead.
Dead Letter Queue
Failed deliveries that exhaust retry attempts enter dead letter queue. Manual replay supported. API and dashboard access.
Delivery Tracking
Comprehensive delivery metrics. Real-time visibility into delivery success, latency, and retry behavior.
Common Webhook Integration Patterns
Crisis Alert Routing
Configure webhooks for crisis events. Route critical alerts to Slack, PagerDuty, or incident response systems. Severity-based escalation.
Sentiment Threshold Alerts
Trigger alerts when sentiment crosses configured thresholds. Push notifications to dashboard, email, or mobile.
Narrative Threat Detection
Receive notifications when narrative threats are detected. Trigger automated response workflows and counter-narrative deployment.
Campaign Completion Notifications
Trigger downstream workflows when campaigns reach completion criteria. Sync to CRM, marketing automation, or analytics platforms.
Multi-Platform Deployment Status
Receive notifications when multi-platform deployments complete. Track success and failure counts per platform.
