Set Up Webhook Tech Stack Changes Alerts via API
Short summary
Webhooks eliminate polling waste by pushing notifications only when monitored domains change their tech stack. DetectZeStack delivers signed payloads on daily/weekly schedules for Slack integration or custom handling. Detect buying signals (Stripe adoption), security risks (WAF removal), and scaling patterns (infrastructure migration) in real time.
- •Replace inefficient polling with event-driven webhooks that notify only on actual tech stack changes
- •Create subscriptions, enable monitoring intervals (daily/weekly), verify HMAC-SHA256 signatures, integrate with Slack
- •Track competitor moves, client security vulnerabilities, and infrastructure decisions that correlate with scaling or acquisition readiness
