> Server-side conversion API for B2B SaaS marketing, by Marc Stevens. One HTTPS call (POST /api/v1/track) normalizes and SHA-256 hashes user data, deduplicates on event_id for 72 hours, and forwards the event to the Meta Conversions API. Self-serve: no tag manager, no CDP, no sales call.

## Pricing
- Free: 1,000 events per month.
- Then CA$2 per 1,000 events (overage checkout is currently Stripe test mode).

## Status
- Live: Meta Conversions API forwarding (per-workspace pixel ID + access token), event_id dedup, hashing, Test Events support.
- Coming soon: Google Enhanced Conversions (payload preview only today).
- Roadmap: LinkedIn Conversions API (not forwarded yet).
