# Meta Ads Signal Engine An engineering operating system for reliable Meta Ads conversion tracking, Pixel & Conversions API (CAPI) implementation, deterministic event deduplication, customer matching, and attribution preservation. ## Verify the API version before writing code **Never hardcode a Graph API version from memory or from these notes.** Meta ships a new version roughly every quarter and retires each one after about two years, so any version written down here is stale the moment it is written. | Check | Where | | --- | --- | | Current Graph API version | `https://developers.facebook.com/docs/graph-api/changelog` | | Conversions API parameters | `https://developers.facebook.com/docs/marketing-api/conversions-api/parameters` | Pin the version in **one** exported constant so a bump is a one-line change, never a grep across trackers: ```typescript // Verified against the changelog on <date>. Re-check before bumping. export const META_GRAPH_API_VERSION = 'v26.0'; const endpoint = `https://graph.facebook.com/${META_GRAPH_API_VERSION}/${pixelId}/events`; ``` Reference snippets below are illustrative of *structure*, not of the current version string. ## Core Philosophy Tracking quality alone does not guarantee lower Cost Per Acquisition (CPA), but sending **correct, server-authoritative, deduplicated, and matchable conversion signals** ensures Meta's auction algorithms learn from valid business outcomes. $$\text{Meta Ad Click (_fbp, _fbc)} \longrightarrow \text{Bro
