## What it does

The skill explains Meta Conversions API architecture, including how browser Pixel events relate to server-side delivery. It covers event parameters, customer-data hashing, deduplication, Aggregated Event Measurement, and implementation approaches. Ask for a general guide or focus on a topic such as purchase events or server-side GTM.

In Claude Code, invoke it with `/meta-capi` and add a topic to narrow the answer. The reference includes implementation examples; with Cogny MCP connected, the skill can also inspect pixels, ad accounts, and campaign data. It works as a reference without connected accounts, but checking your configuration requires MCP. Install with `npx skills add cognyai/claude-code-marketing-skills --skill meta-capi -a claude-code`.
