meta-capi-implementation-guide

meta-capi-implementation-guide is a skill for Claude Code from Ad-Superpowers/ad-superpowers-plugin. It costs 90 tokens per session (2,622 once invoked), scanned A, original, MIT.

An implementation guide for Meta Conversions API, or CAPI, which sends website or app conversion events from a server to Meta instead of relying only on a browser. It covers server-side tracking and matching duplicate events.

In plain words
What is it for?
Use it to plan CAPI setups for Shopify, WooCommerce, Magento, custom websites, or server-side Google Tag Manager, including event deduplication.
Why use it?
Browser tracking can lose conversion signals because of privacy controls, ad blockers, and cookie limits; server-side events provide another way to report conversions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

meta-capi-implementation-guide scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

CAPI Implementation Guide

Guide for implementing Meta's Conversions API (CAPI) for server-side tracking. CAPI is practically mandatory for any account spending >€1k/month — without it, you lose 20-40% of conversion signals (higher in markets with strong privacy regulations or high iOS share). Target Event Match Quality (EMQ) of 6.0+, with 7+ for Purchase events.

Why CAPI Is Mandatory (Not Optional)

Browser Tracking Challenges:
├── iOS 14.5+ App Tracking Transparency
├── Safari ITP (Intelligent Tracking Prevention)
├── Ad blockers (30%+ of users)
├── Cookie deprecation
└── GDPR/privacy regulations

CAPI Benefits:
├── Bypasses browser limitations
├── First-party data direct to Meta
├── Better Event Match Quality
├── Redundant tracking (Pixel + CAPI)
└── More accurate attribution

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
