A reference guide for sending website and app actions, such as purchases or sign-ups, to Meta’s advertising system through its Conversions API. It covers event types, hashing customer details, duplicate-event handling, privacy settings, implementation examples, and testing.

Use it to plan or check a Meta Conversions API integration, choose events, protect customer data with hashing, prevent duplicate conversions, and test the setup.

It helps developers understand how to set up conversion tracking when browser-based tracking is incomplete or unreliable. It also reduces errors from duplicated events or improperly handled customer information.

Origin unknown No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00036	$0.07371
Opus 5.5	$0.00014	$0.02948
Sonnet 5.5	$0.00007	$0.01474
Haiku 4.5	$0.00004	$0.00737

Measured 25d ago against content hash 6fe68d7e8080, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

meta-capi 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 25d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What this file has done since we first saw it

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.
