Meta Conversions API: The Complete Setup Handbook with Vighnesh S

Most Conversions API setups are accepted by Meta and still do half the job. The event arrives, the API returns success, and nobody finds out for months that the phone numbers were hashed without a country code or that fbc never made it from the landing page to the order.

This handbook covers the whole thing. Why the API exists and what the browser stopped telling you. The anatomy of an event, field by field. How to normalise and hash every customer identifier, and which ones must never be hashed. How deduplication actually works, and what happens when it quietly fails. The four ways to set it up — partner integration, Meta's Gateway, server-side GTM, and direct code — with an honest view of which one you should pick. Then verification, Event Match Quality, and twelve failure modes with the fix for each.

Written for marketers who need to understand what their developer is doing, and developers who have been handed a ticket and a documentation link. Code examples in Node and Python. No prior API experience assumed.
