List the enabled Conversions
Every enabled Conversion, compiled: its key, the platforms it sends to and how (from the page, the server or both — never the platforms’ own IDs), and what triggers it (counts only — never the forms, pages or links themselves). Another system uses it to find the Conversion to post facts to: triggers.external: true accepts POST /conversion-event/external, naming the Conversion by its id or key.
Access: an API key with conversions:read — or its group master ads:all, or admin:all — or a signed-in user holding the conversion-events:view permission. Anonymous callers get 404.
Rate limit: the key’s own reads-per-minute limit, set when the key is created (default 600); over it, 429 with Retry-After.
