What it does

SENDS A SERVER-SIDE CONVERSION EVENT to Meta (Conversions API) — the fix for conversions lost to iOS 14+ / ad-blockers / cookie limits, and the only way to report sales that happen off the website (CRM, phone, showroom, POS).

pixel_id from list_meta_pixels. event_name: Purchase | Lead | CompleteRegistration | AddToCart | ViewContent | Contact | Schedule ... At least ONE identifier is required: email, phone, external_id, fbc or fbp. Email/phone are SHA-256 hashed locally; raw personal data never leaves the server. event_id: the SAME id as the browser pixel lets Meta de-duplicate automatically (no double counting). action_source: website | phone_call | chat | email | physical_store | system_generated | other (phone_call/physical_store for offline sales). test_event_code: routes the event to Meta's Test Events view without touching real reporting. confirm=false previews; confirm=true sends.

How to use it

You don't call tools by name. Write what you want in ChatGPT, Claude or another assistant connected to Opus Growth, in your own words; it picks this tool when it fits.

Because this tool changes your account, your assistant first shows a preview of exactly what will change. Nothing is applied until you say yes, and every applied change is written to your audit log.
