No separate Meta fee — engineering/setup cost on your platform; Adexcell includes baseline CAPI on clothing builds.

Use both; deduplicate event_id so Meta does not double-count.

Does CAPI work for COD?

Yes — fire Purchase on order placed or courier-confirmed, per your ops policy (document it).

How long to implement?

Days on existing Adexcell stack; weeks if checkout still lives in Messenger only.

What is Meta CAPI for Bangladesh ecommerce?

Meta Conversions API (CAPI) sends server-side purchase events to Facebook — critical when browser pixels miss iOS and in-app traffic.

Browser-only Meta Pixel under-reports purchases in 2025–2026 — especially mobile Facebook traffic in Bangladesh. Conversions API (CAPI) sends order events from your server so ad accounts optimize on real COD/prepaid completions.

What is Meta CAPI?

Direct answer

CAPI (Conversions API) is Meta’s server-side channel that posts conversion events (e.g. Purchase) from your backend to match and improve signal beyond the browser pixel alone.

Why Bangladesh clothing brands need CAPI

Direct answer

Fashion traffic is mobile-heavy; inbox selling hides purchases from Meta; CAPI + pixel deduplication often yields 25–40% efficiency gains once SKU landers and COD checkout exist.

CAPI without owned checkout fails

Direct answer

CAPI needs a definitive purchase event from your platform — Messenger ‘replied’ is not a purchase. Owned checkout with order IDs is the prerequisite.
