Meta Conversions API (CAPI) is not a Bangladesh-specific product — but Bangladesh clothing ad accounts suffer most when signal is weak (mobile Facebook, COD confirmation delays). This guide is implementation-neutral.
What you send through CAPI
Direct answer
At minimum: Purchase with value, currency (BDT), content_ids/SKU, and customer parameters (hashed phone/email where policy allows). Optional: AddToCart, InitiateCheckout for funnel diagnostics.
Prerequisites on your stack
Direct answer
Owned checkout that creates order records, Meta Pixel on site, Business Manager access, Dataset/Pixel ID, access token stored server-side, and a documented rule for when COD counts as ‘purchase’.
Deduplication with browser Pixel
Direct answer
Send the same event_name with matching event_id from browser and server so Meta deduplicates — prevents double counting while improving match rate.
