Conversion APIকনভার্সন এপিআই
A conversion API is a server-to-server event protocol, such as Meta's Conversions API, Google's Enhanced Conversions or TikTok's Events API, that sends conversion data from the brand's server straight to the ad platform. It bypasses browser tracking that iOS ATT and ad blockers degrade, restoring 30–50% of the lost conversion signal.
What is Conversion API?
In practice
Conversion API is one of two technical lifts every Bangladeshi e-commerce stack must do post-iOS-14.5 (the other is first-party data). Server-side events restore 30–50% of the conversion signal lost from browser-side pixels. Public Pulse implements Meta CAPI alongside the browser pixel (dedup by event_id), so the platform sees both signals and Meta's bidding has clean attribution. Without CAPI, Meta's algorithm optimizes against a partial dataset and CPA inflates 20–40% over a 6-month decay curve.

Meta Conversions API (CAPI)
Meta Conversions API (CAPI) is server-to-server event tracking that sends conversions from a site or CRM to Meta's ad platform, recovering signal lost to iOS ATT and ad blockers. Because browser-side pixel firing drops 30–50% or more of events after iOS 14.5, sending the same events from the server gives Meta's bidding a more complete signal.

First-Party Data
First-party data is customer data a business collected directly from its own site, app, CRM, point-of-sale or call centre, as opposed to third-party data bought from brokers or rented from ad platforms. It is the strategic asset for Bangladeshi brands as Meta and Google narrow third-party signal through iOS ATT and cookie deprecation.

ROAS (Return on Ad Spend)
ROAS, or Return on Ad Spend, is the revenue generated for every BDT spent on advertising; a ROAS of 4× means BDT 4 of revenue per BDT 1 of ad spend. It is the headline metric for e-commerce paid media, but in isolation it can mislead, so it should be read alongside the new-versus-returning customer split.
