Meta Pixel & Conversions API Setup so Meta sees every sale.
Meta's ad system is only as smart as the data you give it. Digiil sets up Meta Pixel and Conversions API in Bangladesh with proper deduplication and strong match quality, so your Facebook and Instagram ads find real buyers.
Browser + server eventsDeduplicated by event IDHigh EMQ scores
Quick answer
Meta Conversions API, or CAPI, sends website and offline events directly from your server to Meta, alongside the Meta Pixel in the browser. Together they give Meta more complete and reliable data. A proper setup deduplicates matching events with an event ID, sends hashed customer details for strong event match quality, and respects user consent.

How CAPI works
Pixel alone vs. Pixel + CAPI.
| Pixel + Conversions API | Pixel only | |
|---|---|---|
| Data source | Browser and your server | Browser only |
| Ad blockers | Server events still arrive | Events often lost |
| Browser cookie limits | Less affected | Shorter tracking windows |
| Offline sales | Can be sent from CRM | Not possible |
| Ad optimization | Stronger signals | Weaker signals |

Amanat Mossalli TajuDigital Strategist, Digiil
Updated November 2026Think of Meta's ad algorithm as a salesperson who learns from every sale. If it only hears about half your sales, it learns the wrong lessons. It targets the wrong people and your costs rise. That is exactly what happens when you rely on the Pixel alone.
The fix is the Meta Conversions API. As a tracking agency in Bangladesh, Digiil sets up Pixel and CAPI together, so Meta sees a fuller, more accurate picture.
What is Meta Conversions API?
The Meta Pixel runs in the visitor's browser. Conversions API runs on your server. When someone buys, both can send the event to Meta. If the browser event is blocked, the server event still arrives. Meta's own Conversions API documentation recommends using both together.
Deduplication: the step most setups miss
If both the Pixel and CAPI send a purchase, Meta could count it twice. To stop this, both events must share the same event name and the same event_id. Meta then keeps one and drops the duplicate. We test this on every setup.
Event match quality
Meta gives each event an event match quality score from 0 to 10. It shows how well Meta can link the event to a real account. Higher is better. You raise it by sending allowed, hashed customer details:
- Email and phone number, hashed.
- First and last name, city and country.
- The fbp and fbc browser IDs.
- IP address and browser user agent.
Bangladesh tipMany buyers here check out with a phone number, not email. Sending the hashed phone number in the right format often gives the biggest match quality boost.
Ways to set up CAPI
| Method | Good for | Trade-off |
|---|---|---|
| Platform integration (Shopify) | Quick start | Less control |
| Plugin (WooCommerce) | Simple stores | Can conflict, limited data |
| Server-side GTM | Most brands | Small server cost |
| Direct API | Apps and custom systems | Needs developers |
For most brands, we recommend server-side GTM. It is flexible, works for Meta, Google and TikTok at once, and keeps you in control.

Sending offline and CRM events
For lead businesses, real value happens after the form. We send events like "qualified lead" or "deal won" from your CRM to Meta. Then your Meta ads learn to find buyers, not just form fillers.
Key takeaways
- Use Pixel and CAPI together for complete data.
- Deduplicate with the same event_id.
- Raise match quality with hashed customer details.
- Server-side GTM is the best fit for most brands.
- Send CRM events so Meta learns what a real sale looks like.
FAQ
Meta CAPI questions.
Still have a question?
Message us on WhatsApp or email info@digiil.com. A real strategist replies within 12 hours.
What is the Meta Conversions API?
It is a way to send website, app and offline events directly from your server to Meta. Used with the Pixel, it gives Meta more complete data for ad optimization and measurement.
Do I still need the Meta Pixel with CAPI?
Yes. Meta recommends using both. The Pixel captures browser signals, and CAPI adds reliable server events. Deduplication stops double counting.
What is a good event match quality score?
Higher is better on Meta's 0 to 10 scale. Scores in the "good" or "great" range usually mean you are sending enough customer details for strong matching.
How do I fix duplicate events in Meta?
Send the same event name and the same event_id from both the Pixel and the Conversions API, so Meta can keep one and remove the other.
Does CAPI work with WooCommerce and Shopify?
Yes. Both have integration options. For more control and better data, many brands use server-side GTM instead.
Is Conversions API privacy-safe?
When set up properly, customer details are hashed before sending and events follow user consent and Meta's terms.
