About this Gig
Are your Meta App Ads suffering from data loss due to Apple's ATT?
To feed Meta's algorithm the data it needs to find paying users, you need the Meta Conversions API (CAPI).
As a Mobile Attribution Engineer with 8+ years of experience and 100+ projects (including GetYourGuide and Bridebook), I build pipelines that recover lost mobile data, working directly with your dev team or guiding them step by step.
What I will engineer for your app:
- ️App CAPI Integration: Connect Meta CAPI via your MMP (AppsFlyer, Adjust, Branch, Singular), Firebase, or directly via your backend server.
- Direct S2S Implementation: No MMP? No problem. I design the architecture and provide your developers with a clear, actionable implementation guide.
- Event Deduplication: Ensure your Meta App SDK and CAPI events are correctly deduplicated so you don't over-report conversions.
- SKAdNetwork (SKAN) Setup: Configure iOS conversion values so you can track performance even when users opt out of tracking.
The Result: Accurate attribution, EMQ score 7+ in Meta Events Manager, a smarter Meta ads.
Stop flying blind with your ad spend. Message me with your app's tech stack (MMP or Firebase) and let's fix your data

FAQ
Q: Do I need an MMP (Mobile Measurement Partner) for this?
A: Using an MMP (like AppsFlyer, Adjust, or Branch) is the industry standard and makes CAPI integration seamless. However, if you do not have an MMP, we can set up App CAPI using Firebase or a Google Tag Manager Server-Side container.
Q: Will this bypass the Apple ATT prompt (App Tracking Transparency)?
A: No tracking method bypasses Apple's privacy rules. However, App CAPI ensures you capture 100% of the data from opted-in users and provides Meta with the server-side signals needed to accurately model the conversions of opted-out users via SKAdNetwork.
Q: What is Event Deduplication and why is it required?
A: When we enable CAPI, Meta receives data from both your App SDK and your Server. Deduplication uses an event_id to merge these two signals. If this is not set up correctly, Meta will count one purchase as two, ruining your ad optimization. I ensure this is configured perfectly.
Q: Do you need access to my app's source code?
A: I do not need to edit your app's code directly. I will configure the server-side pipelines and dashboard settings. If SDK updates are required, I will generate the exact technical documentation and code snippets for your developers to paste in.
Q: What is Event Match Quality (EMQ)?
EMQ is Meta's 0–10 score measuring how accurately your server events match real Facebook user profiles. A low EMQ (below 6) means Meta can't identify who converted, so it can't find similar users for your campaigns.
Q: My Event Match Quality (EMQ) score is low. Can you improve it?
A: Definitely! Low EMQ is usually due to missing customer parameters or incorrect data formatting. I'll optimize your event parameters, implement proper customer data hashing, and typically improve EMQ scores to 7.0+ (green range).
Q: Do you support direct server-to-server CAPI setup without an MMP?
Yes. If your app doesn't use an MMP like AppsFlyer or Adjust, I design the S2S architecture and provide your development team with a detailed implementation guide covering endpoint setup, event payload structure, deduplication logic, and test verification in Meta Events Manager.
