ConvertFlow → AppsFlyer · Conversion tracking
Connecting ConvertFlow to AppsFlyer
ConvertFlow overlays personalised CTAs, quizzes and popups on an existing site, which means it changes what visitors see without changing the page they landed on. AppsFlyer exists because mobile app attribution is a different problem from web attribution, and on iOS a large share of it is now aggregated and delayed by design rather than by accident. The join between them succeeds or fails on one thing: whether the AppsFlyer device identifier, appsflyer_id reaches the ConvertFlow conversion before the conversion happens, because AppsFlyer can only match a conversion it can tie back to a click it recognizes.

Why this join usually fails
The AppsFlyer device identifier, appsflyer_id never reaches ConvertFlow
The single most common cause. Overlays render after page load and may capture the submission before your own analytics sees it.
Two systems changing the same page
Site changes and overlay changes both affect conversion rate, and they are managed by different people on different schedules. Without the overlay campaign on the record, neither team can attribute an improvement.
Web conversions sent to a mobile attribution platform
This is the common error and it produces confident nonsense. A purchase made on your website has no device identifier and no install behind it. AppsFlyer will either discard it or attribute it to nothing, and the revenue disappears somewhere between the two systems without anyone noticing it went.
Nothing reconciles afterwards
An upload that succeeds is not an upload that matched. AppsFlyer shows the event on the raw data export with its attributed media source. Check the raw export, not the aggregate dashboard, and confirm the event carries a device identifier rather than landing as organic.
Architecture
How ConvertFlow and AppsFlyer actually connect
Two systems that know nothing about each other. Everything below exists to give them one shared reference.
Step 1
ConvertFlow holds the truth
Because the overlay is separate from the page, a visitor's experience is the page plus whatever ConvertFlow decided to show. Neither alone explains the outcome.
Step 2
AppsFlyer needs a click to match
AppsFlyer needs the device identifier and an event name it recognizes, plus the revenue value for in-app purchases. A server event about a user with no linked device cannot be attributed to an install.
Step 3
The identifier is the bridge
The AppsFlyer device identifier, appsflyer_id, captured at the visit and carried into the ConvertFlow conversion. Without it there is nothing to join on and no tool fixes that.
Step 4
The event source decides reliability
Send qualified outcomes with the overlay campaign attached.
Step 5
Deduplication at the destination
AppsFlyer deduplicates in-app events by its own event identifier. Sending the same purchase from both the SDK and your server produces two events and double-counts revenue in every dashboard downstream, including the ad networks AppsFlyer forwards to.
Diagnose it honestly
Working vs. broken, side by side
Both states look identical from the AppsFlyer dashboard, which is why this runs for months before anyone notices.
Normal — not a fault
The AppsFlyer device identifier, appsflyer_id present on the conversion
Visible on the record itself in ConvertFlow, not merely captured somewhere on the site.
Sent from your CRM or order record
Server-side, so it does not depend on the customer's browser still being there.
Deduplicated correctly
AppsFlyer deduplicates in-app events by its own event identifier. Sending the same purchase from both the SDK and your server produces two events and double-counts revenue in every dashboard downstream, including the ad networks AppsFlyer forwards to.
Reconciles with the source
AppsFlyer's count and ConvertFlow's records agree within a few percent over a closed window.
Actually broken
The AppsFlyer device identifier, appsflyer_id missing on most records
Overlays render after page load and may capture the submission before your own analytics sees it.
Sent from the browser
Anyone who closes the tab, blocks the script or converts without a page load is invisible. Site changes and overlay changes both affect conversion rate, and they are managed by different people on different schedules. Without the overlay campaign on the record, neither team can attribute an improvement.
Counted twice, or not at all
This is the common error and it produces confident nonsense. A purchase made on your website has no device identifier and no install behind it. AppsFlyer will either discard it or attribute it to nothing, and the revenue disappears somewhere between the two systems without anyone noticing it went.
Nobody has reconciled it
The dashboard shows a number and no one has compared it to ConvertFlow. A wrong number that nobody checks is indistinguishable from a right one.
Diagnostic sequence
Diagnostic order
Each step rules out a class of cause. Run them in order and the last one usually has a single explanation standing.
- 1
Count conversions carrying the AppsFlyer device identifier, appsflyer_id
The ceiling on everything else. Do this before debugging anything downstream.
- 2
Follow one real conversion end to end
From the ad click through ConvertFlow and into AppsFlyer.
- 3
Record which overlay campaign was active on every conversion
It is a field, and it is what makes the two systems' effects separable.
- 4
Check what share of your revenue happens in the app at all
If most purchases are on the web, AppsFlyer is not your conversion destination and the work belongs somewhere else entirely.
- 5
Read the match rate, not the success message
AppsFlyer shows the event on the raw data export with its attributed media source. Check the raw export, not the aggregate dashboard, and confirm the event carries a device identifier rather than landing as organic.
Source-of-truth validation
How it gets proven
Against ConvertFlow's own records, not against either platform's dashboard.
- The AppsFlyer device identifier, appsflyer_id confirmed present on a live conversion.
- A real conversion followed from click through ConvertFlow to AppsFlyer.
- In-app revenue events reconciled per transaction against your billing system, with the organic share stated rather than assumed away.
- Qualified outcomes reconciled by overlay campaign against imported conversions.
- Reconciled over a fully closed window, matched per record rather than on totals.
- Re-checked 30 days later.
Straight talk
When you don't need this
Worth reading before paying anyone, including us.
- If AppsFlyer already reports conversions that reconcile against ConvertFlow's records within a few percent, this join is working and there is nothing to buy.
- Measure identifier coverage yourself first — pull your last hundred conversions and count how many carry the AppsFlyer device identifier, appsflyer_id. Ten minutes, free, and it tells you whether any of this is worth doing.
- If you run no overlays, the page alone explains the outcome and this complexity does not apply.
- If you have no mobile app, this is not a destination for you. If you have one but sell mostly on the web, send web conversions to your ad platforms directly and use AppsFlyer only for install and in-app events.
Who this is for
Honest about who we’re a fit for.
We don’t take every project. Here’s how to tell if we’re right for you.
You’re a great fit if…
- You run ConvertFlow → AppsFlyer (or are migrating to it)
- You spend $5K+/month on paid ads (Meta, Google, TikTok, Microsoft, LinkedIn)
- Your reported ROAS doesn’t match what your bank account is saying
- You want to own your tracking stack — no monthly SaaS fees forever
- You have 2–4 days to do this once and never think about it again
Skip us if…
- You spend less than $500/month on paid ads (browser pixel is fine)
- You want a SaaS dashboard with monthly fees forever (Triple Whale, Hyros)
- You need attribution modeling — we fix the data foundation, not multi-touch reports
- You want a 6-month enterprise consulting engagement (we ship in 4 days)
- You expect us to manage your ad accounts (we don’t — that’s a different service)
If you’re still unsure,book the call anyway— we’ll tell you straight whether we can help.

Got questions?
The honestanswers.
No buzzwords, no upsell. If we don’t know, we say so.
01Why aren't my ConvertFlow conversions showing in AppsFlyer?
Almost always because the AppsFlyer device identifier, appsflyer_id never reached the ConvertFlow conversion. Overlays render after page load and may capture the submission before your own analytics sees it. Measure coverage before debugging the dispatch.
02What identifier does AppsFlyer need?
AppsFlyer assigns its own device ID and matches installs to clicks through referrer data on Android and Apple's frameworks on iOS. There is no durable cross-device identifier. On iOS without ATT consent, attribution falls back to SKAdNetwork, which returns aggregated conversion values on a delay with no user-level detail at all — so a share of your installs will be attributable only in aggregate, permanently.
03Where should the event come from?
Your CRM or order record. Send qualified outcomes with the overlay campaign attached.
04How do I know it worked?
AppsFlyer shows the event on the raw data export with its attributed media source. Check the raw export, not the aggregate dashboard, and confirm the event carries a device identifier rather than landing as organic.
