Firefly → Segment · Conversion tracking
Connecting Firefly Reservations to Segment
Firefly serves smaller RV parks that switched from spreadsheets, which means the practical problem is usually data hygiene rather than attribution sophistication. Segment is a customer data platform rather than an ad network, so sending to it is not about matching a conversion — it is about putting one clean event where every other destination can read it. The join between them succeeds or fails on one thing: whether the userId and anonymousId reaches the Firefly reservation before the conversion happens, because Segment can only match a conversion it can tie back to a click it recognizes.

Why this join usually fails
The userId and anonymousId never reaches Firefly
The single most common cause. The booking engine is hosted, and a share of reservations are still entered by hand from phone calls.
Manually entered bookings with no source at all
A park taking half its bookings by phone and entering them by hand has half its revenue unattributed by construction. Tagging at entry is a process change, not a technical one, and it is the whole fix.
One bad event multiplied across every destination
Segment's value is fan-out, which is also its risk. An inconsistent identity or a duplicated event does not break one report — it breaks every connected tool simultaneously, and tracing it back is harder than debugging a direct integration.
Nothing reconciles afterwards
An upload that succeeds is not an upload that matched. Segment's debugger shows events arriving and which destinations accepted them. Arriving is not the test — check a destination you care about and confirm the event landed there with the identity intact, then reconcile against your own records.
Architecture
How Firefly and Segment actually connect
Two systems that know nothing about each other. Everything below exists to give them one shared reference.
Step 1
Firefly Reservations holds the truth
For a park moving off manual records, the first win is that reservations exist as data at all. Attribution is the second problem, not the first.
Step 2
Segment needs a click to match
Segment needs a consistent identity model — the same userId everywhere, an alias when an anonymous visitor becomes known, and event names that follow one spec. Feeding it inconsistent identities pushes the mess to every connected destination at once.
Step 3
The identifier is the bridge
The userId and anonymousId, captured at the visit and carried into the Firefly reservation. Without it there is nothing to join on and no tool fixes that.
Step 4
The event source decides reliability
Send completed stays at total value, with manually entered reservations tagged by source.
Step 5
Deduplication at the destination
Segment deduplicates on messageId within a window. Because it fans out to many destinations, a duplicate here becomes a duplicate everywhere, which makes idempotent messageIds more important than in any single-destination integration.
Diagnose it honestly
Working vs. broken, side by side
Both states look identical from the Segment dashboard, which is why this runs for months before anyone notices.
Normal — not a fault
The userId and anonymousId present on the reservation
Visible on the record itself in Firefly Reservations, not merely captured somewhere on the site.
Sent from the Firefly reservation record
Server-side, so it does not depend on the customer's browser still being there.
Deduplicated correctly
Segment deduplicates on messageId within a window. Because it fans out to many destinations, a duplicate here becomes a duplicate everywhere, which makes idempotent messageIds more important than in any single-destination integration.
Reconciles with the source
Segment's count and Firefly Reservations's records agree within a few percent over a closed window.
Actually broken
The userId and anonymousId missing on most records
The booking engine is hosted, and a share of reservations are still entered by hand from phone calls.
Sent from the browser
Anyone who closes the tab, blocks the script or converts without a page load is invisible. A park taking half its bookings by phone and entering them by hand has half its revenue unattributed by construction. Tagging at entry is a process change, not a technical one, and it is the whole fix.
Counted twice, or not at all
Segment's value is fan-out, which is also its risk. An inconsistent identity or a duplicated event does not break one report — it breaks every connected tool simultaneously, and tracing it back is harder than debugging a direct integration.
Nobody has reconciled it
The dashboard shows a number and no one has compared it to Firefly Reservations. 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 reservations carrying the userId and anonymousId
The ceiling on everything else. Do this before debugging anything downstream.
- 2
Follow one real conversion end to end
From the ad click through Firefly and into Segment.
- 3
Count what share of reservations are entered manually
That share is your unattributable base, and it is usually larger than the operator expects.
- 4
Check identity resolution before checking anything downstream
If anonymousId is never aliased to userId, every destination sees two people where there is one, and no downstream fix helps.
- 5
Read the match rate, not the success message
Segment's debugger shows events arriving and which destinations accepted them. Arriving is not the test — check a destination you care about and confirm the event landed there with the identity intact, then reconcile against your own records.
Source-of-truth validation
How it gets proven
Against Firefly Reservations's own records, not against either platform's dashboard.
- The userId and anonymousId confirmed present on a live reservation.
- A real conversion followed from click through Firefly to Segment.
- An anonymous session confirmed aliased to a known user, with the event visible in at least one downstream destination.
- Completed stays reconciled at total value, with the manually entered share stated.
- 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 Segment already reports conversions that reconcile against Firefly Reservations'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 reservations and count how many carry the userId and anonymousId. Ten minutes, free, and it tells you whether any of this is worth doing.
- If nobody will tag sources at entry, report online bookings honestly and label the rest unknown rather than guessing.
- If you send to one or two destinations, Segment is infrastructure you do not need — direct integrations are simpler and cheaper. It earns its place at genuine fan-out.
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 Firefly → Segment (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 Firefly conversions showing in Segment?
Almost always because the userId and anonymousId never reached the Firefly reservation. The booking engine is hosted, and a share of reservations are still entered by hand from phone calls. Measure coverage before debugging the dispatch.
02What identifier does Segment need?
Segment identifies people by anonymousId before they are known and userId afterwards, and the alias between them is what stitches a session to a customer. Click identifiers travel as event properties or traits rather than as a matching key — Segment does not match anything itself, it forwards. That distinction changes the whole design: get the identity resolution right and every downstream destination inherits it.
03Where should the event come from?
The Firefly reservation record. Send completed stays at total value, with manually entered reservations tagged by source.
04How do I know it worked?
Segment's debugger shows events arriving and which destinations accepted them. Arriving is not the test — check a destination you care about and confirm the event landed there with the identity intact, then reconcile against your own records.
