Fleet managers using WEX cards without software integration are flying blind transactions get logged, but nobody can tell if they were legitimate. Industry data shows 19–22% of fleet fuel spend is lost to fraud and misuse every year. FleetRabbit's WEX integration auto-matches every transaction to GPS location, flags anomalies instantly, and eliminates manual reconciliation entirely.

FleetRabbit now connects to WEX fleet cards via the WEX API — pulling Level III transaction data including driver ID, fuel grade, cost per gallon, and location. Every purchase is cross-referenced against your vehicle's live GPS position in real time. Anomalies are flagged immediately, not days later. Setup takes under 10 minutes with no hardware and no IT team required.
Why WEX Data Alone Leaves You Exposed
WEX is a great fuel card — accepted at 95% of US stations, trusted by 600,000+ businesses. But here's what nobody says out loud: WEX tells you what was purchased. It does not tell you if it was legitimate.
Without connecting WEX transactions to your vehicle's GPS, odometer, and driver assignment, you can't confirm whether the fuel was actually pumped into your truck, whether the vehicle was even at that station, or whether someone used a company card on a personal vehicle. That gap is exactly where fraud lives — and it's where fleets bleed money quietly, month after month.
How FleetRabbit + WEX Works — The Full Integration Flow
Once you connect your WEX account to FleetRabbit, the entire transaction lifecycle — from pump to report — runs automatically. Here's exactly what happens at every step.
Driver uses their WEX card at any of 180,000+ US fuel locations. Transaction data — including driver ID, fuel grade, cost per gallon, gallons purchased, and station location — is captured via WEX Level III data. No change to the driver's experience whatsoever.
FleetRabbit's WEX fleet card API connection syncs the transaction in real time — no manual imports, no CSV uploads, no scheduled batch pulls. The moment WEX processes the transaction, FleetRabbit has it. Data is matched to your vehicle list and driver roster automatically.
FleetRabbit cross-references the station's location against the vehicle's live GPS position at the time of the transaction. If the vehicle was within acceptable proximity — the transaction clears automatically. If the GPS shows the truck was somewhere else — an anomaly flag is raised immediately and you get an alert.
Beyond GPS matching, FleetRabbit runs six additional fraud checks on every transaction: over-tank volume (gallons exceed tank capacity), off-hours purchase (outside approved operating times), velocity check (multiple transactions in a short window), fuel type mismatch (diesel card at gas station), route deviation, and duplicate transaction detection.
Clean, verified transactions are automatically filed against the vehicle's cost record — no manual entry. Per-vehicle fuel cost, per-driver fuel usage, and per-route consumption are updated in real time. Month-end reconciliation becomes a 3-minute review instead of a 3-day project.
Every WEX transaction — with GPS verification, driver ID, anomaly status, and cost allocation — is stored with a complete audit trail. Pull a full fuel spend report by vehicle, driver, depot, or date range in under 60 seconds. Available any time for accounting, compliance review, or insurance purposes.
What the Integration Detects — And What It Does About It
FleetRabbit's WEX fraud detection isn't a blunt alarm — it's a layered system that runs specific checks against your own fleet's data patterns. Here's what each detection layer catches and how it responds.
Every flagged transaction is surfaced in the FleetRabbit dashboard with full context — driver, vehicle, station, GPS position, amount, and the specific rule that triggered the flag. You review in one click: approve it if it was legitimate, or escalate if it wasn't. Book a demo to see WEX fraud detection running on live transaction data →
WEX Card Alone vs. WEX + FleetRabbit Integration
WEX is a powerful fuel card. But what you get from the card's own reporting versus what you get when it's connected to FleetRabbit is not even a close comparison.

Frequently Asked Questions
Yes. FleetRabbit connects to WEX fleet cards across all product lines — including WEX EFS fleet cards and WEX-branded partner cards from ExxonMobil, Shell, and Chevron. The integration uses the WEX fleet card API, which covers transaction data across the full WEX network including 180,000+ US fuel locations. If your card runs on WEX's backend, it connects to FleetRabbit. Card setup, driver assignment, and vehicle mapping are all auto-imported from your WEX account during the initial connection.
Detection runs in real time as transactions sync from WEX. If a purchase doesn't match the vehicle's GPS location, exceeds tank capacity, occurs outside approved hours, or triggers any of FleetRabbit's six anomaly checks — you receive an alert immediately. This is the critical difference from WEX's own reporting, which is retrospective. FleetRabbit's detection is live, so you can act on suspicious activity before more transactions occur — not a month later when you're reviewing a statement.
FleetRabbit does not replace WEX — it connects to it. Your drivers continue using WEX cards exactly as before, at the same stations, with the same purchase process. FleetRabbit reads your WEX transaction data via API and enriches it with GPS verification, anomaly detection, and automated reporting. You keep your WEX account, all rebates (up to 15¢/gallon), and full network access — while gaining the intelligence layer that WEX alone doesn't provide.

Under 10 minutes for most fleets. The process is: (1) enter your WEX account credentials inside FleetRabbit — 2 minutes; (2) review and confirm the auto-imported vehicle and driver mapping from WEX — 3 minutes; (3) set your anomaly alert thresholds (defaults are pre-configured, so you can skip this initially) — 3 minutes. After that, WEX data starts flowing automatically. No IT team, no hardware, no scheduled maintenance. Transactions begin syncing and getting GPS-verified from that moment.

WEX integration is included in FleetRabbit's base platform at no extra charge. FleetRabbit is priced at $3 per vehicle per month — which includes WEX fuel card integration, GPS tracking, automated reconciliation, real-time fraud detection, maintenance records, compliance tracking, and fleet analytics. There are no per-transaction fees, no integration surcharges, and no setup costs. You can also start completely free with up to 3 vehicles — no credit card required — to see the WEX integration working with your actual transaction data before committing to a paid plan.
When FleetRabbit flags a WEX transaction, you receive an immediate alert with full context: which vehicle, which driver, which station, what was purchased, the GPS location of the vehicle vs. the station, and which specific rule was triggered. From the alert, you can: (1) approve the transaction if it was legitimate, (2) mark it as fraud and escalate to your WEX account for investigation, or (3) set a rule to automatically flag similar future transactions. All flagged transactions are stored with their full audit trail regardless of outcome, giving you a complete history of anomalies for any compliance or insurance review.
