Mileage Tracker by Driversnote — API integration services

Deliverables checklist

• OpenAPI / Swagger specification for every exposed endpoint
• Protocol & authentication report (OAuth, refresh, session tokens, mobile-side request signing)
• Runnable Python and Node.js source for trip listing, logbook export, and team approval polling
• Connector adapters for QuickBooks Online, Xero, SAP Concur, NetSuite, Wave, and custom ERPs
• Postman collection, integration tests, and OpenAPI-driven mocks
• Compliance notes covering IRS Rev. Proc. 2019-46, GDPR, and EU/UK data-residency considerations

Two engagement models

You can pick the model that suits your project:

• Source code delivery from $300 — we hand over runnable API source code and complete documentation. You pay only after delivery once the integration meets your acceptance tests.
• Pay-per-call hosted API — call our managed endpoints with a key, pay per request. Suitable for variable workloads or proof-of-concept work where infra cost should track usage.

Scenario 1: Reimbursement sync to payroll

An SMB pays drivers monthly mileage reimbursement. Each night a job calls /v1/trips?since=…&classification=business, multiplies distance_km by the IRS 2025 rate of 70 cents per mile (or a custom per-vehicle rate), and posts a reimbursement line to the payroll provider. Maps to the OpenFinance pattern of account-data → calculation engine → payment instruction.

Scenario 2: Quarterly tax substantiation export

A self-employed contractor exports a full IRS-compliant logbook every quarter. We trigger /v1/logbook/export with format=xlsx, archive the file with a SHA-256 hash, and post the metadata (driver, period, file hash) to the customer's accounting bucket. This satisfies Rev. Proc. 2019-46 substantiation requirements without manual download steps.

Scenario 3: Fleet anomaly & fraud detection

For a delivery fleet, business trips outside work hours, distance spikes vs. odometer readings, or trips logged without an iBeacon pairing are routed to an anomaly queue. Trip JSON, vehicle metadata, and beacon pairings are joined in a warehouse and scored — a typical OpenData analytics pipeline applied to mileage rather than transactions.

Scenario 4: Concur / NetSuite expense feed

Each approved team submission is converted into an expense report in SAP Concur or NetSuite via webhook. The webhook payload contains the submission ID, driver, period, classified totals, and a link to the underlying logbook PDF, which is uploaded as the receipt. Approvals already done in Driversnote do not have to be repeated.

Scenario 5: Cross-border field-team reporting

For multinational teams the same drivers may log miles under IRS rules in the US and HMRC AMAP rates in the UK. We segment trips by workplace country, apply the correct per-mile rate, convert currency at month-end FX, and deliver a unified PDF — useful for audit-friendly cross-border field-team reporting.

Compliance & privacy

Mileage is sensitive location data, so every integration we ship treats it that way. Reports are designed to satisfy IRS standard mileage rate rules and the substantiation guidance in Notice 2025-5 and Rev. Proc. 2019-46. For UK customers, exports follow HMRC AMAP rates; for EU customers, the pipeline is GDPR-aligned with explicit consent capture, configurable retention, and right-to-erasure flows. We also note that Driversnote's own privacy promise — "we never sell data" — should not be undermined by integrations, so consent is logged on every export job.

Data flow / architecture

• Client app — Driversnote iOS / Android / web app collects GPS and classifies trips.
• Ingestion API — our partner-side gateway receives authorized OAuth-bearer requests, validates scope, rate-limits.
• Storage & rate engine — trip records normalized; IRS / HMRC / custom per-mile rates applied.
• Export & webhook layer — JSON / Excel / PDF artifacts plus webhook events delivered to the customer ERP, accounting, or analytics warehouse.

Three to four nodes is enough to model the typical mileage OpenData pipeline; we keep PII at the edge and forward only what the destination system actually needs.

Engagement workflow

1. Scope confirmation: which Driversnote data, which destination system (ERP, accounting, payroll, warehouse), regions, rate sources.
2. Protocol analysis and API design (2–5 business days, complexity-dependent).
3. Build and internal validation against a test Driversnote account (3–8 business days).
4. Documentation, sample exports, Postman collection, integration tests (1–2 business days).
5. Typical first delivery: 5–15 business days. Team-approval webhooks and ERP-side certification may extend timelines.
