Web App + Automation Pipeline
How we built a headless automated booking sync system for a local rental fleet
Ride Crew is a Columbia, SC based premium vehicle rental fleet. They operate across both private direct bookings and a third-party peer-to-peer rental platform, but that platform locks its API, making calendar sync impossible out of the box. Every confirmation email had to be manually entered. One missed email meant a double-booked car. We fixed that, and added a direct booking channel on top.
The Problem
- No direct booking channel. Customers had to go through a third-party P2P platform even when they found Ride Crew first
- Every platform confirmation email required a manual calendar entry; a missed email meant a double-booking
- Two booking streams (direct calls + P2P platform) with no unified calendar; conflicts were a constant risk
- Generic Carrd.co template: no brand presence, no conversion path, no ownership of the customer relationship
What We Built
- Direct Booking EngineCustomers can now book privately through the site. No third-party platform required, no fees on those transactions
- Platform Email ParserSince the P2P platform locks its API, we intercept their confirmation emails, extract the booking data, and auto-block the calendar. Zero manual entry
- Unified Fleet CalendarBoth direct and platform bookings feed into one live calendar automatically. One source of truth, no conflicts
- Custom Branded Web AppReact storefront built for conversion and direct customer ownership: fast, on-brand, reservation-ready
The MaD Avenue Approach
When the platform does not open the door, we find another entrance.
Peer-to-peer rental platforms intentionally limit third-party integrations, which is understandable from a security and business perspective. Most agencies see that limitation and stop there. We look for legitimate integration points that are already available: what data is the platform already sending the client? In this case: confirmation emails. Every booking the platform processes sends a structured notification to the fleet owner. We built a parser that reads those emails the moment they land, extracts vehicle, dates, and renter info, and syncs the fleet calendar automatically. We found a legitimate integration point most agencies miss.
This is how we approach every integration challenge: not by bypassing security, but by working with what the platform already exposes to the client. The constraint becomes the brief. The legitimate integration point becomes the feature. And our clients end up with custom infrastructure that fits their workflow without breaking platform rules.

Under the Hood
Two booking channels. One calendar. Zero manual work.
The P2P platform doesn't expose an API. So we built around it.
// Channel 1: direct booking via site
on("direct.booking.submitted", async (req) => {
const booking = await parseDirectRequest(req)
await calendar.block(booking.vehicle, booking.dates)
});
// Channel 2: P2P platform (no API, parse email instead)
on("email.received", async (msg) => {
if (!isPlatformConfirmation(msg)) return
const booking = await platform.parseEmail(msg)
await calendar.block(booking.vehicle, booking.dates)
});
// ■ 0 double-bookings since launch
Direct bookings via the site
Customers can book privately through ridecrew.rentals. The form submits, the calendar blocks, and a confirmation fires. No third-party platform involved.
The platform workaround
The P2P platform doesn't allow third-party API access. So when their confirmation email arrives, our parser reads it, extracts the vehicle and dates, and auto-blocks the shared calendar.
One unified calendar
Both channels write to the same fleet calendar in real time. There's no gap window where a double-booking can sneak through.
Zero manual entries
What used to be: owner reads email → opens calendar → manually enters booking. Now: email arrives → calendar blocks automatically. Every time.
The Transformation
From generic template to conversion machine
Generic Carrd template. No brand identity, no booking engine, no direct customer ownership.
Custom React storefront. Direct booking engine, branded experience, unified fleet calendar with automated sync.
