Landing Page — Phone Cases (Mexico)

Standalone FastAPI landing page for the Terex phone case business. Reads the same Supabase project as the inventory app (cxmex/inventoriorapido1), so stock and sales data stay in sync without duplication.

Run locally

python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
cp .env.example .env   # then fill in real values
uvicorn app:app --reload --port 8000

Open http://localhost:8000

Deploy (Railway)

Procfile is configured. Set the same env vars from .env.example in the Railway project.

A/B testing

The root route / randomly assigns visitors to variants A, B, or C and 302-redirects to /v/<variant>. Variant assignment + every page event is logged to landing_events.

URL params honored everywhere:

• ?wa=<phone> — WhatsApp number of the visitor (passed in by ads / WhatsApp links so we can correlate sessions)
• ?v=A|B|C — force a specific variant (overrides random assignment, useful for ad campaigns)
• ?utm_source, ?utm_campaign — standard, stored on every event

Database

Run migrations.sql in the Supabase SQL editor once. It creates:

• landing_events — page views, variant assignments, clicks, cart adds
• landing_leads — captured emails / phone numbers
• landing_carts — server-side cart state (keyed by session)

The catalog tables (inventario, inventario_modelos, inventario_estilos) are owned by the inventory app — this app reads them but does not write.
