FunnelFlux Billing Service API

FunnelFlux Billing Service API - manages subscriptions, usage, addons, and custom domain lifecycle.

This service orchestrates across:

• Chargebee: Subscription and billing management
• Ledger: Domain registry (source of truth for ownership)
• Cloudflare: Custom hostname creation/SSL provisioning

Domain Management Architecture

Domains are stored in Ledger as the source of truth. Cloudflare status is fetched on-demand via the RefreshDomain endpoint (not on every list call).

List Domains: Returns only Ledger data (fast, no Cloudflare calls) Refresh Domain: Fetches fresh Cloudflare status + runs redirect check, updates Ledger Create Domain: Registers in Ledger + creates Cloudflare custom hostname + updates billing Delete Domain: Removes from Cloudflare + Ledger + updates billing
