eCartApi
While building a single standardized schema wrapper for 2-3 carts takes days, maintaining auth, webhooks, and breaking API updates across 30+ platforms requires dedicated engineering bandwidth. You aren't paying for complex algorithms; you are paying for platform adapter maintenance and rate limit handling.
you can rebuild
- Unified JSON schema mapping for product and order payloads
- Developer dashboard for API credential and token management
- Webhook relay and event standardizing across platforms
- Basic REST proxy middleware between application and cart endpoints
- Request and response logging with audit trails
what you lose
- Pre-built connectors and OAuth flows for 30+ ecommerce platforms
- Automatic maintenance for third-party API version deprecations and breaking changes
- Built-in rate limiting queues and platform throttling management
- Unified error handling and standardized response normalization
- Managed infrastructure for secure third-party store token storage
real moats
- Massive ongoing engineering footprint to maintain 30+ cart API adapters
- High integration lock-in once app backend relies on unified endpoints
- Platform version deprecation tracking and automated fallback handling
