Example projectAPI
Public API with docs and SDKs
Hypothetical. Not a client, not a result.
// The problem
A SaaS company's larger customers want to connect it to their own systems, and the internal endpoints the web app uses are undocumented and change without warning.
// What we would build
A versioned public API with keys and OAuth, a developer portal with docs and examples, SDKs in two languages, webhooks and a gateway with rate limits and monitoring, so customers can build on the product safely.
// What is in it
- A versioned REST API with keys and OAuth
- A developer portal with docs and examples
- SDKs in two languages
- Webhooks for the events customers care about
- Rate limits, monitoring and usage per customer
// Stack
- Node.js
- PostgreSQL
- OpenAPI
- API gateway
