REST APIs
Use predictable endpoints, signed requests, and API keys built for production.
WAStack's REST API is designed for developers who value simplicity, predictability, and reliability. Every endpoint follows consistent patterns: RESTful URL structures, JSON request/response bodies, proper HTTP methods, and standard status codes.
Authentication uses Bearer tokens via the Authorization header. API keys are scoped to specific sessions and can be rotated without downtime. Each key has configurable permissions to limit access to read, write, or admin operations.
The API returns detailed error responses with machine-readable error codes, human-readable messages, and suggested fixes. Pagination uses cursor-based patterns for consistent performance at scale.
Documentation includes interactive API explorer, copy-paste code examples in multiple languages, request/response schemas, and real-time API status information.
