srstomp API Integration
Build robust, type-safe API clients from specs and documentation.
Key Principles
- Type everything — Runtime-validated types for all requests and responses
- Fail explicitly — No silent failures; throw typed errors with context
- Auth is first-class — Handle auth in the client layer, not scattered in calls
- Retry intelligently — Only idempotent methods, only transient failures, with backoff
- Isolate the boundary — Transform API shapes at the integration layer, not in app code
When NOT to Use
- Designing your own APIs — Use
api-designfor building endpoints others will consume - Writing API test suites — Use
testing-strategyfor test architecture, contract tests, mocking - Building SDKs for your API — Use
sdk-developmentfor packaging your own API as a client library
Quick Start Checklist
- Obtain API credentials and locate documentation (spec, docs, or examples)
- Analyze inputs: extract base URL, auth scheme, endpoints, error formats
- Choose architecture: typed wrapper (1-5 endpoints), service class (5-20), or generated client (20+)
- Implement types, client, auth handling, and error classification
- Add retry logic for transient failures and rate limit handling
- Write tests with mocked responses and error scenarios
