API Integration
Clean, secure connections to third-party services — built with proper auth, validation, retries, and resilient error handling.
Reliable integrations that fail gracefully
I connect your site to services like Stripe, Google Maps, email/SMS providers, CRMs, and authentication platforms. Integrations are designed for stability: credentials stay out of code, requests are validated, rate limits are respected, and webhooks are verified and idempotent.
The result is a feature that’s fast, trustworthy, and easy to hand off.
What’s Included
Auth & Credentials
OAuth2/API keys, secure storage via environment variables, scoped permissions.
Validation & Retries
Schema checks, safe parsing, retry with backoff, and circuit-breaker patterns.
Webhooks & Idempotency
Signature verification (HMAC/etc.), replay protection, and duplicate-safe writes.
Logging & Errors
Structured logs, clear error surfaces, and helpful failure states for users.
Performance
Async where appropriate, caching, timeout guards, and minimal frontend impact.
Documentation
Env examples, config notes, and step-by-step test instructions for handoff.
Technical Approach
- Credentials via environment variables or host secrets — never hard-coded.
- Request/response schema validation; strict type checks and safe fallbacks.
- Timeouts, retries with exponential backoff, and circuit-breaker safeguards.
- Webhook verification (signatures, timestamps) and idempotent processing.
- Graceful error states, structured logging, and clear user messaging.
- Caching and rate-limit awareness to reduce load and avoid throttling.
- Minimal JS on the frontend; server-side integration where possible.
Common Integrations
Payments & Billing
Stripe Checkout/Elements, webhooks for fulfillment, receipts, and subscription events.
Lead Capture & CRM
Validated forms to email/SMS or CRM; spam controls and deliverability checks.
Maps & Location
Embeds and geocoding with quota/rate-limit handling and graceful timeouts.
Authentication
OAuth login flows, token refresh, role-aware behavior, and secure redirects.
Integrate with Confidence
Share the services you need to connect — I’ll scope a stable, secure integration and hand it off cleanly.
