Integrate from Any Stack — Without Pretending an Unpublished SDK Exists
phoneveriflo is 100% REST-first. Integrate immediately with copy-ready, production-grade snippets across 8 backend languages, or track the release status of our official typed client libraries.
Every environment with HTTPS capabilities can submit asynchronous jobs and verify signed webhooks.
Multi-Language Integration Workbench
Select your language and operation to get battle-tested, copy-ready client code with error handling, idempotency, and type safety.
Official SDK Package Publication Status
We never advertise unpublished SDK packages as installed until they exist in public package registries with semantic versioning and continuous integration test coverage.

Why REST-First?
You don't have to wait for SDK updates or manage dependency lockfiles. Our stable JSON contracts and standard HTTPS endpoints are ready in minutes from any language.
What Official SDKs Will Add
When published, official packages provide typed request builders, automatic UUID idempotency middleware, built-in webhook signature validators, and transparent connection pooling.
Version Compatibility
Every API change is backwards-compatible. Non-breaking additive fields are introduced without breaking changes, and migrations are documented in the Changelog.
Production Architecture Guidelines
Follow these battle-tested patterns to ensure maximum reliability, security, and throughput.
1. Server-Side Key Isolation
Never expose secret API keys (pv_live_...) in frontend browser applications, mobile bundles, or public repositories. All verification requests must originate from your secure backend servers or cloud workers.
2. Idempotency on Every Write
Always supply a unique Idempotency-Key header (such as a UUID v4) when calling POST /api/v1/jobs. If a network blip occurs during job submission, retrying with the same key returns the existing job without double-billing.
3. Webhook Replay Attack Defense
Always verify the timestamp inside the X-Veriflo-Signature header. Reject any webhook event older than 300 seconds (5 minutes) to prevent replay attacks, and compare signatures using constant-time algorithms.
4. Rate Limit Backoff & Jitter
When consuming API endpoints at high throughput, respect the Retry-After response header on HTTP 429 status codes. Implement exponential backoff with full jitter to avoid thundering herds.
Libraries & Integration FAQs
Can I integrate phoneveriflo without an official SDK package?
Yes. phoneveriflo is 100% REST-first. You can use standard HTTP client libraries (such as fetch in TypeScript/Node, httpx or requests in Python, net/http in Go, or HttpClient in C#/Java) using our copy-ready snippets above.
Where should I store and manage API keys?
Store your API keys as server-side environment variables (e.g. PHONEVERIFLO_API_KEY) or in a secure secret manager (such as AWS Secrets Manager, Vault, or Doppler). Never bundle keys into frontend React/Vue code.
How can I test webhooks locally during development?
Use a tunneling tool like ngrok or Cloudflare Tunnels to route webhook events to your local development machine (e.g. https://abc.ngrok-free.app/webhooks/phoneveriflo). Make sure your test receiver validates the HMAC signature.
When will official package manager SDKs be published?
Our Node.js / TypeScript SDK is currently in Beta and targeted for Q3 2026. Python, Go, PHP, Ruby, and .NET packages will follow in Q3/Q4 2026. Check the Changelog for release announcements.
