Ship voice integrations faster with typed SDKs

SvaraCall SDKs wrap the REST API with idiomatic Node.js and Python clients — retries, typing, and webhook verification built in so your team focuses on product logic.

Problem

Raw HTTP integrations slow every sprint

Engineers reimplement auth, retries, and pagination for each voice feature. Bugs hide in hand-rolled JSON parsing. Indian product teams need to ship calling in days, not quarters.

How teams integrate without SDKs

  1. 1Copy-paste curl examples into services with no typing.
  2. 2Reimplement HMAC verification differently in each microservice.
  3. 3Miss API version changes until production breaks.
  4. 4No shared error handling — transient 503s lose calls.

With SvaraCall

How SvaraCall SDKs work

  1. 1Install @svaracall/node or svaracall-python from registry.
  2. 2Initialize client with API key — methods map 1:1 to REST resources.
  3. 3Use built-in retries and idempotency keys on call.create.
  4. 4Verify webhooks with one-line signature check helpers.

Why SDKs beat raw REST

  • Faster shipping

    First call enqueued in under an hour from npm or pip install.

  • Fewer bugs

    Typed requests catch field errors at compile time.

  • Consistent security

    Webhook verification matches docs — no drift across services.

  • Version clarity

    Semver SDK releases track API changes with migration notes.

Get started with the SDK

  1. Step 1

    Install package

    npm install @svaracall/node or pip install svaracall — use sandbox key.

  2. Step 2

    Enqueue test call

    Five lines to create a call — run against your mobile number.

  3. Step 3

    Handle webhook

    Use verifySignature helper in your Express or FastAPI route.

  4. Step 4

    Promote to prod

    Swap API key; enable rate limits; monitor via analytics.

SDK FAQs

Which languages have official SDKs?
Node.js (TypeScript) and Python today. Community wrappers for Go and Java on roadmap — REST API always available.
Do SDKs support async operations?
Yes. Promise-based Node client and async Python client for modern frameworks.
How are SDK versions tied to API versions?
Semver SDK releases document compatible API versions — breaking changes bump major.
Can we verify webhooks with the SDK?
Yes. verifyWebhookSignature helpers ship in both packages with test vectors in docs.
