Problem

No API means voice stays siloed from your product

Fintech apps want to trigger KYC reminder calls from a backend job. Marketplaces want delivery confirmation on shipment scan. Without APIs, teams export CSVs manually — slow and error-prone.

Today

How teams integrate voice today

  1. 1Ops uploads CSVs through a dashboard — engineering not involved.
  2. 2Custom dialer integrations require opaque vendor SDKs.
  3. 3No programmatic access to transcripts or dispositions.
  4. 4Sandbox environments missing — test in production dangerously.

With SvaraCall

How SvaraCall REST API works

  1. 1Generate API keys with scoped permissions — read, write, admin.
  2. 2POST /calls to enqueue single or batch outbound with script ID.
  3. 3GET /calls/{id} for status, transcript, recording, disposition.
  4. 4Manage DNC, lists, and campaigns programmatically from your backend.

  2. Step 2

    Enqueue test call

    POST a single call to your mobile with a sandbox script ID.

  3. Step 3

    Poll or webhook

    Fetch outcome via GET or subscribe to call.ended webhooks.

  4. Step 4

REST API FAQs

Is there an OpenAPI specification?
Yes. Full OpenAPI 3 spec with examples ships on pilot — covers calls, campaigns, lists, and DNC.
Can we trigger single ad-hoc calls via API?
Yes. POST /calls with contact payload and script ID — ideal for app-triggered reminders.
How are API keys secured?
Rotate keys anytime; enterprise adds IP allowlisting and separate read-only keys.
Where does API traffic terminate?
India-region endpoints for low latency; data residency aligns with AWS Mumbai storage.
