Native voice notes. Any platform.
One API call.
Svara is a REST API that sends native voice notes on LinkedIn, Telegram, WhatsApp, and 6 more platforms. No SDKs, no platform-specific code. One endpoint, native delivery, every time.
What is Svara?
Voice notes get 3x the reply rate of text. But sending them programmatically means dealing with platform-specific formats, upload flows, and authentication. Svara handles all of it with a single POST request.
curl -X POST https://svarapi.io/api/v1/send \
-H "Authorization: Bearer sk_live_..." \
-H "Content-Type: application/json" \
-d '{
