A REST API for your entire voice stack.
We're building a full REST API for numbers, calls, billing, the AI voice agent, and the auto dialer — so you can manage everything programmatically instead of clicking through a dashboard. It's in active development and not public yet. Join the early-access list to be first in line when it opens.
What's planned
Numbers
Search, provision, and configure virtual numbers programmatically.
Calls & CDRs
Originate calls, fetch call detail records, and stream call events.
AI Voice Agent
Configure agent behavior, retrieve transcripts and summaries.
Auto Dialer
Create campaigns, upload contact lists, and pull live results.
Billing
Read balances and transactions; manage top-ups.
Webhooks
Real-time events for calls, campaigns, and payments.
Get early access
We'll email you when the API and docs are ready for developers.
Developer questions
Is the TelzLink API available today?
The API is in active development. It isn't publicly available yet, and we don't want to advertise endpoints before they're stable and documented. Join the early-access list and we'll notify you as soon as developer access opens.
What will authentication look like?
Standard API-key authentication over HTTPS, with keys managed from your account. We'll publish full authentication docs alongside the public API launch.
Can I integrate my PBX or dialer without the API?
Yes — SIP trunking and virtual numbers work today over standard SIP with any compliant PBX, no API required. The API is specifically for programmatic account, number, and campaign management.
Will there be SDKs?
We're planning SDKs for common languages after the core REST API stabilizes. Early-access signups will hear about SDK availability first.
