Changelog

The API is versioned in its URL (/api/public/v1). Within a version we only make additive changes: new endpoints, new optional parameters, new response fields and new webhook events. Build your integration to ignore fields and event types it does not know.

The current version is 1.0.0.

1.0.0

3 October 2026

• Outbound calls now detect answering machines. Each organization chooses what happens when voicemail answers (leave a short message, hang up and retry later, or hang up); outbound calls and the outbound_call.completed webhook carry answered_by (human, machine or unknown) and voicemail_left_at. Test mode: +15125550133 reaches voicemail. See Outbound calls.
• Spam handling for inbound calls: calls carry spam and caller_name; GET /calls takes spam and status=blocked; the call.completed webhook carries spam. New blocked-caller endpoints (GET, POST, DELETE /blocked-callers) and the block_caller MCP tool.
• GET /calls and the platform MCP server now return spam on every call.

2 October 2026

• Added test mode: vk_test_ keys that work on a separate set of test data, simulated outbound calls, per-mode webhook endpoints, and a livemode field on every object and webhook delivery. See Test mode.
• Every error now returns a code, including validation_failed, unauthenticated, not_found, method_not_allowed, rate_limited and server_error.
• POST /do-not-call answers 200 with the existing entry when the number is already on the list.
• Added replying to live chats (POST /chats/{chat}/messages, scope chats:write) and closing them (POST /chats/{chat}/close).
• Added the chats:write scope.
• Added live chat webhook events: chat.started, chat.message.created, chat.lead_captured, chat.handoff_requested and chat.closed, alongside chat.handed_off.
• Test deliveries can now send a sample of a real event: POST /webhook-endpoints/{webhookEndpoint}/test with event.
• New developer docs at /docs, with Markdown versions of every page and a public docs MCP server.
