> API changes, newest first.

## 21 October 2026: TikTok support

TikTok is officially supported in the shared inbox. The assistant can send approved JPEG/PNG images and separate text replies under TikTok’s native limits. See [Channels and message types](https://docs.sonecentral.com/en/kanallar.md). The developer API remains `/api/v1`; application release v20 does not change that base URL.

## Versioning

The URL includes the version: `https://pb.sonecentral.com/api/v1`. Changes within this version are backward compatible: new endpoints, optional request fields, response fields and error codes. Clients should ignore unknown fields.

Removing a field or changing its meaning requires a new version such as `/api/v2`, announced in advance.

## October 21, 2026: compatibility fixes

- Concurrent first messages with the same message identity return `409 conversation_busy` for the second request, rather than creating another conversation and reply.
- Responses text parts separate messages in the same turn with two newlines.
- Conversation state and message lists include `reply_pending`. Keep reading delayed assistant replies after a conversation is returned to the assistant.
- Vercel AI SDK's `finish` metadata includes `messageIds` to deduplicate streamed and polled messages. The chat widget examples use them.

## October 19, 2026: v1

Initial release.
