Everything You Need for TikTok Messaging

Read and reply to direct messages without wrestling the TikTok API. List conversations, load history, and send replies from one endpoint.

List Conversations

Fetch DM conversations for a connected TikTok account with each participant name, username, and profile picture, plus the most recent message and updated time.

Read Message History

Load the messages in a conversation, paginated, each with the sender and a timestamp. Rebuild the full thread on your side.

Send Replies

Reply to a recipient with one call. The response returns the sent message ID so you can track delivery and reconcile it against your inbox.

OAuth Handled

Your users connect their TikTok account through PostPeer's OAuth flow. No developer app, no token juggling, and no rate-limit handling on your side.

Build Your Own Inbox

Everything the PostPeer dashboard inbox uses is available through the API, so you can build a branded support inbox or route DMs into your own tools.

One Endpoint Across Platforms

The TikTok Messages surface uses the same `/v1/messages` request and response shape as every other PostPeer messaging endpoint. Add it without a new integration.
