Everything You Need for Threads Comments

Read and reply to Threads replies without managing the Threads API directly. One endpoint, same shape as your other comment integrations.

List Replies

Fetch the replies on a Threads post with author, text, and timestamp. Threads calls comments "replies," and this returns them in the same shape as Instagram and Facebook comments.

Reply to Threads

Respond to a post or to an existing reply with one call. Pass the reply ID and your text.

Create Top-Level Threads

Post a new top-level thread by passing a postId. Useful for scheduled community prompts or reply-and-continue threads.

Unified Comments Endpoint

Same `/v1/comments` endpoint and response shape as Instagram and Facebook. Add Threads without writing another integration.

Works on Existing Posts

Read and reply to replies on any post on the connected Threads account, not only ones published through PostPeer.

No Meta App Review

PostPeer is approved for `threads_manage_replies` and handles the OAuth flow for you.
