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.
Need More Than Comments?
Add publishing and scheduling to the same connected Threads workflow.
Ship Threads Comments in Any Stack
Whether your product is a Node app, a no-code workflow, or an AI agent, the same PostPeer API can power the publishing workflow.
Dev Stack
Typed SDKs and predictable REST APIs let you integrate PostPeer into the stack your application already uses.
- Node.js SDK
- Python SDK
- REST + cURL
- TypeScript-first types
