Why Choose PostPeer

Build the social experience your users need while PostPeer handles the platform-specific complexity behind it.

One Endpoint, Every Platform

Read and moderate comments on Instagram, Facebook, and Threads through a single `/v1/comments` endpoint. Same request shape everywhere, you just switch the platform value.

List Comments and Replies

Fetch every comment on a post with author, text, timestamp, like count, and its replies. Paginate through long threads with a cursor, normalized across platforms.

Reply and Comment

Post a top-level comment on a post, or reply to an existing comment. Same endpoint, you just switch between a postId and a commentId.

Hide and Unhide

Toggle a comment between hidden and visible to moderate spam without deleting it. Available on the platforms that support it, like Instagram and Facebook.

Delete Comments

Remove a comment from your post when hiding is not enough. One call by comment ID, regardless of which platform the comment lives on.

Works on Existing Posts

Moderate comments on any post on the connected account, not only posts you published through PostPeer. No platform App Review on your side.

Manage Social Media Comments Across Supported Platforms via One API
