Threads

The Threads API for publishing posts and replies

Threads has a full publishing API, and you can use it without registering a Meta developer app. Create text, image, video, and carousel posts, fetch reply threads, and hide or delete replies through one REST endpoint. SocialAPI.ai runs the Meta app and its review process for you.

The same POST /v1/posts endpoint you already use for every other platform. SocialAPI.ai handles Threads' container creation and, for carousels, the multi-step assembly behind the scenes.

What you can do with Threads.

Supported

Comments

Read replies on your Threads posts, reply to them, fetch the full reply thread under a comment, and hide, unhide, or delete replies. Toggling comments off for a post is not supported by the Threads API.

Supported

Mentions

Delivered to your webhook endpoint in real time. Threads has no polling endpoint for mentions.

Supported

Publishing

Publish text-only, single image, single video, and carousel posts holding 2 to 20 images, videos, or a mix of both.

Supported

Webhooks

Receive real-time notifications for new replies and mentions on your Threads posts.

The official API vs one API key.

Getting access

the Meta Threads API

Register a Meta developer app, configure Threads use cases, and pass app review yourself.

With SocialAPI.ai

No Meta registration. Connect a Threads account through OAuth and publish immediately.

Publishing

the Meta Threads API

Two-step container flow: create a media container, poll its status, then publish.

With SocialAPI.ai

One POST /v1/posts call. Container creation and status polling happen behind the endpoint.

Mentions

the Meta Threads API

Requires Advanced Access approval plus the threads_manage_mentions scope and your own webhook plumbing.

With SocialAPI.ai

Mention events arrive on your configured webhook endpoint with verified signatures.

Reply moderation

the Meta Threads API

Separate endpoints and permission scopes for hide, unhide, and delete.

With SocialAPI.ai

One moderation endpoint: hide, unhide, or delete any reply.

Good to know.

Threads does not support editing a published post through the API. Delete the post and publish a new one instead.

Threads does not provide a DM API, so direct messages cannot be read or sent through any third-party integration.

Threads mentions are webhook-only: there is no polling endpoint, and Meta requires Advanced Access with the threads_manage_mentions scope.

Threads does not support toggling comments off for a post through the API.

Why developers love Threads on SocialAPI.ai

1

Multi-format publishing

Publish text-only posts, single image posts, single video posts, and carousel posts holding 2 to 20 images, videos, or a mix of the two. SocialAPI.ai handles the Threads API's container creation flow for you: a single atomic call for text, a two-step container-and-publish flow for single media, and a three-step flow for carousels. You send one request and the API handles the rest.

2

Reply-thread management

Read every reply on your Threads posts through a single paginated endpoint, reply back to engage with your audience, and fetch the full reply thread under any comment. SocialAPI.ai normalizes Threads' reply model into the same comment schema used across every other connected platform.

3

Reply moderation

Hide, unhide, or delete any reply on your Threads posts through one moderation endpoint. Threads does not support toggling comments off for an entire post, so hide, unhide, and delete are the moderation actions available.

4

Webhook-only mentions

Threads has no polling endpoint for mentions, so a webhook is the only way to track them. SocialAPI.ai verifies Meta's webhook signatures and delivers mention events to your configured endpoint in real time, alongside new-reply notifications.

5

Managed Meta app

SocialAPI.ai runs the Meta Threads App and carries the app review process on its side, so you never register your own Meta developer app. Connect a Threads account through OAuth and start publishing immediately.

Simple, honest pricing.

Reading comments, DMs, and mentions is free and unlimited on every plan. Paid plans start at $29/mo with unlimited posts and interactions. The free tier needs no credit card.
