# Schedule Threads posts and multi-part threads.

Plan Threads posts next to X and Bluesky, adjust the text for each and publish replies in order as one thread.

## What you can post to Threads

- **Post**: Up to 500 characters, with up to 20 photos and videos (video up to 5 minutes).
- **Thread**: Extra parts publish as replies, in order.

## Why teams schedule Threads with PostBoost

- **One calendar for every channel**: See Threads next to your other 14 channels and move posts when plans change.
- **One post, a version per network**: Write once, then adjust the text for Threads without copying the post.
- **Know when a post fails**: If Threads rejects a post, you see why and can retry it once it is fixed. A webhook can tell your code too.
- **Same idea, three networks**: Start from one text and keep a version for Threads, X and Bluesky, each inside its own limit.

## Connect Threads in three steps

1. **Open Accounts**: Choose Connect account, then Threads.
2. **Sign in to Threads**: Approve PostBoost. Your account appears in the composer.
3. **Write and schedule**: Write a post or a thread and pick a time.

## Post to Threads from your AI agent or your code

Ask your agent: "Post this announcement to Threads and Bluesky, shortened to fit each, at 14:00 today." (MCP tools: `count-characters`, `create-post`, `schedule-post`). Not connected yet? Ask your agent to connect Threads: it sends you a one-time sign-in link that works for 15 minutes.

API: `createPost` (https://postboost.co/docs/api/create-post/)

```bash
curl -X POST https://postboost.co/app/api/{workspaceUuid}/posts \
  -H "Authorization: Bearer YOUR_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"accounts": [12], "queue": true, "versions": [{"account_id": 0, "is_original": true, "content": [{"body": "Our API 1.8 is live."}]}]}'
```

## Good to know

- Longer text needs a thread: each part has the 500-character limit.
- Photos and videos can be mixed in one post.

## Questions about Threads

### What is the Threads character limit?

500 characters per post. For more, add parts and publish it as a thread.

### Can I post the same thread to X and Bluesky?

Yes. Add all three accounts to one post and adjust the text per network. Each network's limit is checked before publishing.

### Can I connect Threads on the Free plan?

Yes. Every plan can connect Threads. The Free plan includes 3 social accounts and 3 scheduled posts. Paid plans start at $29 a month with a 14-day free trial.

### Can my AI agent post to Threads?

Yes. Connect PostBoost to Claude, ChatGPT, Cursor or another MCP client, then ask it to write or schedule a Threads post. Posts stay drafts until you or the agent schedule them.
