## Threads

### Why did my multi-image Threads post fail? ("Threads only supports a single image or a video")

The Threads API accepts 1 image or video per post. Carousel posts are not supported via the API, even though the Threads app allows them when posting manually. A Threads post with multiple images fails with an error about the number of attachments.

To share multiple images, publish a thread instead: attach one image to each post in the thread (post 1 contains image 1, post 2 contains image 2, and so on). Follow the steps below.

### Post a Thread with Photos

1. Go to the [AI Agent](https://my.contouron.com/agent)
2. Click "+ Add Post" and select Threads
3. Write your first post and attach photos via "Add Media"
4. Click "+ Add to Thread" to add more posts to the thread
5. Attach photos to each thread post as needed
6. Schedule or publish

For an automated thread workflow, see: Email to Long Form Thread

For API thread posting, see: Twitter Threads (the same `additionalPosts` field works for Threads)

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.contouron.com/platforms/threads.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
