Function createThreadsPost

createThreadsPost(
    token: string,
    input: string | ThreadsPostInput,
    replyToID?: string,
): Promise<string | null>
Publishes to Threads — text, image, video or carousel, chosen from the media you pass. Creates the container, waits for Threads to finish processing it, then publishes.

Media URLs must be publicly reachable — Threads downloads them server-side.
Parameters
- token: string
  Threads access token.
- input: string | ThreadsPostInput
  Post text, or a ThreadsPostInput for media, replies and reply controls.
- OptionalreplyToID: string
  Parent post id, to make this post a reply. Also settable on input.
Returns Promise<string | null>
Promise of the published post id, or null if any step failed (the API's error is logged).
Example
```
import { createThreadsPost, MetaMediaType } from "naystack/socials";

await createThreadsPost(accessToken, "Hello from Naystack!");

await createThreadsPost(accessToken, {
  text: "Campaign recap",
  media: [
    { url: "https://cdn.example.com/1.jpg", type: MetaMediaType.Photo },
    { url: "https://cdn.example.com/2.mp4", type: MetaMediaType.Video },
  ],
