Platforms
Publish text, images, image carousels and videos to Threads with reply controls; limits, options and credit cost.
Sandbox
In the sandbox these options are validated exactly as in production, but nothing is posted: each target gets a simulated result and a preview page. The outcomes described here (for example carousels and reply controls) are production behaviour and apply once live platform access opens.
Use "platform": "threads".
platformSpecificData| Field | Type | Description |
|---|---|---|
replyControl | string | Who can reply: everyone (default), accounts_you_follow or mentioned_only. |
altText | string[] | Alt text for each image, in the same order as mediaItems. |
