Signed upload links used by AI agents (via MCP) are single-use and expire after **15 minutes** by default. ## Platform content types and media requirements Each platform supports different content formats with specific media requirements — this table is the reference. There is **no** `linkedin_carousel`, `linkedin_page_carousel`, or `instagram_carousel` content type on posts. Multi-image Instagram posts use `instagram_feed`. LinkedIn multi-image / PDF posts use `linkedin_post` / `linkedin_page_post` (format is inferred from the attached media; optional `meta.document_title` for PDFs). ### LinkedIn / LinkedIn Page | Content type | Media | Max files | Notes | | -------------------------------------- | -------- | ------------------------------------- | --------------------------------------------------------------------------------- | | `linkedin_post` / `linkedin_page_post` | Optional | Up to 10 images, or 1 video, or 1 PDF | Images/videos/documents cannot be mixed.

The order you set is the order they'll appear on the social platform — important for carousels and multi-image posts. ## FAQ **10 MB** per image, **1 GB** per video, **100 MB** per PDF. Each post stores its own media records. To reuse the same image, upload it again or copy from the asset library. The media records are removed along with the post. Wanhap uploads media to social platforms as-is. Each platform applies its own compression and resizing rules afterwards.
