For uploading a file directly from your machine instead of fetching a URL, use POST /posts/{post}/media.

​
Path parameters

​
post
string
required
The UUID of the post to attach media to.

​
Request

​
urls
array
required
Public HTTP/HTTPS URLs of images or videos. Max 10 URLs per call. Size caps are enforced per type (10 MB for images, 1 GB for videos).Allowed MIME types:
  • Images: image/jpeg, image/png, image/gif, image/webp
  • Videos: video/mp4, video/quicktime (MOV)
URLs are downloaded server-side and stored as Media records on the workspace.

​
Behaviour

  • The post must belong to the caller’s current workspace; otherwise the response is 404.
  • Allowed media types are intersected with the platforms enabled on the post. If an enabled platform doesn’t support the file type (e.g. video on a platform that’s image-only), that file is rejected and listed in failed_urls.
  • Successful attachments are appended to the post’s media[] array.

​
Response

Returns an object with three fields:
​
post
object
The updated post — same shape as GET /posts/{post}, with newly-attached items now in the media[] array.
​
attached_count
integer
Number of URLs that were successfully downloaded and attached.
​
failed_urls
array
URLs that were rejected (unreachable, wrong MIME type, too large, or not allowed by any enabled platform). Each entry is the original URL string.
