Upload media from file

Upload one image or video with multipart/form-data. Fields:
  • workspace_id (required) — workspace that will own the file
  • file (required) — the binary upload
  • folder_id (optional) — media library folder in that workspace
The API reads the MIME type from the file (you do not send mimeType). Allowed types are the same as in the app (JPEG, PNG, GIF, WebP, MP4, MOV, etc.). Maximum size per request is 500MB (same as the in-app standard upload). Response 201: { "media": { "id", "url", "mime_type", ... } } — use media.id in Create post content[].media. Do not use this endpoint for URL import — use Import from URL.
