pinterest.media.required

What it checks

media.length >= 1. Pinterest pins always carry exactly one media item — image or video.

Attach an image, or a video with a cover image URL:

image-pin.json

{
  "media": [{ "kind": "image", "mediaId": "med_…" }]
}

video-pin.json

{
  "media": [{ "kind": "video", "mediaId": "med_…" }],
  "pinterest": { "coverImageUrl": "https://cdn.example.com/cover.jpg" }
}

Single-pin-per-request still applies — see pinterest.media.single_only.
