Pinterest pins accept media from any URL
- Scheduling a Pinterest pin with an image on your own domain or an external link (for example a Canva export URL) now works. Pinterest fetches image sources itself and rejects domains that disallow saving, so we copy your file into your SocialClaw media library at schedule time and publish the pin from there.
- This is the same at-schedule-time media copy that TikTok already uses, extended to Pinterest, and it happens once per file even when the same image is fanned out across several boards.
- If the URL cannot be downloaded, scheduling fails immediately with media_ingest_unreachable instead of the pin failing later at Pinterest.
