Every pin needs media and a board
Pinterest rejects pins without an image/video or without a board_id. Forgetting either at publish time means the pin never leaves your draft folder.

Publish to Pinterest automatically
Pinterest is a search engine that happens to look like social media. Content Drifter generates pin descriptions, requires image or video on every pin, lets you pick the target board, and auto-publishes on Pro.
3 reasons publishing to Pinterest manually is broken
Image size failures are cryptic
Pinterest's API docs mention 32 MB but server-side processing often fails above ~8 MB. Oversize pins return generic "image processing failed" errors.
SEO descriptions need structure
The first 80–120 characters act like a meta description in Pinterest search. Hashtag stuffing in descriptions no longer helps discovery.
What Content Drifter does for Pinterest
Board selection (F188)
Choose the destination board at publish time — including manual board ID entry when Pinterest's API requires it for Business accounts.
8 MB image ceiling
Validation and auto-compress align with Pinterest's practical limit so pins do not fail downstream processing.
2:3 aspect guidance
Platform rules recommend 1000×1500 (2:3) vertical pins. Final Review surfaces aspect-ratio warnings before schedule.
Pro plan publishing
Pinterest auto-publishing is on Pro with LinkedIn, Bluesky, and YouTube. Business account required for OAuth.
Platform specs we handle
Every limit below comes from our platform-rules source of truth — the same validator the publish pipeline uses before dispatch.
- 800 character limit (content + hashtags combined)
- Up to 5 hashtags recommended
- Up to 1 image per post (jpeg, png, ≤8 MB each)
- Video: mp4, mov up to 2 GB, max 900s
- Image or video required on every post
- Aspect ratio 0.40–1.91 (e.g. 2:3 pins, 4:5 feed)
- Every pin requires an image or video AND a board_id. Pin titles are auto-generated from the first 100 chars of content; descriptions cap at 800.

Frequently asked questions
How do I publish to Pinterest automatically?
On Pro, connect Pinterest (Business account) via OAuth, attach an image or video, select your board, and schedule or publish. Descriptions cap at 800 characters.
Is Pinterest auto-posting allowed?
Yes — Pinterest provides official API access for authorized partners. Content Drifter uses OAuth through our publishing adapter.
Why do I need to pick a board?
Every Pinterest pin requires a board_id. Content Drifter prompts for board selection at publish time so API calls succeed on the first attempt.
Can I schedule Pinterest video pins?
Yes — MP4/MOV video up to 2 GB and 15 minutes is supported per PLATFORM_RULES, with the same board and media requirements as image pins.
What plan includes Pinterest auto-publishing?
