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 includes Pinterest on every plan including the free one.
Publish to 9 platforms with one workflow
- X
- Threads
- YouTube
- Bluesky
- TikTok
- AI voice match
- Gold-slot scheduling
- Branded image generation
- Closed-loop analytics
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 to 120 characters act like a meta description in Pinterest search. Hashtag stuffing in descriptions no longer helps discovery.
What changes once Pinterest runs on autopilot
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.
Pinterest on every plan
Pinterest is available on every plan including Free; a Pinterest business account is the only requirement for OAuth. Hands-off auto-publishing starts on Starter ($19/mo).
The Pinterest rules we enforce before publish
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 to 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.
Publishing to Pinterest, start to finish
- 1
Connect an account and pick a destination board
Every Pin needs a board, and that is the single most common reason a Pinterest integration fails at publish. The connection lists your boards and stores a default, so a queued Pin always has somewhere to land.
- 2
Built as a vertical Pin with a destination link
Pinterest is a discovery surface, so Pins are generated at the 2:3 ratio the feed favours and carry the destination URL and alt text. Wrong ratios get cropped in the grid, and Final Review catches that before it queues.
- 3
Published with a longer half-life in mind
Pins keep earning impressions for months rather than hours, so the schedule spreads them instead of clustering. The pipeline publishes to the chosen board and records the Pin against your analytics.
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?
Every plan. Pinterest, like all nine networks, is on the free plan; you only need a Pinterest business account for the OAuth connection. Hands-off auto-publishing of scheduled pins starts on Starter ($19/mo).
