Queue Pins per board, keep the media rules straight, and plan a catalogue push on the same calendar as the rest of the networks.

Formats and rules
What PostSider publishes to Pinterest
Pins are simple until they are not. The API accepts one to five images, or one video with a cover, and it rejects almost everything else silently at first glance. These are the rules the integration checks before a Pin enters the queue.
| Pin type | Media rule | What the composer asks for |
|---|---|---|
| Standard image Pin | At least one image, up to five images | Board, image set, Pin text, destination link |
| Multi-image Pin | Up to five images, all identical in width and height | The same board and text fields, with the size check before publishing |
| Video Pin | Exactly one MP4 video plus exactly one cover image | Two attachments, nothing else, and the cover is mandatory |
| Board | Every Pin names a board | The selector lists boards the connected account can write to |
Planning a catalogue push
Pinterest rewards repetition and a steady supply of fresh images, which is a batching problem, not a writing problem. The practical shape is a queue per board: ten product Pins for a collection, three lifestyle images around them, then a gap, then the next collection. The calendar holds that shape and the media library holds the crops, so a second week does not start from a shared drive.
Seasonal demand matters more than the hour of posting. A Pin published in October competes for Christmas searches, and the same Pin republished in January is late. Plan backwards from the season, not forwards from today, and keep the destination link current so a sold-out product does not send traffic to a dead page.
Approvals apply here as they do elsewhere. A client can review a board's worth of Pins in one pass, because the review happens on the post record rather than in a message thread, and a rejected Pin keeps the reviewer's note next to it.
What Pinterest scheduling costs
Pinterest itself schedules Pins for free, one at a time. Paid tools earn their place when Pins are part of a multi-network plan. The table uses verified vendor figures from 30 October 2026.
| Plan | Price | What you get for Pinterest |
|---|---|---|
| Buffer Essentials | $5 per channel / month | One Pinterest channel, one user, unlimited scheduled posts |
| Buffer Team | $10 per channel / month | The same channel with unlimited users and approvals |
| Later Starter | $18.75 / month, billed yearly | One social set of eight profiles, one user, AI credits sold separately |
| PostSider Standard | $20 flat / month | Five channels including Pinterest, one seat, API, MCP and SDK |
| PostSider Team | $35 flat / month | Ten channels, unlimited seats, approvals, unlimited posts |
Sources, read 30 October 2026: buffer.com/pricing (Essentials $5 per channel, Team $10 per channel, annual billing) and later.com/pricing (Starter $18.75 per month billed yearly, one social set of eight profiles, extra social set $11.25, extra user $3.75). PostSider prices come from /pricing/. One Pinterest channel alone is cheaper on Buffer Essentials at $5; the flat tier only wins once several networks share the calendar.
What PostSider does not do on Pinterest
- No comment or message inbox. Community replies stay in Pinterest.
- No image generation or automatic cropping to the 2:3 ratio. Prepare the crop before you upload.
- No RSS auto-posting and no automatic re-pinning of your evergreen Pins.
- No guarantee Pinterest accepts a file. Video processing happens on Pinterest's side.
Where this fits
Stores and catalogue teams should read the ecommerce workflow, which puts Pins beside Instagram, Facebook and TikTok in one drop plan. Agencies running several brands will find the agency workflow more relevant, because the board per client problem is really an organization problem. If the decision is between per-channel and flat pricing, the Buffer alternatives comparison does that maths, and the pricing page lists the current limits.
Why use it
Pinterest scheduling without another isolated workflow.
Use the same calendar, approvals and publishing workflow you already use for the rest of your social stack.
Keep Pins and the rest of the network plan on one calendar, with the same approval step a client already uses for other channels.
Reuse the product imagery already in the media library instead of re-uploading the same shot to Pinterest in a second tab.
Workflow
From draft to published in one queue.
Connect the Pinterest account and choose a board
Pinterest publishing requires a board. The connection asks for boards:read and boards:write, and each scheduled Pin names the board it publishes to, so a campaign cannot land on the wrong list by accident.
Attach the media the Pin actually needs
A Pin needs at least one image. Images may be up to five, and every image in one Pin must share the same width and height. A video Pin needs exactly one MP4 plus one cover image, nothing else.
Schedule, then check the published Pin
Pins queue like any other post and publish at the planned time. After that, open the Pin to confirm the board, the destination link and the image crop, because a scheduled Pin is not proof that Pinterest accepted it.
Humans + AI agents
Use the calendar yourself or publish programmatically.
PostSider exposes the same social publishing workflow through MCP, REST and an SDK, so automations and AI agents can work alongside your team.

FAQ
Pinterest scheduling, answered.
What is a Pinterest post scheduler?
A scheduler queues Pins with their image, destination link and board, then publishes them at the planned time. PostSider keeps Pins in the same calendar as the other networks, so a product campaign is planned once.
How do I schedule Pinterest posts with PostSider?
Connect the Pinterest account, choose a board, attach the image or the video and cover pair, write the Pin text, then pick a date and time. The per-network preview shows the crop before the Pin queues.
How many images can one Pin have?
Up to five, and all of them must have the same width and height. PostSider rejects a mixed-size set before publishing, which is the most common cause of a failed multi-image Pin.
Can I schedule video Pins?
Yes, with a strict shape: exactly one MP4 video plus exactly one cover image, and nothing else attached. A video Pin with two covers or an extra image fails validation before it reaches Pinterest.
Does a Pin need a board and a destination link?
A board is required, because Pinterest has no default board for API publishing. The destination link is optional but is the whole point of a commercial Pin, so the composer expects it for product work.
Is a Pinterest scheduler worth paying for?
If Pinterest is one of several networks, yes, because the alternative is a second calendar and a second approval habit. If Pinterest is the only channel, the native scheduler in Pinterest is free and PostSider adds nothing.
What does PostSider not do on Pinterest?
No inbox for comments or messages, no image generation, no automatic re-pinning of evergreen content, and no analytics beyond the post and channel figures PostSider already collects.
