Ask ChatGPT for Pinterest posts

Example prompts and the steps to expect. These are illustrations, not recorded conversations.

Example prompt

“Make a Pin of this recipe photo for my Kitchen ideas board with a title and a link to the recipe, and hold it for my review on Sunday morning.”

Example prompt

“Turn these four product photos into a carousel Pin with alt text for each, on the board you think fits best, and leave it for me to approve.”

Example prompt

“Which boards do I have on Pinterest? Suggest one Pin a day for next week and save them as drafts.”

What Wahlu does on Pinterest

ChatGPT works through Wahlu's tools, so it can set the Pinterest options Wahlu supports.

Pinterest settings on a draft

Board
Required. Your agent lists the account's boards and asks which one to use.
Section
An optional section of the board.
Title and link
A title up to 100 characters and the page the Pin opens.
Alt text
A description of the image for screen readers.

Pinterest asks that you choose each Pin yourself, so confirm each Pin; looping queues, Autopilot and flows don't post to Pinterest. Only business accounts can connect.

The tool calls, in order

  1. 01

    list_targetsFinds the brand's connected Pinterest account and checks it's ready.

  2. 02

    import_media_from_url, upload_media or list_mediaBrings in the image or video, or picks one from your media library.

  3. 03

    create_draftCreates the draft with its caption and pinterest_settings, such as the post type.

  4. 04

    preflight_draftChecks the draft against Pinterest's rules without changing it.

  5. 05

    create_schedulePuts it on the calendar at pending_review, held for your approval.

Pinterest limits to know

Wahlu checks these before a post is scheduled, so the agent finds out early.

Getting images and video to Pinterest

The hosted connection can't open files on your computer. Give the agent a public link to import, pick from your brand's media library, or attach an image the agent can pass on as data. For video, a public link or your media library is usually easiest.

Connect ChatGPT to Wahlu

Set this up once and ChatGPT can work on every network you've connected, not just Pinterest.

  1. 1

    On chatgpt.com, open Settings → Security and login and turn on Developer mode.

  2. 2

    Go to chatgpt.com/plugins and select the + button.

  3. 3

    Name it Wahlu, paste https://mcp.wahlu.com/mcp as the MCP server URL and choose OAuth if asked how to authenticate.

  4. 4

    Create the connection and sign in to Wahlu when asked.

  5. 5

    Start a new conversation and add Wahlu from the tools menu.

Checked against the OpenAI developer docs on 24 September 2026. Menus can change; if a step doesn't match what you see, follow the vendor's current instructions.

Set this up on the ChatGPT website; the desktop apps don't have developer mode. Whether developer mode is available depends on your ChatGPT plan and workspace settings, and a workspace admin may need to allow it.

You stay in control.

Every Wahlu plan includes agent access, through MCP and the API. You choose the workspace, brands and permissions each connection gets, and can disconnect it at any time.

Held until you approve

Agents create schedules at pending_review unless you've told them to publish. A held schedule can't publish until you approve it in Wahlu or ask an agent with Publishing permission to approve it.

Publishing is its own permission

Publishing is separate from Manage your schedule. Leave it unticked and nothing your agent schedules can go out on its own.

Checked before it's scheduled

preflight_draft reports anything that would stop a post, such as media the network won't accept or a caption that's too long, without changing anything.

Some things stay in the app

Use the app for queues, draft media and platform settings, and connecting social accounts. Agents can change the name or caption of an unused draft and approve held schedules with the right permissions.
