What Wahlu does on Facebook
Claude works through Wahlu's tools, so it can set the Facebook options Wahlu supports.
Facebook settings on a draft
- Post type
- Page post, Reel or Story.
Wahlu posts to Facebook Pages, not personal profiles or groups, and a Page post carries one image or video rather than an album.
The tool calls, in order
- 01
list_targetsFinds the brand's connected Facebook account and checks it's ready. - 02
import_media_from_url,upload_mediaorlist_mediaBrings in the image or video, or picks one from your media library. - 03
create_draftCreates the draft with its caption andfacebook_settings, such as the post type. - 04
preflight_draftChecks the draft against Facebook's rules without changing it. - 05
create_schedulePuts it on the calendar atpending_review, held for your approval.
Facebook limits to know
Wahlu checks these before a post is scheduled, so the agent finds out early.
Page photos can be JPEG, BMP, PNG, GIF or TIFF, up to 10 MB.
Graph API: Page photosReels are 9:16 video between 3 and 90 seconds. Wahlu keeps Reel captions to 2,200 characters.
Meta: Reels publishingStory videos are 9:16, at least 540 × 960, between 3 and 60 seconds.
Meta: Page Stories APIMeta documents no caption limit for Page posts through the API; Wahlu uses Facebook's own composer limit of 63,206 characters.

Getting images and video to Facebook
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.

Checked against the Claude Help Center on 24 September 2026. Menus can change; if a step doesn't match what you see, follow the vendor's current instructions.
The same steps work on claude.ai and in Claude Desktop. On Team and Enterprise plans, an organisation owner first adds the connector in Organization settings → Connectors (Add, then Custom → Web); members then click Connect next to it in Customize → Connectors. Free plans allow one custom connector.
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 the Wahlu calendar.
Publishing is its own permission
Publish to social accounts 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
Queues, general edits to existing drafts, approvals and connecting social accounts happen in the Wahlu app, not through your agent.
