}Call ads.build_audience
Create an audience for this brand — ‘make an audience from our customer list’, ‘retarget people who visited the site’, ‘an audience of everyone who opened our sign-up form’. A customer list starts empty: the operator adds their contacts or a list on the audiences page, and that step stops for a person to approve. Every other kind the ad platform fills itself from the brand’s own pixel, Page, Instagram, sign-up forms or video ads, and has no size until it finishes matching. Never claim an audience has people in it unless its size says so. Not for an audience of people who resemble one of these — that is ads.build_lookalike.
Every result names the workspace it ran in. Say which workspace the answer is about. When the account has more than one workspace and none is selected, this tool refuses with workspace_ambiguous and lists the choices — offer them, never pick one.

}Authorizations
An API key minted at Settings › API & MCP. Send it as Authorization: Bearer <key>. A key carries its holder's own permissions, resolved on every call — revoking a membership closes the key's reach immediately. Keep it in an environment variable (GOOSY_API_KEY), never in a committed file.
Headers
Body
Who is in it: customer_list (the brand's own customers, added after), website (people who visited the site), page_engagement (people who engaged with the Facebook Page or its ads), instagram_engagement (people who engaged with the Instagram account or its ads), lead_form_opened or lead_form_submitted (people who opened, or sent, a Meta sign-up form), video_viewers (people who watched a video ad). Leave it out for customer_list.
customer_list, website, page_engagement, instagram_engagement, lead_form_opened, lead_form_submitted, video_viewers Response
The call was admitted and dispatched. ok says whether the tool succeeded — a refusal the tool itself produced is still a 200, exactly as it is a successful JSON-RPC result over MCP.
- Option 1
- Option 2
The tool ran and answered.
