# Create audience

> Creates a custom audience.

`metaAds.createAudience` creates a custom audience.

```ts automations/meta-ads-create-audience.automation.ts theme={null}
import { automation, onDashboardRun } from "automate.ax"
import { metaAds } from "automate.ax/meta-ads"

export default automation("Create audience", () => {
  onDashboardRun({ title: "Create audience" })
  const result = metaAds.createAudience({
    adAccountId: "123456789",
    name: "Loyal customers",
    customerFileSource: "USER_PROVIDED_ONLY",
  })
  // Use result in the next advertising, reporting, or delivery operation.
})
```

`subtype` defaults to `CUSTOM`. Declare the correct customer-file source for uploaded identifiers. Optional second argument `{ account }` selects a static project account binding.

Returns the created audience ID. Creation is not replay-safe.
