# Custom content

> Send provider-specific structured payloads.

Use `custom()` to send structured, platform-specific payloads. Reach for this when the receiving provider supports rich content types that don't fit into the built-in builders.

```ts theme={null}
import { custom } from "spectrum-ts";

await space.send(custom({ type: "card", title: "Order Confirmed" }));
```

The raw payload round-trips through the provider's `send` action. The provider decides how to interpret it.

If you need a reusable provider-specific abstraction, wrap `custom()` in your own helper so call sites still read like product-level actions.
