# startCustomIntegrations()

> Starts one or more custom integrations in Daily Prebuilt.

`startCustomIntegrations(id)`

<Badge color="green">{"✓"} Prebuilt</Badge> <Badge color="red">{"✗"} Custom</Badge>

Integrations are referenced by their ID — the key used when defining them in the `customIntegrations` object.

## Parameters

<ParamField body="id" type="string | string[]" required>
  A single integration ID or array of integration IDs to start.
</ParamField>

## Return value

Returns `this` for chaining.

```javascript theme={null}
// Start a single integration
call.startCustomIntegrations('miroEmbed');

// Start multiple integrations at once
call.startCustomIntegrations(['miroEmbed', 'figmaEmbed']);
```
