# List a booking's custom objects (alternate path)

> Lists the custom objects defined for orders, by the `custom_objects_instances` path.

Another path to List a booking's custom objects: it returns the same body, one page under `data`. Other fields filter as `filter_<field>` for equality and `filter_<field>_<operator>` otherwise.

> [!NOTE]
>
> The SDK samples get their client from credentials your app registers once when it starts, as shown in [Authentication](https://exsited.mintlify.site/authentication.md#set-up-a-client). To try the call here, click **Try it**, set `host` to your Exsited API host name and paste an access token from [Get an access token](https://exsited.mintlify.site/api-reference/authentication/get-an-access-token.md).
