List Custom Object instances
The `lead_id` parameter is required. If you want to retrieve all Custom Object instances regardless of the lead, you will need to use [Advanced Filtering](https://developer.close.com/api/resources/advanced-filtering).
Custom Fields values appear in the format: `custom.{custom_field_id}`. See [Custom Fields](https://developer.close.com/api/resources/custom-fields/custom-fields-custom-object).
Back references to each Custom Object are not collected in this response. If you need to access this information, please use the `back_reference_fields` on the Custom Object Type and [Advanced Filtering](https://developer.close.com/api/resources/advanced-filtering) to search for objects that reference the Custom Object Instance.
