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.

Custom Fields values appear in the format: custom.{custom_field_id}. See Custom Fields.

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 to search for objects that reference the Custom Object Instance.
