If a record is found with the same value for the matching attribute, that record will be updated. If no record with the same value for the matching attribute is found, a new record will be created instead. If you would like to avoid matching, please use the [Create record endpoint](/reference/post_v2-objects-object-records).

If the matching attribute is a multiselect attribute, new values will be added and existing values will not be deleted. For any other multiselect attribute, all values will be either created or deleted as necessary to match the list of supplied values.

Required scopes: `record_permission:read-write`, `object_configuration:read`.

List all lists

Creates a new list.

Once you have your list, add attributes to it using the [Create attribute](/reference/post_v2-target-identifier-attributes) API, and add records to it using the [Add records to list](/reference/post_v2-lists-list-entries) API. 

New lists must specify which records can be added with the `parent_object` parameter which accepts either an object slug or an object ID. Permissions for the list are controlled with the `workspace_access` and `workspace_member_access` parameters.

Please note that new lists must have either `workspace_access` set to `"full-access"` or one or more element of `workspace_member_access` with a `"full-access"` level. It is also possible to receive a `403` billing error if your workspace is not on a plan that supports either advanced workspace or workspace member-level access for lists.
