**Bulk Create**

This endpoint supports bulk creating up to 100 objects. In the request body, set the top-level key to its plural form and place the objects in an array. Example:

```
{
  "participations": [
    {
      "workspace_id": 123,
      "role": "maven",
      "user_id": 111
    },
    {
      "workspace_id": 123,
      "role": "maven",
      "user_id": 222
    }
  ]
}
```


This endpoint returns structured Participation objects.
As with all Kantata OX API endpoints, the returned data will be referenced in sorted order in the `results` array
and will be indexed by ID in the `participations` top-level JSON key.
Please see our [Response Format](#section/Response-Format) section for more information.

## Query parameters

- `include` string
- `optional_fields` string[]

## Request body

- object
  - `participation` object
    - `can_invite` boolean: Permission for the participant to invite other users into the project.
    - `can_schedule_their_hours` boolean: Permission for the participant to schedule their own hours.
    - `can_schedule_team_hours` boolean: Permission for the participant to schedule hours for project team members.
    - `can_edit_todos` boolean: Permission for the participant to edit To Dos.
    - `access_level` string: Access level for the user in the workspace. Valid options include "edit_tasks", "view_tasks", "edit_time_and_expenses", "view_time_and_expenses", "edit_financials", "view_financials", "admin". Legacy options include "financial", "time_logging", "collaboration".
    - `workspace_id` integer, required: The ID of the project the participation will belong to.
    - `role` string, required: The team a participant is on in a project, defined as either the "maven" (provider) or "buyer" (client) team.
    - `user_id` integer: The ID of the user that wants to participate in the project.
    - `permissions` string: Permission for the user in the workspace. It must be any combination of "edit", "view_only", "view_and_post", "can_edit", "can_post", "can_edit_expense", "can_edit_time", "can_invite", "can_schedule_their_hours", or "can_schedule_team_hours" delimited by commas. ex. "can_post,can_edit_time" If "can_invite", "can_schedule_their_hours", or "can_schedule_team_hours" are not set—either via the individual fields or the `permissions` string—they will inherit the default values defined in the account's Project Permissions Defaults.
    - `external_reference` object: Typically populated programmatically by a third party system via an integration, this is an optional object that holds data from an external system. It connects objects in an external system with objects in Kantata OX (for example, to connect a Jira issue to a Kantata OX Project).
      - `service_name` string, required: The provider name of the integration. If you are adding multiple external references to the same object, the `service_name` must be unique.
      - `service_model` string, required: The object type of the external object this external reference belongs to.
      - `service_model_ref` string, required: The object ID of the external object this external reference belongs to.
      - `status` string: The status of the integration. Options are `successful`, `pending`, or `failed`.
