# Adds a user to a schedule group, or sets their lead flag when already a member.

`PUT /api/v1/schedule-groups/{id}/members/{userId}`

## Request

- Base URL: `https://app.flexonthejob.com`
- URL: `https://app.flexonthejob.com/api/v1/schedule-groups/{id}/members/{userId}`
- Auth: HTTP bearer

Requires `ManageJobs` and an `Idempotency-Key` header. The user must be an active
user of this organization (ids from `GET /api/v1/users`). A user may belong to several
groups. Example: `PUT /api/v1/schedule-groups/7/members/3f2a…` with `{ "isLead": true }`.

## Path parameters

- `id` integer, required
- `userId` string, required

## Request body

- ScheduleGroupMemberWriteApiRequest: Body of `PUT /api/v1/schedule-groups/{id}/members/{userId}`. May be empty. Example: `{ "isLead": true }`.
  - `isLead` boolean, nullable: True makes the user a crew lead / foreman of this group (listed first), false a regular member. Omit to keep the current flag (a newly added member is not a lead).

## Response `200`

The group with its members after the change.

- ScheduleGroupDto: A scheduling group (division, crew or team) of the calling organization, as returned by `GET /api/v1/schedule-groups`. Groups form a tree via `parentGroupId`; a user may belong to several groups. Requires the `scheduling` module.
  - `id` integer: Numeric id of the group. Stable within this organization.
  - `syncId` string, uuid: Globally unique sync id (GUID). Use it as the `after` pagination cursor.
  - `name` string: Group name, e.g. `"Install Crew A"`.
  - `description` string, nullable: Optional description shown on the dispatch board.
  - `colorHex` string, nullable: Hex colour used for calendar / board rendering, e.g. `"#2e7d32"`; null when unset.
  - `parentGroupId` integer, nullable: Id of the parent group (e.g. the division a crew belongs to); null for top-level groups.
  - `parentGroupName` string, nullable: Name of the parent group; null for top-level groups.
  - `displayOrder` integer: Sort position among siblings (ascending). Pages are returned in id order, so sort by this client-side when rendering a board.
  - `members` ScheduleGroupMemberDto[]: Members of this group, leads first. Only active users are listed.
    - `userId` string: User id (string GUID) — matches `id` from `GET /api/v1/users` and job assignee ids.
    - `displayName` string: User's display name, e.g. `"Sam Carter"`.
    - `isLead` boolean: True for the crew lead / foreman of this group.
  - `createdAt` string, date-time: UTC creation timestamp.
  - `updatedAt` string, date-time, nullable: UTC timestamp of the last edit; null when never edited.
