# Add Workspace To Service Account

`ServiceAccountWorkspaceMember Organization.ServiceAccounts.Workspaces.Add(parameters, cancellationToken = default)`

**POST** `/v1/organizations/service_accounts/{service_account_id}/workspaces`

**Requires an OAuth access token with the `org:admin` scope**, from `ant auth login --scope org:admin` or a workload identity federation rule; Admin API keys are not accepted. See [Manage WIF with the Admin API](https://platform.claude.com/docs/en/manage-claude/wif-admin-api?sdk_languages=csharp).

Add a service account to a workspace with the given `workspace_role`.

Mirror of `POST /workspaces/{workspace_id}/service_accounts`, addressed
from the service-account side; both create the same membership. If the
service account is already an explicit member of the workspace, its
`workspace_role` is replaced with the value supplied here. Archived
workspaces return 400. Archived service accounts cannot be added and are
rejected.

## Parameters

- `WorkspaceAddParams parameters`

  - `required string serviceAccountID` (path parameter)

    ID of the service account.

  - `required string workspaceID`

    Tagged workspace ID to add the service account to.

  - `required NoBillingWorkspaceRole workspaceRole`

    Role to assign to the service account in this workspace.

## Returns

- `class ServiceAccountWorkspaceMember`

  - `JsonElement Type = "service_account_workspace_member"`

  - `required string? CreatedByActorID`

    Tagged ID (`user_...`/`svac_...`) of the actor who created this membership.

  - `required bool? Implicit`

    True when this is the implicit default-workspace membership every service account has when no explicit membership exists. Implicit memberships have role `workspace_user` and cannot be removed.

  - `required string ServiceAccountID`

    Tagged service account ID (`svac_...`).

  - `required string WorkspaceID`

    Tagged workspace ID (`wrkspc_...`).

  - `required WorkspaceRole WorkspaceRole`

    Role of the service account in this workspace. Service accounts cannot hold the `workspace_billing` role.

    - `WorkspaceAdmin("workspace_admin")`

    - `WorkspaceBilling("workspace_billing")`

    - `WorkspaceDeveloper("workspace_developer")`

    - `WorkspaceRestrictedDeveloper("workspace_restricted_developer")`

    - `WorkspaceUser("workspace_user")`

```csharp
using System;
using Anthropic.Models.Organization.ServiceAccounts.Workspaces;
using Anthropic.Models.Organization.Workspaces;

WorkspaceAddParams parameters = new()
{
    ServiceAccountID = "service_account_id",
    WorkspaceID = "workspace_id",
    WorkspaceRole = NoBillingWorkspaceRole.WorkspaceAdmin,
};

var serviceAccountWorkspaceMember = await client.Organization.ServiceAccounts.Workspaces.Add(parameters);

Console.WriteLine(serviceAccountWorkspaceMember);
```
