## 2026-05-27 – Workspace invite listing requires admin access

The workspace invite listing endpoint now requires workspace admin access:

* `GET /open/workspaces/{workspaceId}/invites`

### What changed

* Non-admin workspace members can no longer list pending or accepted workspace invites.
* Personal Access Tokens must include `workspaces-write` and belong to a workspace admin.
* Invite responses do not expose invite tokens.

### Migration guide

If your integration lists workspace invites, use an admin-owned token with the `workspaces-write` ability. Continue using `GET /open/workspaces/{workspaceId}/users` with `workspace-users-read` when you only need accepted workspace members.

## 2025-01-02 – Optimized form list endpoint

The form list endpoint now returns **lightweight form summaries** for improved performance:

* `GET /open/workspaces/{workspaceId}/forms`

<Info>
  The deprecated `GET /open/forms` endpoint (which lists all forms across workspaces) has been removed from the documentation. It remains available for existing Zapier integrations but is not recommended for new implementations.
</Info>

### What changed

This endpoint no longer includes the `properties` array (form fields and blocks) in the response. This significantly reduces response size and improves load times, especially for workspaces with many forms or complex form structures.

### Response fields

The list endpoint now returns these fields:

| Field                                                        | Description                            |
| ------------------------------------------------------------ | -------------------------------------- |
| `id`, `slug`, `title`, `visibility`, `tags`                  | Core form identification               |
| `views_count`, `submissions_count`                           | Form statistics                        |
| `created_at`, `updated_at`, `last_edited_human`              | Timestamps (ISO 8601 + human-readable) |
| `closes_at`, `is_closed`                                     | Form closure status                    |
| `max_submissions_count`, `max_number_of_submissions_reached` | Submission limits                      |
| `is_pro`, `workspace_id`, `share_url`                        | Workspace and sharing info             |

### Migration guide

If your integration relies on `properties` from list endpoints, update your code to:

1. Fetch the form list to get form IDs/slugs
2. Call `GET /open/forms/{slug}` for each form where you need the full `properties` array

```javascript theme={null}
// Before: properties were included in list response
const forms = await fetch('/open/workspaces/1/forms');

// After: fetch full form details when needed
const formList = await fetch('/open/workspaces/1/forms');
const fullForm = await fetch(`/open/forms/${formList.data[0].slug}`);
// fullForm.properties is now available
```
