# POST /api/v1/email/account/actions/webmail-sso

> Get the webmail login page for a mailbox

- Group: email
- Tier: W
- Required scope: write:email
- Docs: https://api.inleed.com/reference/email/webmail-sso

## Description

Returns the mailbox's Roundcube `webmailUrl` on its own node. There is no one-click token — DirectAdmin's webmail tokens are IP-locked and expire in ten seconds, so the user logs in with the full email address and the mailbox password (reset it with `set_mailbox_password` if lost).

## Body

- `address` — string (required)

## Request

```bash
curl -X POST "https://mcp.inleed.com/api/v1/email/account/actions/webmail-sso" \
  -H "Authorization: Bearer inl_live_…" \
  -H "Content-Type: application/json" \
  -d '{"address":"info@example.se"}'
```
