Company profile, invoicing profile, users and roles, notifications, and the credentials for connecting your systems.

Settings has eight sections.

### General

Application settings — currently the interface language.

### Profile

Company details: trade name, company ID, tax ID, VAT ID, Peppol ID, address,
contact email and phone. Changes are stored with the **Save** button.

### Invoicing profile

The details prefilled into every invoice issued in the portal: VAT mode,
registry entry, IBAN and payment terms, the issuer's contact, and the number
series for invoices and credit notes. Only an administrator sees and changes
this section. Details are in [Issuing an invoice in the
portal](/help/en/portal/vystavenie-faktury/).

### Users

Management of organisation members; requires the administrator role. The list
shows the role, status, last sign-in and multi-factor authentication status.
You invite a user by email, can resend or revoke the invitation, change the
role, and deactivate or reactivate the account.

| Role | What it can do |
|---|---|
| **Admin** | Full management, including users and credentials. |
| **Operator** | Work with invoices, including issuing them in the portal. |
| **Viewer** | Read only. |

### Notifications

For each event type you switch the **Email** and **In-app** channels on or
off. The setting is personal — it applies to the signed-in user, not the whole
organisation.

It covers invoice delivered, rejected and received, low and exhausted credit,
an approaching certificate or token expiry, and rejected TDD.

### Credentials for connecting systems

Three sections serve integration with your own software:

- **API keys** — keys for programmatic access to the REST API. You create
  them with a name and a role; the list shows the prefix and last use.
- **Webhooks** — HTTP notifications about events into your system. You add a
  URL, select the events, and can test delivery.
- **SAPI clients** — OAuth2 service accounts for connecting an ERP through
  SAPI-SK. Creating one gives you a Client ID and Client Secret.

**Both the API key and the Client Secret are shown only once.** Store them
right away — they cannot be displayed again, only replaced with a new one.
Revoking a SAPI client is irreversible and any integration using it stops
working immediately.

The technical details — authentication, request shapes, webhook signature
verification and the event catalogue — are in the [integration
guide](/developers/en/).
