# Integrations

> Connect supported payment, access control, communication, accounting, Wi-Fi, and operational services to Nexudus.

## Overview

Use **Integrations** to connect Nexudus with services you already use to run your location. Available integrations vary by your Nexudus subscription, enabled modules, region, and the services configured for the selected location.

Go to **Settings → Integrations**. You need administrator access or the permission required by the integration.

## Connect an integration

<Steps>

  </Step>

  <Step title="Open Integrations">
    In Settings, select **Integrations**, then choose the service you want to connect.
  </Step>

  <Step title="Review prerequisites">
    Confirm that the service account, subscription, hardware, API access, and any required Nexudus module are ready.
  </Step>

  <Step title="Connect and authorise">
    Enter the requested credentials or use the provider's authorisation flow. Save the configuration.
  </Step>

  <Step title="Test and monitor">
    Use the connection or sync action where available, then verify its status and any relevant operational workflow.
  </Step>
</Steps>

## Connection status

An integration can show as connected, disconnected, or requiring attention. Some integrations also provide a **Synchronise** action. Use this after initial setup or when the provider requires a manual refresh.

<Warning>
  Disconnecting an integration can stop payment collection, access updates, synchronisation, or customer communications. Check the effect on active customers and operational workflows before disconnecting it.
</Warning>

## Best practices

* Use a dedicated service account where the provider supports one.
* Keep API credentials and OAuth access current, and update them only in the integration's configuration.
* Test with a non-critical transaction, reservation, or user before relying on a new connection.
* Review each integration after changing payment providers, access hardware, a custom domain, or your location network.
