## Add the QuickBooksOnline connection

To create a connection to your QuickBooks instance, you need to perform the following steps:

1. Select Orchestrator from the product launcher.
2. Select a folder, and then navigate to the **Connections** tab.
3. Select **Add connection**.
4. To open the connection creation page, select the connector from the list. You can use the search bar to find the connector.
5. Choose the environment you want to access, **Production** or **Sandbox**, and then select **Connect**.
6. Enter the required credentials for your preferred authentication method. 
7. Select **Connect**.

   For any secret-type field, you can select the menu next to the field and choose **Use credential asset** to reference an Orchestrator credential asset linked to an external vault instead of entering the value directly.
