Authentications
The node allows you to define authentication data, save them, and use them for a connection with data sources. The node includes two subnodes, namely OAuth2 App -> API and OAuth2 User -> API, which determine the type of authentication.

1. ID
The unique identifier of an element containing authentication data. A negative number displayed in this field indicates that the changes to the element have not been saved.
2. Name
The user-defined name of an element containing authentication data.
3. Type
The field allows you to select one of the two available authentication types:
- OAuth2 App -> API – authentication utilizes the OAuth2 Authorization Client Credentials Grant Flow (grant_type=client_credentials) to obtain an access token. This process does not require any action from the user. It is recommended to employ this authentication type in scenarios where the API connection is established within the context of a client application, rather than the current user.
- OAuth2 User -> API – the authentication uses the OAuth2 Authorization Code Flow (grant_type=authorization_code) method to obtain an access token. It may require the user to log in and grant the application the permission to access to their data.
4. Description
A optional, user-defined description for an element containing authentication data.
