Use the OAuth authentication standard to connect to SAP HANA XSA V3 API. You can authenticate with a user account. The driver facilitates this as described below.

User Accounts

The user account flow requires the authenticating user to interact with SAP HANA XSA via the browser.

Creating a Custom OAuth App

You will need to create a custom OAuth app to connect to data. See Creating a Custom OAuth App for a procedure.

Custom Credentials

You can register an app to obtain the OAuthClientId and OAuthClientSecret.

When to Create a Custom OAuth App

Web Applications

You need to create a custom OAuth app in the web flow.

Desktop Applications

You will need to create a custom OAuth app to connect.

Headless Machines

In the headless OAuth flow, users need to authenticate via a browser on another machine. You will need to create a custom OAuth app to connect.

Using a Service Account to Connect to SAP HANA XSA

Service accounts have silent authentication, without user authentication in the browser. You can also use a service account to delegate enterprise-wide access scopes to the driver.

You need to create an OAuth application in this flow. You can then connect to SAP HANA XSA data that the service account has permission to access. See Custom Credentials for an authentication guide.
