# SAP SuccessFactors - How do I link my account?
# Overview
To authenticate with SAP SuccessFactors, you need:
1. **API Server** - The base URL of your SAP SuccessFactors OData API instance.
2. **Company ID** - Your company's unique identifier in SAP SuccessFactors.
3. **API Key** - The API Key (Client ID) generated during the OAuth client application registration process in SAP SuccessFactors.
4. **Private Key** - The private key extracted from the X.509 certificate downloaded from SAP SuccessFactors.
5. **Username** - Your SAP SuccessFactors username.
Nango will automatically generate the SAML Assertion using these credentials during the authentication process.
This guide will walk you through obtaining these credentials within SAP SuccessFactors.

2. In the listed API Server URLs, search for the environment that matches your subdomain.
* For example, if your domain was https\://**salesdemo4**.successfactors.com, search for **salesdemo4**.

1. In your **Admin Center**, go to Tools, and search **Manage OAuth2 Client Applications**.
2. Click **Register Client Application**.
3. Fill out **Application Name** & **Application URL** (what actually goes in these fields is not important, except that the URL has to begin with **https\://**). You can also have a look at this [guide](https://help.sap.com/docs/SAP_SUCCESSFACTORS_PLATFORM/d599f15995d348a1b45ba5603e2aba9b/6b3c741483de47b290d075d798163bc1.html#procedure) on how to fill this form.
