SuccessFactors Auth

Authenticate with the SAP SuccessFactors API with OAuth2 and Python.

Dependencies

• xmlsec
• requests

System Requirements

• libxml2 >= 2.9.1
• libxmlsec1 >= 1.2.18

How to use

1. Create an OAuth application in SuccessFactors.
2. Download the private key and copy the Client ID.
3. Install the Python module:

   pip install successfactors_auth
   

   Depending on your OS, you may need to install additional system packages, see xmlsec documentation.
   Note for macOS users: There is a bug that prevents you from installing xmlsec with Homebrew, currently tracked in a Github issue. There are some workaround you can try, but in the mean time it may be easier to install within a container or VM.
4. Import successfactors_auth into your Python >=3.9 project.
5. Call the successfactors_auth.get_token() function in your Python project. You'll need to pass the following parameters:
   • sf_url: Base API url of your SuccessFactors instance, e.g. "https://api55.sapsf.eu".
   • sf_company_id: SuccessFactors company ID.
   • sf_oauth_client_id: The Client ID for the OAuth application you created earlier.
   • sf_admin_user: An admin user in SuccessFactors that has access to the OAuth application.
   • sf_saml_private_key: Path to the private key file you downloaded when you created the OAuth application.

Example

#!/usr/bin/env python

import requests
import successfactors_auth as sf

sf_url = 'https://your.base.url.com'
sf_company_id = 'your-company-id'
sf_oauth_client_id = 'your_app_client_id'
sf_admin_user = 'your_admin_user'
sf_saml_private_key = 'app_private_key_file.pem'

token = sf.get_token(
    sf_company_id=company_id,
    sf_oauth_client_id=oauth_client_id,
    sf_admin_user=admin_api_user,
    sf_saml_private_key=oauth_private_key,
    sf_url=url
)

headers = {
    "Accept: application/json",
    f"Authorization: {token}"
}

request = requests.get(f"{sf_url}/User", headers=headers)
user = request.json()

print(user)

Background

I wrote this module because I was forced to deal with the horrific SAP SuccessFactors API at my job, and I wanted to make sure other devs/sysadmins wouldn't have to feel the pain that I felt.

Once you get authenticated, getting the information you want is a whole new level of suffering. I hope to publish some more examples in the form of a blog post or docs in this repo.
