Prerequisites
- Ensure you have an active SAP Leonardo account and API Key.
- Ensure your Gmail account is operational and has API enabled through Google Developer Console.
Enable Gmail API
- Go to the Google Cloud Console and create a new project.
- Enable the Gmail API for your project from the API Library. You will receive credentials (client ID, client secret) for API access.
Authenticate and Obtain Tokens
- Install `google-auth` library to handle OAuth2.0 authentication.
pip install google-auth google-auth-oauthlib
- Set up an OAuth 2.0 consent screen in the Google Cloud Console.
- Download the OAuth credentials JSON file and save it securely.
Connect SAP Leonardo to Gmail
- Open your SAP Leonardo environment.
- Navigate to the integration services section and create a new integration project.
- Add endpoints for Gmail API using the previously obtained client ID and secret.
Write the Integration Code
- Create a Python script to handle interactions between SAP and Gmail. Use the `google-auth` library to authenticate and access Gmail services.
from google.oauth2.credentials import Credentials
from google_auth_oauthlib.flow import InstalledAppFlow
from googleapiclient.discovery import build
# Create a flow instance to manage the OAuth 2.0 authorization process
flow = InstalledAppFlow.from_client_secrets_file(
'path_to_your_client_secret.json',
scopes=['https://www.googleapis.com/auth/gmail.readonly'])
creds = flow.run_local_server(port=0)
service = build('gmail', 'v1', credentials=creds)
results = service.users().messages().list(userId='me', labelIds=['INBOX']).execute()
messages = results.get('messages', [])
- Handle email data within SAP Leonardo platform using its machine learning capabilities or analytics.
Test the Integration
- Send test emails to your connected Gmail account to ensure SAP Leonardo successfully retrieves and processes them.
- Review the data in your SAP Leonardo environment to verify accuracy and performance.
Deployment and Monitoring
- Deploy the integration within your SAP Leonardo cloud deployment environment.
- Set up monitoring to track the performance and handle any errors in the communication flow.
# Example shell command for deploying a cloud integration task in SAP Leonardo
sapcli deploy --project="project_name" --region="us-central1"
- Implement logging within the integration script to facilitate troubleshooting and maintenance.
