You can set up a simple scheduled check using the ArcGIS Enterprise Admin REST API. Both Portal and Server expose license details under /system/licenses. A small Python/PowerShell script can pull the expiration date, compare it with today, and if less than 30 days remain, trigger an email/Teams/Slack alert. I usually recommend scheduling it daily (Task Scheduler or cron) so admins get proactive notifications and avoid any last-minute disruptions.
Using the ArcGIS Enterprise REST Admin API
Portal and Server both expose license info via the admin API.
The JSON response includes details like expiration date.
You can write a Python/PowerShell script that:
Authenticates with admin credentials.
Fetches license details.
Compares today’s date with expiration date.
If < 30 days remaining, send an email, Teams/Slack message, or log entry.
Python Example (Portal)
import requests
import datetime
import smtplib
portal_url = "https://yourportal.domain.com:7443/arcgis/portaladmin/system/licenses"
username = "admin"
password = "yourpassword"
# Get token
token_url = "https://yourportal.domain.com:7443/arcgis/sharing/rest/generateToken"
payload = {
"username": username,
"password": password,
"client": "requestip",
"f": "json"
}
token = requests.post(token_url, data=payload, verify=False).json()["token"]
# Get license info
params = {"token": token, "f": "json"}
resp = requests.get(portal_url, params=params, verify=False).json()
expiration_str = resp["licenses"][0]["expiration"] # adjust index based on structure
expiration_date = datetime.datetime.strptime(expiration_str, "%Y-%m-%d")
days_left = (expiration_date - datetime.datetime.today()).days
if days_left <= 30:
# Example: Send email
server = smtplib.SMTP("smtp.yourdomain.com", 25)
msg = f"Subject: ArcGIS License Expiration Alert\n\nLicense expires in {days_left} days!"
server.sendmail("noreply@yourdomain.com", "admin@yourdomain.com", msg)
server.quit()
