Overview

The URLCategories class provides functionality to manage URL category objects in Palo Alto Networks' Strata Cloud Manager. This class inherits from BaseObject and provides methods for creating, retrieving, updating, and deleting custom URL categories that can be used in security policies and profiles.

create()	Creates a new URL category	data: Dict[str, Any]	URLCategoriesResponseModel
get()	Retrieves a category by ID	object_id: str	URLCategoriesResponseModel
update()	Updates an existing category	profile: URLCategoriesUpdateModel	URLCategoriesResponseModel
delete()	Deletes a category	object_id: str	None

Basic Configuration

from scm.client import Scm
# Initialize clientclient = Scm(
client_id="your_client_id",
client_secret="your_client_secret",
tsg_id="your_tsg_id"
)
# Access URL categories directly through the client# No need to initialize a separate URLCategories object

Usage Examples

Creating URL Categories

# URL List category configurationurl_list_config = {
"name": "blocked_sites",
"type": "URL List",
"list": ["example.com", "test.com"],
"description": "Blocked websites list",
"folder": "Texas"
}
# Create URL List category using the clienturl_list = client.url_category.create(url_list_config)
# Category Match configurationcategory_match_config = {
"name": "social_media",
"type": "Category Match",
"list": ["social-networking", "personal-sites-and-blogs"],
"description": "Social media categories",
"folder": "Texas"
}
# Create Category Match categorycategory_match = client.url_category.create(category_match_config)

Retrieving URL Categories

# Fetch by name and foldercategory = client.url_category.fetch(name="blocked_sites", folder="Texas")
print(f"Found category: {category.name}")
# Get by IDcategory_by_id = client.url_category.get(category.id)
print(f"Retrieved category: {category_by_id.name}")
print(f"URL list: {category_by_id.list}")

Updating URL Categories

# Fetch existing categoryexisting_category = client.url_category.fetch(name="blocked_sites", folder="Texas")
# Update URL listexisting_category.list.extend(["newsite.com", "anothersite.com"])
existing_category.description = "Updated blocked websites list"
# Perform updateupdated_category = client.url_category.update(existing_category)

Listing URL Categories

# List with direct filter parametersfiltered_categories = client.url_category.list(
folder='Texas',
members=['example.com']
)
# Process resultsfor category in filtered_categories:
print(f"Name: {category.name}")
print(f"Type: {category.type}")
print(f"URLs: {category.list}")
# Define filter parameters as dictionarylist_params = {
"folder": "Texas",
"members": ["social-networking"]
}
# List with filters as kwargsfiltered_categories = client.url_category.list(**list_params)

Filtering Responses

The list() method supports additional parameters to refine your query results even further. Alongside basic filters (like types, values, and tags), you can leverage the exact_match, exclude_folders, exclude_snippets, and exclude_devices parameters to control which objects are included or excluded after the initial API response is fetched.

Parameters:

• exact_match (bool): When True, only objects defined exactly in the specified container (folder, snippet, or device) are returned.
• exclude_folders (List[str]): Provide a list of folder names to exclude.
• exclude_snippets (List[str]): Provide a list of snippet values to exclude.
• exclude_devices (List[str]): Provide a list of device values to exclude.

Examples:

# Only return url_category defined exactly in 'Texas'exact_url_categories = client.url_category.list(
folder='Texas',
exact_match=True
)

for app in exact_url_categories:
print(f"Exact match: {app.name} in {app.folder}")
# Exclude all url_categories from the 'All' folderno_all_url_categories = client.url_category.list(
folder='Texas',
exclude_folders=['All']
)

for app in no_all_url_categories:
assert app.folder != 'All'
print(f"Filtered out 'All': {app.name}")
# Exclude url_categories that come from 'default' snippetno_default_snippet = client.url_category.list(
folder='Texas',
exclude_snippets=['default']
)

for app in no_default_snippet:
assert app.snippet != 'default'
print(f"Filtered out 'default' snippet: {app.name}")
# Exclude url_categories associated with 'DeviceA'no_deviceA = client.url_category.list(
folder='Texas',
exclude_devices=['DeviceA']
)

for app in no_deviceA:
assert app.device != 'DeviceA'
print(f"Filtered out 'DeviceA': {app.name}")
# Combine exact_match with multiple exclusionscombined_filters = client.url_category.list(
folder='Texas',
exact_match=True,
exclude_folders=['All'],
exclude_snippets=['default'],
exclude_devices=['DeviceA']
)

for app in combined_filters:
print(f"Combined filters result: {app.name} in {app.folder}")

Controlling Pagination with max_limit

The SDK supports pagination through the max_limit parameter, which defines how many objects are retrieved per API call. By default, max_limit is set to 2500. The API itself imposes a maximum allowed value of 5000. If you set max_limit higher than 5000, it will be capped to the API's maximum. The list() method will continue to iterate through all objects until all results have been retrieved. Adjusting max_limit can help manage retrieval performance and memory usage when working with large datasets.

# Initialize the client with a custom max_limit for URL categories# This will retrieve up to 4321 objects per API call, up to the API limit of 5000.client = Scm(
client_id="your_client_id",
client_secret="your_client_secret",
tsg_id="your_tsg_id",
url_categories_max_limit=4321
)
# Now when we call list(), it will use the specified max_limit for each request# while auto-paginating through all available objects.all_categories = client.url_category.list(folder='Texas')
# 'all_categories' contains all objects from 'Texas', fetched in chunks of up to 4321 at a time.

Deleting URL Categories

# Delete by IDcategory_id = "123e4567-e89b-12d3-a456-426655440000"
client.url_category.delete(category_id)

Managing Configuration Changes

Performing Commits

# Prepare commit parameterscommit_params = {
"folders": ["Texas"],
"description": "Updated URL categories",
"sync": True,
"timeout": 300 # 5 minute timeout
}
# Commit the changes directly using the clientresult = client.commit(**commit_params)

print(f"Commit job ID: {result.job_id}")

Monitoring Jobs

# Get status of specific job using the clientjob_status = client.get_job_status(result.job_id)
print(f"Job status: {job_status.data[0].status_str}")
# List recent jobs using the clientrecent_jobs = client.list_jobs(limit=10)
for job in recent_jobs.data:
print(f"Job {job.id}: {job.type_str} - {job.status_str}")

Error Handling

from scm.exceptions import (
InvalidObjectError,
MissingQueryParameterError,
NameNotUniqueError,
ObjectNotPresentError,
ReferenceNotZeroError
)

try:
# Create category configuration
category_config = {
"name": "test_category",
"type": "URL List",
"list": ["example.com", "test.com"],
"folder": "Texas",
"description": "Test URL category"
}

# Create the category using the client
new_category = client.url_category.create(category_config)

# Commit changes using the client
result = client.commit(
folders=["Texas"],
description="Added test category",
sync=True
)

# Check job status using the client
status = client.get_job_status(result.job_id)

except InvalidObjectError as e:
print(f"Invalid category data: {e.message}")
except NameNotUniqueError as e:
print(f"Category name already exists: {e.message}")
except ObjectNotPresentError as e:
print(f"Category not found: {e.message}")
except ReferenceNotZeroError as e:
print(f"Category still in use: {e.message}")
except MissingQueryParameterError as e:
print(f"Missing parameter: {e.message}")

Best Practices

1. URL List Management

   • Use descriptive category names
   • Group related URLs together
   • Validate URL patterns before adding
   • Keep lists manageable in size
   • Document category purposes

2. Container Management

   • Always specify exactly one container (folder, snippet, or device)
   • Use consistent container names
   • Validate container existence
   • Group related categories

3. Client Usage

   • Use the unified client interface (client.url_category) for simpler code
   • Perform commits directly on the client (client.commit())
   • Monitor jobs using client methods (client.get_job_status(), client.list_jobs())
   • Initialize the client once and reuse across different object types

4. Category Types

   • Choose appropriate type (URL List vs Category Match)
   • Validate category match patterns
   • Consider URL resolution impact
   • Document type selection rationale

5. Performance

   • Use appropriate pagination
   • Cache frequently accessed categories
   • Implement proper retry logic
   • Monitor URL resolution times

6. Security

   • Follow least privilege principle
   • Validate input URLs
   • Use secure connection settings
   • Monitor category usage
