Azure App Configuration SDK for Python

\n

Centralized configuration management with feature flags and dynamic settings.

\n

Installation

\n
pip install azure-appconfiguration\n
\n

Environment Variables

\n
AZURE_APPCONFIGURATION_ENDPOINT=https://<name>.azconfig.io  # Required for Entra ID auth\nAZURE_TOKEN_CREDENTIALS=prod # Required only if DefaultAzureCredential is used in production\n
\n

Authentication & Lifecycle

\n
\n

\uD83D\uDD11 Two rules apply to every code sample below:

\n
    \n
  1. Prefer DefaultAzureCredential. It works locally (Azure CLI / VS Code / Developer CLI) and in Azure (managed identity, workload identity) with no code change. Avoid connection strings, account/API keys — they bypass Entra audit and rotation.\n
      \n
    • Local dev: DefaultAzureCredential works as-is.
      • \n
    • Production: set AZURE_TOKEN_CREDENTIALS=prod (or AZURE_TOKEN_CREDENTIALS=<specific_credential>) to constrain the credential chain to production-safe credentials.
      • \n
    \n
    2. \n
  2. Wrap every client in a context manager so HTTP transports, sockets, and token caches are released deterministically:\n
      \n
    • Sync: with <Client>(...) as client:
      • \n
    • Async: async with <Client>(...) as client: and async with DefaultAzureCredential() as credential: (from azure.identity.aio)
      • \n
    \n
    3. \n
\n

Snippets may abbreviate this setup, but production code should always follow both rules.

\n
\n
import os\nfrom azure.appconfiguration import AzureAppConfigurationClient\nfrom azure.identity import DefaultAzureCredential, ManagedIdentityCredential\n\n# Local dev: DefaultAzureCredential. Production: set AZURE_TOKEN_CREDENTIALS=prod or AZURE_TOKEN_CREDENTIALS=<specific_credential>\ncredential = DefaultAzureCredential(require_envvar=True)\n# Or use a specific credential directly in production:\n# See https://learn.microsoft.com/python/api/overview/azure/identity-readme?view=azure-python#credential-classes\n# credential = ManagedIdentityCredential()\n\nwith AzureAppConfigurationClient(\n    base_url=os.environ[\"AZURE_APPCONFIGURATION_ENDPOINT\"],\n    credential=credential\n) as client:\n    # Use client here (see following sections for operations)\n    ...\n
\n

Configuration Settings

\n

Get Setting

\n
setting = client.get_configuration_setting(key=\"app:settings:message\")\nprint(f\"{setting.key} = {setting.value}\")\n
\n

Get with Label

\n
# Labels allow environment-specific values\nsetting = client.get_configuration_setting(\n    key=\"app:settings:message\",\n    label=\"production\"\n)\n
\n

Set Setting

\n
from azure.appconfiguration import ConfigurationSetting\n\nsetting = ConfigurationSetting(\n    key=\"app:settings:message\",\n    value=\"Hello, World!\",\n    label=\"development\",\n    content_type=\"text/plain\",\n    tags={\"environment\": \"dev\"}\n)\n\nclient.set_configuration_setting(setting)\n
\n

Delete Setting

\n
client.delete_configuration_setting(\n    key=\"app:settings:message\",\n    label=\"development\"\n)\n
\n

List Settings

\n

All Settings

\n
settings = client.list_configuration_settings()\nfor setting in settings:\n    print(f\"{setting.key} [{setting.label}] = {setting.value}\")\n
\n

Filter by Key Prefix

\n
settings = client.list_configuration_settings(\n    key_filter=\"app:settings:*\"\n)\n
\n

Filter by Label

\n
settings = client.list_configuration_settings(\n    label_filter=\"production\"\n)\n
\n

Feature Flags

\n

Set Feature Flag

\n
from azure.appconfiguration import ConfigurationSetting\nimport json\n\nfeature_flag = ConfigurationSetting(\n    key=\".appconfig.featureflag/beta-feature\",\n    value=json.dumps({\n        \"id\": \"beta-feature\",\n        \"enabled\": True,\n        \"conditions\": {\n            \"client_filters\": []\n        }\n    }),\n    content_type=\"application/vnd.microsoft.appconfig.ff+json;charset=utf-8\"\n)\n\nclient.set_configuration_setting(feature_flag)\n
\n

Get Feature Flag

\n
setting = client.get_configuration_setting(\n    key=\".appconfig.featureflag/beta-feature\"\n)\nflag_data = json.loads(setting.value)\nprint(f\"Feature enabled: {flag_data['enabled']}\")\n
\n

List Feature Flags

\n
flags = client.list_configuration_settings(\n    key_filter=\".appconfig.featureflag/*\"\n)\nfor flag in flags:\n    data = json.loads(flag.value)\n    print(f\"{data['id']}: {'enabled' if data['enabled'] else 'disabled'}\")\n
\n

Read-Only Settings

\n
# Make setting read-only\nclient.set_read_only(\n    configuration_setting=setting,\n    read_only=True\n)\n\n# Remove read-only\nclient.set_read_only(\n    configuration_setting=setting,\n    read_only=False\n)\n
\n

Snapshots

\n

Create Snapshot

\n
from azure.appconfiguration import ConfigurationSnapshot, ConfigurationSettingFilter\n\nsnapshot = ConfigurationSnapshot(\n    name=\"v1-snapshot\",\n    filters=[\n        ConfigurationSettingFilter(key=\"app:*\", label=\"production\")\n    ]\n)\n\ncreated = client.begin_create_snapshot(\n    name=\"v1-snapshot\",\n    snapshot=snapshot\n).result()\n
\n

List Snapshot Settings

\n
settings = client.list_configuration_settings(\n    snapshot_name=\"v1-snapshot\"\n)\n
\n

Async Client

\n
from azure.appconfiguration.aio import AzureAppConfigurationClient\nfrom azure.identity.aio import DefaultAzureCredential\n\nasync def main():\n    async with DefaultAzureCredential() as credential:\n        async with AzureAppConfigurationClient(\n            base_url=endpoint,\n            credential=credential\n        ) as client:\n            setting = await client.get_configuration_setting(key=\"app:message\")\n            print(setting.value)\n
\n

Client Operations

Best Practices

\n
    \n
  1. Pick sync OR async and stay consistent. Do not mix azure.xxx sync clients with azure.xxx.aio async clients in the same call path. Choose one mode per module.
    2. \n
  2. Always use context managers for clients and async credentials. Wrap every client in with Client(...) as client: (sync) or async with Client(...) as client: (async). For async DefaultAzureCredential from azure.identity.aio, also use async with credential: so tokens and transports are cleaned up.
    3. \n
  3. Use labels for environment separation (dev, staging, prod)
    4. \n
  4. Use key prefixes for logical grouping (app:database:, app:cache:)
    5. \n
  5. Make production settings read-only to prevent accidental changes
    6. \n
  6. Create snapshots before deployments for rollback capability
    7. \n
  7. Use Entra ID instead of connection strings in production
    8. \n
  8. Refresh settings periodically in long-running applications
    9. \n
  9. Use feature flags for gradual rollouts and A/B testing
    10. \n
