Keycloak Adapter Tutorial¶
The Keycloak adapter provides an interface for interacting with Keycloak's API to manage authentication and authorization. ArchiPy offers both synchronous and asynchronous implementations.
Installation¶
For full API reference, see the Keycloak Adapters API Documentation.
Configuration¶
Configure the Keycloak adapter via environment variables or a KeycloakConfig object.
Environment Variables¶
Warning
Keep KEYCLOAK__CLIENT_SECRET_KEY out of source control. Load it from the environment or a secrets store, and keep
KEYCLOAK__VERIFY_SSL=true outside local development.
KEYCLOAK__SERVER_URL=https://keycloak.example.com
KEYCLOAK__REALM_NAME=my-realm
KEYCLOAK__CLIENT_ID=my-client
KEYCLOAK__CLIENT_SECRET_KEY=client-secret
KEYCLOAK__VERIFY_SSL=true
KEYCLOAK__TIMEOUT=10
KEYCLOAK__TOKEN_LEEWAY_SECONDS=0 # clock-skew tolerance when validating token expiry
KEYCLOAK__REMOTE_CACHE_TTL_SECONDS=0 # opt-in cache for the keycloak auth guards' UserInfo/permission lookups (0 = off)
Direct Configuration¶
from archipy.configs.config_template import KeycloakConfig
config = KeycloakConfig(
SERVER_URL="https://keycloak.example.com",
REALM_NAME="my-realm",
CLIENT_ID="my-client",
CLIENT_SECRET_KEY="client-secret", # noqa: S105
VERIFY_SSL=True,
TIMEOUT=10,
)
Basic Usage¶
The Keycloak adapter provides both synchronous and asynchronous implementations. Use the synchronous adapter for
standard request-response flows and the asynchronous adapter with async/await patterns.
Synchronous Adapter¶
The synchronous adapter provides a blocking API for Keycloak operations.

Asynchronous Adapter¶
The asynchronous adapter provides a non-blocking API using async/await syntax:
import asyncio
import logging
from archipy.adapters.keycloak.adapters import AsyncKeycloakAdapter
from archipy.models.dtos.keycloak.user_dtos import KeycloakUserRequestDTO
from archipy.models.errors import (
InternalError,
InvalidCredentialsError,
ResourceNotFoundError,
PermissionDeniedError,
UnauthenticatedError,
)
logger = logging.getLogger(__name__)
async def main() -> None:
# Initialize with global config
keycloak = AsyncKeycloakAdapter()
try:
# Get token
token = await keycloak.get_token("username", "password")
access_token = token.access_token
except InvalidCredentialsError as e:
logger.error(f"Authentication failed: {e}")
raise
else:
logger.info("Authentication successful")
try:
# Get user info
user_info = await keycloak.get_userinfo(access_token)
logger.info(f"Logged in as: {user_info.preferred_username}")
# Check if user has role
if await keycloak.has_role(access_token, "admin"):
logger.info("User has admin role")
except (UnauthenticatedError, InternalError) as e:
logger.error(f"Failed to get user info or check role: {e}")
raise
try:
# Search for users
users = await keycloak.search_users("john")
logger.info(f"Found {len(users)} users matching 'john'")
# Create a new user
user_data = KeycloakUserRequestDTO(username="async_user", email="async@example.com", enabled=True)
user_id = await keycloak.create_user(user_data)
logger.info(f"Created user with ID: {user_id}")
# Delete the user
await keycloak.delete_user(user_id)
logger.info(f"Deleted user: {user_id}")
except (ResourceNotFoundError, PermissionDeniedError, InternalError) as e:
logger.error(f"User management operation failed: {e}")
raise
# Run the async function
asyncio.run(main())
Advanced Features¶

import logging
from archipy.adapters.keycloak.adapters import KeycloakAdapter
from archipy.models.dtos.keycloak.group_dtos import KeycloakGroupRequestDTO
logger = logging.getLogger(__name__)
keycloak = KeycloakAdapter()
group_id = keycloak.create_group(payload=KeycloakGroupRequestDTO(name="engineering"), skip_exists=True)
groups = keycloak.get_groups()
logger.info("Group %s created; realm has %d groups", group_id, len(groups))

import logging
from archipy.adapters.keycloak.adapters import KeycloakAdapter
logger = logging.getLogger(__name__)
keycloak = KeycloakAdapter()
flows = keycloak.get_authentication_flows()
browser_flow = next(flow for flow in flows if flow.alias == "browser")
logger.info("Browser flow id: %s", browser_flow.id)
Client Scopes¶
import logging
from archipy.adapters.keycloak.adapters import KeycloakAdapter
from archipy.models.dtos.keycloak.client_scope_dtos import KeycloakClientScopeRequestDTO
logger = logging.getLogger(__name__)
keycloak = KeycloakAdapter()
scopes = keycloak.get_client_scopes()
scope_id = keycloak.create_client_scope(
payload=KeycloakClientScopeRequestDTO(name="custom-audience", protocol="openid-connect"),
skip_exists=True,
)
default_scopes = keycloak.get_default_default_client_scopes()
logger.info("Created scope %s; realm has %d default scopes", scope_id, len(default_scopes))
Authorization Services¶
import logging
from archipy.adapters.keycloak.adapters import KeycloakAdapter
from archipy.models.dtos.keycloak.authz_dtos import KeycloakAuthzResourceRequestDTO
logger = logging.getLogger(__name__)
keycloak = KeycloakAdapter()
client_id = keycloak.get_client_id("my-client")
settings = keycloak.get_client_authz_settings(client_id=client_id)
resource = keycloak.create_client_authz_resource(
client_id=client_id,
payload=KeycloakAuthzResourceRequestDTO(name="Account", display_name="Account", uris=["/account/*"]),
skip_exists=True,
)
policies = keycloak.get_client_authz_policies(client_id=client_id)
logger.info("Authz enabled=%s; created resource %s", settings.allow_remote_resource_management, resource.id)
UMA Resource Sets¶
import logging
from archipy.adapters.keycloak.adapters import KeycloakAdapter
from archipy.models.dtos.keycloak.uma_dtos import KeycloakUmaResourceRequestDTO
logger = logging.getLogger(__name__)
keycloak = KeycloakAdapter()
resource = keycloak.resource_set_create(
payload=KeycloakUmaResourceRequestDTO(name="Protected API", scopes=["read", "write"], type="api"),
)
resource_sets = keycloak.resource_set_list()
logger.info("UMA resource %s; total sets=%d", resource.internal_id, len(resource_sets))
Components¶
import logging
from archipy.adapters.keycloak.adapters import KeycloakAdapter
from archipy.models.dtos.keycloak.component_dtos import KeycloakComponentRequestDTO
logger = logging.getLogger(__name__)
keycloak = KeycloakAdapter()
components = keycloak.get_components(query={"type": "org.keycloak.storage.UserStorageProvider"})
component_id = keycloak.create_component(
payload=KeycloakComponentRequestDTO(
name="ldap",
provider_id="ldap",
provider_type="org.keycloak.storage.UserStorageProvider",
),
)
logger.info("Listed %d components; created component %s", len(components), component_id)
DTOs¶
Every Keycloak adapter method takes and returns pydantic DTOs from archipy.models.dtos.keycloak:
- Responses (
KeycloakUserDTO,KeycloakRoleDTO,KeycloakTokenDTO, ...) use snake_case attributes and keep fields unknown to ArchiPy inmodel_extra, so a newer Keycloak never breaks parsing. - Requests (
KeycloakUserRequestDTO,KeycloakGroupRequestDTO, ...) reject unknown fields, so a typo fails before the call instead of as a Keycloak400. to_payload()returns the camelCase JSON Keycloak receives.
from archipy.models.dtos.keycloak.group_dtos import KeycloakGroupRequestDTO
group_id = keycloak.create_group(payload=KeycloakGroupRequestDTO(name="engineering"))
group = keycloak.get_group(group_id)
logger.info("Group %s at %s", group.name, group.path)
Deprecated: dicts
Passing a dict payload and reading results with result["key"] or result.get("key") still work but emit a
DeprecationWarning. Both are removed in 6.0.0. See Create Results and Ids.

import logging
from archipy.adapters.keycloak.adapters import KeycloakAdapter
from archipy.models.dtos.keycloak.client_initial_access_dtos import KeycloakClientInitialAccessCreateRequestDTO
logger = logging.getLogger(__name__)
keycloak = KeycloakAdapter()
keys = keycloak.get_realm_keys()
user = keycloak.get_user_by_username("johndoe")
status = keycloak.get_user_brute_force_status(user.id)
initial_access = keycloak.create_client_initial_access(
KeycloakClientInitialAccessCreateRequestDTO(expiration=3600, count=5),
)
logger.info("Realm keys: %s; brute force status: %s; token: %s", keys, status, initial_access.token)
The same calls work asynchronously:
from archipy.adapters.keycloak.adapters import AsyncKeycloakAdapter
async def lock_status(username: str):
keycloak = AsyncKeycloakAdapter()
user = await keycloak.get_user_by_username(username)
return await keycloak.get_user_brute_force_status(user.id)
Exact signatures
Method names and signatures live in the port classes of
archipy.adapters.keycloak.ports. Many of these calls go through the
admin connection because python-keycloak has no helper for them.
Token Exchange¶
token_exchange takes a KeycloakTokenExchangeRequestDTO and returns a KeycloakTokenExchangeResponseDTO (the issued
token in access_token, its type in issued_token_type). It covers the standard
token exchange V2, the delegation preview (the issued token carries an act claim naming the actor), and the legacy
fields of V1.
from archipy.adapters.keycloak.adapters import KeycloakAdapter
from archipy.models.dtos.keycloak.token_exchange_dtos import KeycloakTokenExchangeRequestDTO
keycloak = KeycloakAdapter()
exchanged = keycloak.token_exchange(
KeycloakTokenExchangeRequestDTO(subject_token=access_token, audience="downstream-service"),
)
The older exchange_token(subject_token, requested_subject=..., audience=..., scope=...) stays available for simple
impersonation.
Server features
Delegation is a Keycloak preview feature, and the legacy fields need the legacy exchange feature on the server. Enable them in Keycloak before relying on them.
JWT Bearer Grant¶
jwt_bearer_grant sends an assertion JWT to the token endpoint (RFC 7523). ID-JAG (identity assertion authorization
grant) and chaining across domains are two separate primitives: use token_exchange to obtain the assertion at the
first domain, then jwt_bearer_grant to redeem it at the second.
assertion = keycloak.token_exchange(
KeycloakTokenExchangeRequestDTO(
subject_token=access_token,
audience="https://keycloak.example.com/realms/domainb",
scope="access-domainb",
),
).access_token
token = second_domain_keycloak.jwt_bearer_grant(assertion, scope="profile")
The token returned by the second realm has no refresh token. The client must be confidential and allowed to use the identity provider that represents the first realm.
RPT Requests¶
request_rpt asks the token endpoint for a requesting party token (RPT) that carries the permissions the policies
grant to the given access token.
AuthZEN¶
Experimental
AuthZEN needs the server authzen feature enabled. Keycloak requires the resource type in practice, so always
set it.
get_authzen_configuration reads the discovery document. authzen_evaluation answers one access question and
authzen_evaluations answers several in one call.
from archipy.models.dtos.keycloak.authzen_dtos import (
KeycloakAuthzenActionDTO,
KeycloakAuthzenEvaluationRequestDTO,
KeycloakAuthzenResourceDTO,
KeycloakAuthzenSubjectDTO,
)
config = keycloak.get_authzen_configuration()
decision = keycloak.authzen_evaluation(
client_access_token, # a token issued to a client with authorization enabled
KeycloakAuthzenEvaluationRequestDTO(
subject=KeycloakAuthzenSubjectDTO(type="user", id="alice"),
resource=KeycloakAuthzenResourceDTO(type="document", id="quarterly-report"),
action=KeycloakAuthzenActionDTO(name="read"),
),
)
print(decision.decision)
authzen_evaluations(token, KeycloakAuthzenEvaluationsRequestDTO(...)) takes the same token and a batch whose top-level
subject, resource, action and context are defaults for each entry in evaluations.
The request and response DTOs live in archipy.models.dtos.keycloak.authzen_dtos.
Create Results and Ids¶
Keycloak answers creates with an empty body. Calls that return KeycloakCreateResultDTO look the new resource up, so
result.id is set when the adapter can find it. With skip_exists=True an existing resource gives
msg == "Already exists" and id is None. Updates, deletes and assignments return KeycloakUpdateResultDTO,
KeycloakDeleteResultDTO and KeycloakAssignResultDTO. All four live in archipy.models.dtos.keycloak.common_dtos.
result = keycloak.create_identity_provider(identity_provider_request)
if result.id is None:
logger.info("Provider skipped: %s", result.msg)
Deprecated: dicts
Dict payloads and dict-style reads (result["id"], result.get("id")) still work but emit a DeprecationWarning.
They are removed in 6.0.0. Use the request DTOs and the attributes of the response DTOs.
Error Mapping¶
The adapter maps Keycloak failures to ArchiPy errors, chained with from. A 404 raises ResourceNotFoundError,
bad credentials raise InvalidCredentialsError, and a forbidden call raises InsufficientPermissionsError.
from archipy.models.errors import ResourceNotFoundError
try:
keycloak.get_organization("missing-id")
except ResourceNotFoundError:
logger.warning("Organization does not exist")
Not Supported¶
The adapter does not wrap these Keycloak endpoints:
- Workflows: the server answers with YAML.
- Endpoints with
text/plain, multipart or form-encoded bodies: credential label, localization of a single text, the client description converter, certificate upload, and the organizationinvite-userandinvite-existing-usercalls.
Caching¶
Both adapters use TTL (Time-To-Live) caching for appropriate operations to improve performance. Cache durations are configured for each method based on how frequently the data typically changes:
- Public keys and certificate information: 1 hour
- User information from tokens: 30 seconds
- User details and role information: 5 minutes
Note
Token validation is never cached. Write operations such as user creation and updates clear the relevant caches.
You can clear all caches if needed:
Security Considerations¶
Warning
KEYCLOAK__REMOTE_CACHE_TTL_SECONDS trades freshness for fewer Keycloak calls. While it is set above 0, a revoked
token or a changed permission stays accepted until the cached entry expires.
- Token validation is performed without caching to ensure security.
- The adapter automatically refreshes admin tokens before they expire.
- Write operations (like user creation/updates) automatically clear relevant caches.
- For production use, prefer the authorization code flow over direct username/password authentication.
- The auth guards' role checks read
realm_accessandresource_accessfrom the UserInfo response. Stock Keycloak omits them there, so enable "Add to userinfo" on the realm roles and client roles mappers of therolesclient scope. - Token expiry is checked locally with
KEYCLOAK__TOKEN_LEEWAY_SECONDS(default0) of clock-skew tolerance; raise it only if your servers' clocks drift. - The auth guards call Keycloak for UserInfo (and UMA permissions) on every request. Set
KEYCLOAK__REMOTE_CACHE_TTL_SECONDSto a few seconds to cache those lookups per access token. A revoked token or a changed permission then stays accepted for up to that long, so it is off (0) by default.clear_keycloak_remote_cache()drops the cache.
