Keycloak Admin API Reference

Authentication

# Get admin access token
TOKEN=$(curl -X POST "http://localhost:8080/realms/master/protocol/openid-connect/token" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "username=admin" \
  -d "password=admin" \
  -d "grant_type=password" \
  -d "client_id=admin-cli" | jq -r '.access_token')

Common API Endpoints

Realms:

• GET /admin/realms - List all realms
• POST /admin/realms - Create realm
• GET /admin/realms/{realm} - Get realm details
• PUT /admin/realms/{realm} - Update realm
• DELETE /admin/realms/{realm} - Delete realm

Users:

• GET /admin/realms/{realm}/users - List users
• POST /admin/realms/{realm}/users - Create user
• GET /admin/realms/{realm}/users/{id} - Get user
• PUT /admin/realms/{realm}/users/{id} - Update user

Multi-Tenant Configuration

Organization Claims Setup

For multi-tenant architecture, users MUST have organization claims:

{
  "org_id": "uuid-of-organization",
  "org_name": "Organization Display Name",
  "org_roles": ["admin", "member"],
  "org_permissions": ["read:data", "write:data"]
}

Implementation Steps:

1. Create custom user attributes:

   • org_id (required, UUID)
   • org_name (required, string)
   • org_roles (array of strings)
   • org_permissions (array of strings)

2. Create protocol mappers for each client:

   • Mapper Type: User Attribute
   • User Attribute: org_id
   • Token Claim Name: org_id
   • Claim JSON Type: String
   • Add to ID token: ON
   • Add to access token: ON
   • Add to userinfo: ON

3. Configure client scopes to include organization claims in all tokens

Theme Deployment Procedures

Theme Directory Structure

keycloak/themes/lobbi-theme/
├── login/
│   ├── theme.properties
│   ├── resources/
│   │   ├── css/
│   │   ├── js/
│   │   └── img/
│   └── *.ftl (FreeMarker templates)
├── account/
│   └── (same structure)
└── admin/
    └── (same structure)

Deployment Steps

1. Copy theme to Keycloak container:

   docker cp ./keycloak/themes/lobbi-theme keycloak:/opt/keycloak/themes/
   

2. Set theme in realm configuration:

   curl -X PUT "http://localhost:8080/admin/realms/{realm}" \
     -H "Authorization: Bearer $TOKEN" \
     -H "Content-Type: application/json" \
     -d '{
       "loginTheme": "lobbi-theme",
       "accountTheme": "lobbi-theme",
       "adminTheme": "lobbi-theme"
     }'
   

3. Clear Keycloak cache (if needed):

   docker exec keycloak /opt/keycloak/bin/kc.sh build
   docker restart keycloak
   

Common Issues and Remediation

Issue: Realm Creation Fails

Symptoms: 400 Bad Request when creating realm Diagnosis:

• Check realm name format (lowercase, no spaces)
• Verify admin token is valid
• Check JSON payload structure

Remediation:

# Validate token expiration
echo $TOKEN | cut -d '.' -f 2 | base64 -d | jq '.exp'

# Verify realm name constraints
[[ "$REALM_NAME" =~ ^[a-z0-9-]+$ ]] || echo "Invalid realm name"

Issue: User Creation with Organization Claims

Symptoms: Claims not appearing in token Diagnosis:

• Check user attributes are set
• Verify protocol mappers exist
• Confirm client scopes include mappers

Remediation:

# Verify user attributes
curl -X GET "http://localhost:8080/admin/realms/{realm}/users/{id}" \
  -H "Authorization: Bearer $TOKEN" | jq '.attributes'

# Check protocol mappers
curl -X GET "http://localhost:8080/admin/realms/{realm}/clients/{id}/protocol-mappers/models" \
  -H "Authorization: Bearer $TOKEN" | jq '.[] | select(.name | contains("org"))'

Issue: Theme Not Applied

Symptoms: Default Keycloak theme still showing Diagnosis:

• Theme files not copied to container
• Theme name mismatch in realm config
• Cache not cleared

Remediation:

# Verify theme files exist
docker exec keycloak ls -la /opt/keycloak/themes/lobbi-theme

# Check realm theme configuration
curl -X GET "http://localhost:8080/admin/realms/{realm}" \
  -H "Authorization: Bearer $TOKEN" | jq '{loginTheme, accountTheme, adminTheme}'

# Force rebuild and restart
docker exec keycloak /opt/keycloak/bin/kc.sh build && docker restart keycloak

Issue: CORS Errors

Symptoms: Browser console shows CORS policy errors Diagnosis:

• Client Web Origins not configured
• Redirect URIs missing
• Invalid origin pattern

Remediation:

# Update client CORS settings
curl -X PUT "http://localhost:8080/admin/realms/{realm}/clients/{id}" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "webOrigins": [
      "http://localhost:3000",
      "http://localhost:3001",
      "https://*.lobbi.app"
    ],
    "redirectUris": [
      "http://localhost:3000/*",
      "https://*.lobbi.app/*"
    ]
  }'

Best Practices

1. Security:

   • Never commit Keycloak admin credentials to Git
   • Use environment variables for secrets
   • Rotate admin passwords regularly
   • Enable HTTPS in production
   • Configure proper CORS policies

2. Multi-Tenancy:

   • Always add org_id to user attributes
   • Create protocol mappers for all clients
   • Validate organization claims in backend services
   • Use realm groups for organization management

3. Performance:

   • Enable token caching where appropriate
   • Set reasonable token expiration times (access: 5min, refresh: 30min)
   • Use client credentials flow for service-to-service auth
   • Monitor Keycloak metrics and logs

4. Maintenance:

   • Export realm configurations before major changes
   • Test theme changes in dev environment first
   • Document custom configurations
   • Keep Keycloak version up to date

Example Workflows

Create Multi-Tenant Realm

# 1. Get admin token
TOKEN=$(curl -X POST "http://localhost:8080/realms/master/protocol/openid-connect/token" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "username=admin" \
  -d "password=admin" \
  -d "grant_type=password" \
  -d "client_id=admin-cli" | jq -r '.access_token')

# 2. Create realm
curl -X POST "http://localhost:8080/admin/realms" \
  -H "Authorization: Bearer $TOKEN" \

# 4. Create organization claim mappers
curl -X POST "http://localhost:8080/admin/realms/lobbi-org/clients/$CLIENT_ID/protocol-mappers/models" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "org_id",
    "protocol": "openid-connect",
    "protocolMapper": "oidc-usermodel-attribute-mapper",
    "config": {
      "user.attribute": "org_id",
      "claim.name": "org_id",

      "id.token.claim": "true",
      "access.token.claim": "true",
      "userinfo.token.claim": "true"
    }
  }'

Provision User with Organization Claims

# 1. Create user
USER_ID=$(curl -X POST "http://localhost:8080/admin/realms/lobbi-org/users" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "username": "john.doe@example.com",
    "email": "john.doe@example.com",
    "enabled": true,
    "emailVerified": true,
    "firstName": "John",
    "lastName": "Doe",
    "attributes": {
      "org_id": ["123e4567-e89b-12d3-a456-426614174000"],
      "org_name": ["Acme Corporation"],
      "org_roles": ["admin", "member"]
    }
  }' | jq -r '.id')

# 2. Set password
curl -X PUT "http://localhost:8080/admin/realms/lobbi-org/users/$USER_ID/reset-password" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "type": "password",
    "value": "SecurePassword123!",
    "temporary": false
  }'

# 3. Assign realm role
curl -X POST "http://localhost:8080/admin/realms/lobbi-org/users/$USER_ID/role-mappings/realm" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '[{
    "name": "admin"
  }]'

• Edit: Modify existing theme files, configuration JSON, shell scripts
• Grep: Search for specific configurations, user attributes, client settings
• Glob: Find all theme files, configuration files, or client definitions
• WebFetch: Retrieve Keycloak documentation, version-specific API specs

Output Format

When completing tasks, provide:

1. Summary: What was accomplished
2. Commands Used: Full curl commands or scripts executed
3. Verification Steps: How to verify the changes worked
