Usage

Step 1. Setup Proxy

• JWT_PUBLIC_KEY_URL: This is the public keys endpoint of your OpenID provider. Typically it's {openid-provider-base-url}/.well-known/openid-configuration/jwks. For Keycloak it's {keycloak_base_url}/realms/{your-realm}/protocol/openid-connect/certs.
• JWT_AUDIENCE: This is the audience used for decoding the JWT. If not set, the decode step will not verify the audience.

export JWT_PUBLIC_KEY_URL="" # "https://demo.duendesoftware.com/.well-known/openid-configuration/jwks"

• enable_jwt_auth in your config. This will tell the proxy to check if a token is a jwt token.

general_settings:
  master_key: sk-1234
  enable_jwt_auth: True

model_list:
- model_name: azure-gpt-3.5 
  litellm_params:
      model: azure/<your-deployment-name>
      api_base: os.environ/AZURE_API_BASE
      api_key: os.environ/AZURE_API_KEY
      api_version: "2023-07-01-preview"

Step 2. Create JWT with scopes

admin

Create a client scope called litellm_proxy_admin in your OpenID provider (e.g. Keycloak).

Grant your user, litellm_proxy_admin scope when generating a JWT.

curl --location ' 'https://demo.duendesoftware.com/connect/token'' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'client_id={CLIENT_ID}' \
--data-urlencode 'client_secret={CLIENT_SECRET}' \
--data-urlencode 'username=test-{USERNAME}' \
--data-urlencode 'password={USER_PASSWORD}' \
--data-urlencode 'grant_type=password' \
--data-urlencode 'scope=litellm_proxy_admin' # 👈 grant this scope

project

Create a JWT for your project on your OpenID provider (e.g. Keycloak).

curl --location ' 'https://demo.duendesoftware.com/connect/token'' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'client_id={CLIENT_ID}' \ # 👈 project id
--data-urlencode 'client_secret={CLIENT_SECRET}' \
--data-urlencode 'grant_type=client_credential' \

Step 3. Test your JWT

/key/generate

curl --location '{proxy_base_url}/key/generate' \
--header 'Authorization: Bearer eyJhbGciOiJSUzI1NiI...' \
--header 'Content-Type: application/json' \
--data '{}'

/chat/completions

curl --location 'http://0.0.0.0:4000/v1/chat/completions' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer eyJhbGciOiJSUzI1...' \
--data '{"model": "azure-gpt-3.5", "messages": [ { "role": "user", "content": "What's the weather like in Boston today?" } ]}'

Advanced - Set Accepted JWT Scope Names

Change the string in JWT 'scopes', that litellm evaluates to see if a user has admin access.

general_settings:
  master_key: sk-1234
  enable_jwt_auth: True
  litellm_jwtauth:
    admin_jwt_scope: "litellm-proxy-admin"

Tracking End-Users / Internal Users / Team / Org

Set the field in the jwt token, which corresponds to a litellm user / team / org.

general_settings:
  master_key: sk-1234
  enable_jwt_auth: True
  litellm_jwtauth:
    admin_jwt_scope: "litellm-proxy-admin"
    team_id_jwt_field: "client_id" # 👈 CAN BE ANY FIELD
    user_id_jwt_field: "sub" # 👈 CAN BE ANY FIELD
    org_id_jwt_field: "org_id" # 👈 CAN BE ANY FIELD
    end_user_id_jwt_field: "customer_id" # 👈 CAN BE ANY FIELD

Expected JWT:

{
  "client_id": "my-unique-team",
  "sub": "my-unique-user",
  "org_id": "my-unique-org",
}

Now litellm will automatically update the spend for the user/team/org in the db for each call.

JWT Scopes

Here's what scopes on JWT-Auth tokens look like

Can be a list

scope: ["litellm-proxy-admin",...]

Can be a space-separated string

scope: "litellm-proxy-admin ..."

Control model access with Teams

1. Specify the JWT field that contains the team ids, that the user belongs to.

general_settings:
  master_key: sk-1234
  litellm_jwtauth:
    user_id_jwt_field: "sub"
    team_ids_jwt_field: "groups" 

This is assuming your token looks like this:

{
  ...,
  "sub": "my-unique-user",
  "groups": ["team_id_1", "team_id_2"]
}

2. Create the teams on LiteLLM

curl -X POST '<PROXY_BASE_URL>/team/new' \
-H 'Authorization: Bearer <PROXY_MASTER_KEY>' \
-H 'Content-Type: application/json' \
-D '{
    "team_alias": "team_1",
    "team_id": "team_id_1" # 👈 MUST BE THE SAME AS THE SSO GROUP ID
}'

3. Test the flow

SSO for UI: See Walkthrough

OIDC Auth for API: See Walkthrough

Flow

• Validate if user id is in the DB (LiteLLM_UserTable)
• Validate if any of the groups are in the DB (LiteLLM_TeamTable)
• Validate if any group has model access
• If all checks pass, allow the request

Advanced - Allowed Routes

Configure which routes a JWT can access via the config.

By default:

• Admins: can access only management routes (/team/*, /key/*, /user/*)
• Teams: can access only openai routes (/chat/completions, etc.)+ info routes (/*/info)

See Code

Admin Routes

general_settings:
  master_key: sk-1234
  enable_jwt_auth: True
  litellm_jwtauth:
    admin_jwt_scope: "litellm-proxy-admin"
    admin_allowed_routes: ["/v1/embeddings"]

Team Routes

general_settings:
  master_key: sk-1234
  enable_jwt_auth: True
  litellm_jwtauth:
    ...
    team_id_jwt_field: "litellm-team" # 👈 Set field in the JWT token that stores the team ID
    team_allowed_routes: ["/v1/chat/completions"] # 👈 Set accepted routes

Advanced - Caching Public Keys

Control how long public keys are cached for (in seconds).

general_settings:
  master_key: sk-1234
  enable_jwt_auth: True
  litellm_jwtauth:
    admin_jwt_scope: "litellm-proxy-admin"
    admin_allowed_routes: ["/v1/embeddings"]
    public_key_ttl: 600 # 👈 KEY CHANGE

Advanced - Custom JWT Field

Set a custom field in which the team_id exists. By default, the 'client_id' field is checked.

general_settings:
  master_key: sk-1234
  enable_jwt_auth: True
  litellm_jwtauth:
    team_id_jwt_field: "client_id" # 👈 KEY CHANGE

All Params

See Code

Advanced - Block Teams

To block all requests for a certain team id, use /team/block

Block Team

curl --location 'http://0.0.0.0:4000/team/block' \
--header 'Authorization: Bearer <admin-token>' \
--header 'Content-Type: application/json' \
--data '{
    "team_id": "litellm-test-client-id-new" # 👈 set team id
}'

Unblock Team

curl --location 'http://0.0.0.0:4000/team/unblock' \
--header 'Authorization: Bearer <admin-token>' \
--header 'Content-Type: application/json' \
--data '{
    "team_id": "litellm-test-client-id-new" # 👈 set team id
}'

Advanced - Upsert Users + Allowed Email Domains

Allow users who belong to a specific email domain, automatic access to the proxy.

general_settings:
  master_key: sk-1234
  enable_jwt_auth: True
  litellm_jwtauth:
    user_email_jwt_field: "email" # 👈 checks 'email' field in jwt payload
    user_allowed_email_domain: "my-co.com" # allows user@my-co.com to call proxy
    user_id_upsert: true # 👈 upserts the user to db, if valid email but not in db

[BETA] Control Access with OIDC Roles

Allow JWT tokens with supported roles to access the proxy.

Let users and teams access the proxy, without needing to add them to the DB.

Very important, set enforce_rbac: true to ensure that the RBAC system is enabled.

Note: This is in beta and might change unexpectedly.

general_settings:
  enable_jwt_auth: True
  litellm_jwtauth:
    object_id_jwt_field: "oid" # can be either user / team, inferred from the role mapping
    roles_jwt_field: "roles"
    role_mappings:
      - role: litellm.api.consumer
        internal_role: "team"
    enforce_rbac: true # 👈 VERY IMPORTANT

  role_permissions: # default model + endpoint permissions for a role. 
    - role: team
      models: ["anthropic-claude"]
      routes: ["/v1/chat/completions"]

environment_variables:
  JWT_AUDIENCE: "api://LiteLLM_Proxy" # ensures audience is validated

• object_id_jwt_field: The field in the JWT token that contains the object id. This id can be either a user id or a team id. Use this instead of user_id_jwt_field and team_id_jwt_field. If the same field could be both.

• roles_jwt_field: The field in the JWT token that contains the roles. This field is a list of roles that the user has. To index into a nested field, use dot notation - eg. resource_access.litellm-test-client-id.roles.

• role_mappings: A list of role mappings. Map the received role in the JWT token to an internal role on LiteLLM.

• JWT_AUDIENCE: The audience of the JWT token. This is used to validate the audience of the JWT token. Set via an environment variable.

Example Token

{
  "aud": "api://LiteLLM_Proxy",
  "oid": "eec236bd-0135-4b28-9354-8fc4032d543e",
  "roles": ["litellm.api.consumer"]
}

Role Mapping Spec

• role: The expected role in the JWT token.
• internal_role: The internal role on LiteLLM that will be used to control access.

Supported internal roles:

• team: Team object will be used for RBAC spend tracking. Use this for tracking spend for a 'use case'.
• internal_user: User object will be used for RBAC spend tracking. Use this for tracking spend for an 'individual user'.
• proxy_admin: Proxy admin will be used for RBAC spend tracking. Use this for granting admin access to a token.
