/json/token/macaroon

The /json/token/macaroon endpoint lets you inspect and manipulate macaroon tokens.

Specify the realm in the request URL; for example:

https://openam.example.com:8443/openam/oauth2/realms/root/realms/alpha/token/macaroon

This endpoint supports these parameters:

Field Description

action=inspect

Return details about the macaroon.

action=restrict

Add a caveat to the macaroon, returning a new macaroon.

You can manipulate macaroons locally using a macaroon library. Anyone in possession of a macaroon token can inspect and restrict the macaroon securely.

The following example restricts the scope of a macaroon token and inspects the result. The original scope of the unrestricted token is openid profile:

$ curl \
--request POST \
--header "Content-Type: application/json" \
--header "cache-control: no-cache" \
--data '{
  "macaroon": "<macaroon-token>",
  "caveat": {"type": "first-party", "identifier": {"scope": "profile"}}
}' \
'https://openam.example.com:8443/openam/json/realms/root/realms/alpha/token/macaroon?_action=restrict'
{
  "macaroon": "<restricted-macaroon-token>"
}

$ curl \
--request POST \
--header "Content-Type: application/json" \
--header "cache-control: no-cache" \
--data '{"macaroon": "<restricted-macaroon-token>"}' \
'https://openam.example.com:8443/openam/json/realms/root/realms/alpha/token/macaroon?_action=inspect'
{
  "identifier": "<identifier>",
  "location": "",
  "caveats": [{
    "type": "first-party",
    "identifier": {
      "scope": "profile"
    }
  }],
  "signature": "<signature>"
}

OIDC clients must ensure the following information is present in the JSON:

  • The openid scope; for example, "scopes": ["profile", "openid"].

  • The id_token response type; for example, "response_types": ["code", "id_token code"].
