Evaluates the match conditions and mints an OAuth access token for the resolved target, scoped to a single workspace where the rule is enabled (chosen by the caller at exchange time when the rule is enabled for more than one). For rules enabled via workspace_ids or applies_to_all_workspaces, the target service account must be a member of that workspace (it is implicitly a member of the default workspace); rules carrying only the legacy workspace_id binding do not enforce this.

beta_federation_rule_match: object{ audience, claims, condition, subject_prefix }

Does the incoming JWT qualify?

All populated fields must pass; omitted fields are skipped. At least one of subject_prefix (other than a wildcard-only value like *), claims, or condition is required; audience alone is not sufficient.

audience: optional string

Exact match against the aud claim (any element if array). When omitted, the JWT's aud must still equal Anthropic's expected audience for the issuer; setting this field overrides that default.

maxLength1024

claims: optional map[string]

Exact-match {claim: value} pairs against top-level claims. Only string-valued claims can be matched; use condition for non-string claims.

condition: optional string

CEL expression over claims for logic the structural fields can't express. Must evaluate to a boolean and may reference only the claims variable; a constant-true expression (such as true) is rejected with 400.

maxLength4096

subject_prefix: optional string

Match the verified JWT sub claim. Exact match unless the value ends with *, in which case it is a prefix match. Example: repo:my-org/my-repo:ref:refs/heads/main.

maxLength1024
