77**Federation rule:** Match the audience you pass to `GetWebIdentityToken` and the calling role’s IAM role ARN in the `sub` claim. The `sub` value is the IAM role ARN of the workload that called the API, in the form `arn:aws:iam::<account>:role/<role-name>`. The token also carries an `https://sts.amazonaws.com/` claim with `aws_account`, `org_id`, `principal_id`, and any `request_tags` you passed; you can match on those with the rule’s `claims` map or a CEL `condition` for finer control.

98Call `GetWebIdentityToken` with `https://api.anthropic.com` as the audience, then pass the result to the SDK’s federation credentials through `identity_token_provider` (typescript: `identityTokenProvider`; php: `identityProvider`; csharp: `IdentityTokenProvider`; go: `option.WithFederationTokenProvider()`; java: `IdentityTokenConfig`). Except in Java (see the comment in that example), that option takes a token provider, so the SDK calls STS again on each refresh.

101101 `GetWebIdentityToken` is available only on regional STS endpoints. If you receive `'STS' object has no attribute 'get_web_identity_token'` or a similar error, pin your STS client to a region (for example, `boto3.client("sts", region_name="us-east-1")`) and ensure your AWS SDK is recent enough to include the API.
