142142### Acquire and use the token

144At runtime your workload fetches its Entra token, exchanges it at `POST /v1/oauth/token`, and uses the returned bearer token to call Claude. Each Anthropic SDK handles the exchange and refresh loop when you supply a token-provider callable, as shown in the following examples. The cURL tab shows the raw flow.

Each Anthropic SDK handles the exchange and refresh loop when you supply `identity_token_provider` (typescript, php: `identityTokenProvider`; csharp: `IdentityTokenProvider`; go: `option.WithFederationTokenProvider`; java: `federationTokenProvider`), as shown in the following examples. The cURL tab shows the raw flow.

146146The samples fetch the managed identity token from the platform's token endpoint: IMDS on VMs and VM Scale Sets, or the `IDENTITY_ENDPOINT` service on App Service, Functions, and Container Apps. Replace `<APP_ID>` in the `api://<APP_ID>` resource value with the audience app registration's client ID from [Register the token audience](https://platform.claude.com/docs/en/manage-claude/wif-providers/azure#register-the-token-audience).

149 If your workload already uses the Azure Identity client library, pass its token acquisition (`DefaultAzureCredential` with the scope `api://<APP_ID>/.default`) as the identity token provider instead of calling the token endpoints directly. The library selects the correct endpoint on every Azure platform, including AKS with Entra Workload Identity.

764At runtime the pod performs the two-hop exchange: it sends the Kubernetes-projected token (the file at `AZURE_FEDERATED_TOKEN_FILE`) to Entra's token endpoint as a federated `client_credentials` assertion, then exchanges the resulting Entra access token at `POST /v1/oauth/token`. Each Anthropic SDK handles the second exchange and the refresh loop when you supply the Entra fetch as a token-provider callable, as shown in the following examples. The cURL tab shows the raw flow.

766766Two different client IDs appear in the samples. `<APP_ID>` is the audience app registration's client ID from [Register the token audience](https://platform.claude.com/docs/en/manage-claude/wif-providers/azure#register-the-token-audience); the scope `api://<APP_ID>/.default` asks Entra for a token addressed to that audience. `$AZURE_CLIENT_ID` is the managed identity's client ID, injected by the webhook, and identifies the caller. Do not substitute one for the other.

769 If your workload already uses the Azure Identity client library, pass its token acquisition (`DefaultAzureCredential` with the scope `api://<APP_ID>/.default`) as the identity token provider instead of performing the two-hop exchange yourself. The library reads the same `AZURE_FEDERATED_TOKEN_FILE`, `AZURE_CLIENT_ID`, and `AZURE_TENANT_ID` environment variables and handles the Entra exchange.
