--- layout: api page_title: Azure - Auth Methods - HTTP API description: |- This is the API documentation for the Vault Azure authentication method plugin. --- # Azure Auth Method (API) This is the API documentation for the Vault Azure auth method plugin. To learn more about the usage and operation, see the [Vault Azure method documentation](/docs/auth/azure). This documentation assumes the plugin method is mounted at the `/auth/azure` path in Vault. Since it is possible to enable auth methods at any location, please update your API calls accordingly. ## Configure Configures the credentials required for the plugin to perform API calls to Azure. These credentials will be used to query the metadata about the virtual machine. | Method | Path | | :----- | :------------------- | | `POST` | `/auth/azure/config` | ### Parameters - `tenant_id` `(string: )` - The tenant id for the Azure Active Directory organization. This value can also be provided with the `AZURE_TENANT_ID` environment variable. - `resource` `(string: )` - The resource URL for the application registered in Azure Active Directory. The value is expected to match the audience (`aud` claim) of the [JWT](/api-docs/auth/azure#jwt) provided to the login API. See the [resource](https://docs.microsoft.com/en-us/azure/active-directory/managed-identities-azure-resources/how-to-use-vm-token#get-a-token-using-http) parameter for how the audience is set when requesting a JWT access token from the Azure Instance Metadata Service (IMDS) endpoint. This value can also be provided with the `AZURE_AD_RESOURCE` environment variable. - `environment` `(string: 'AzurePublicCloud')` - The Azure cloud environment. Valid values: AzurePublicCloud, AzureUSGovernmentCloud, AzureChinaCloud, AzureGermanCloud. This value can also be provided with the `AZURE_ENVIRONMENT` environment variable. - `client_id` `(string: '')` - The client id for credentials to query the Azure APIs. Currently read permissions to query compute resources are required. This value can also be provided with the `AZURE_CLIENT_ID` environment variable. - `client_secret` `(string: '')` - The client secret for credentials to query the Azure APIs. This value can also be provided with the `AZURE_CLIENT_SECRET` environment variable. ### Sample Payload ```json { "tenant_id": "kd83...", "resource": "https://management.azure.com/", "client_id": "12ud...", "client_secret": "DUJDS3..." } ``` ### Sample Request ```shell-session $ curl \ --header "X-Vault-Token: ..." \ --request POST \ --data @payload.json \ https://127.0.0.1:8200/v1/auth/azure/config ``` # Read Config Returns the previously configured config, including credentials. | Method | Path | | :----- | :------------------- | | `GET` | `/auth/azure/config` | ### Sample Request ```shell-session $ curl \ --header "X-Vault-Token: ..." \ https://127.0.0.1:8200/v1/auth/azure/config ``` ### Sample Response ```json { "data":{ "tenant_id": "kd83...", "resource": "https://management.azure.com/", "client_id": "12ud...", "client_secret": "DUJDS3..." }, ... } ``` ## Delete Config Deletes the previously configured Azure config and credentials. | Method | Path | | :------- | :------------------- | | `DELETE` | `/auth/azure/config` | ### Sample Request ```shell-session $ curl \ --header "X-Vault-Token: ..." \ --request DELETE \ https://127.0.0.1:8200/v1/auth/azure/config ``` ## Create Role Registers a role in the method. Role types have specific entities that can perform login operations against this endpoint. Constraints specific to the role type must be set on the role. These are applied to the authenticated entities attempting to login. | Method | Path | | :----- | :----------------------- | | `POST` | `/auth/azure/role/:name` | ### Parameters - `name` `(string: )` - Name of the role. - `bound_service_principal_ids` `(array: [])` - The list of Service Principal IDs that login is restricted to. - `bound_group_ids` `(array: [])` - The list of group ids that login is restricted to. - `bound_locations` `(array: [])` - The list of locations that login is restricted to. - `bound_subscription_ids` `(array: [])` - The list of subscription IDs that login is restricted to. - `bound_resource_groups` `(array: [])` - The list of resource groups that login is restricted to. - `bound_scale_sets` `(array: [])` - The list of scale set names that the login is restricted to. @include 'tokenfields.mdx' ### Sample Payload ```json { "token_policies": ["default", "dev", "prod"], "max_ttl": 1800000, "max_jwt_exp": 10000, "bound_resource_groups": ["vault-dev", "vault-staging", "vault-prod"] } ``` ### Sample Request ```shell-session $ curl \ --header "X-Vault-Token: ..." \ --request POST \ --data @payload.json \ https://127.0.0.1:8200/v1/auth/azure/role/dev-role ``` ## Read Role Returns the previously registered role configuration. | Method | Path | | :----- | :----------------------- | | `GET` | `/auth/azure/role/:name` | ### Parameters - `name` `(string: )` - Name of the role. ### Sample Request ```shell-session $ curl \ --header "X-Vault-Token: ..." \ https://127.0.0.1:8200/v1/auth/azure/role/dev-role ``` ### Sample Response ```json { "data":{ "token_policies": [ "default", "dev", "prod" ], "max_ttl": 1800000, "max_jwt_exp": 10000, "bound_resource_groups": [ "vault-dev", "vault-staging", "vault-prod" ] }, ... } ``` ## List Roles Lists all the roles that are registered with the plugin. | Method | Path | | :----- | :----------------- | | `LIST` | `/auth/azure/role` | ### Sample Request ```shell-session $ curl \ --header "X-Vault-Token: ..." \ --request LIST \ https://127.0.0.1:8200/v1/auth/azure/role ``` ### Sample Response ```json { "data": { "keys": [ "dev-role", "prod-role" ] }, ... } ``` ## Delete Role Deletes the previously registered role. | Method | Path | | :------- | :----------------------- | | `DELETE` | `/auth/azure/role/:name` | ### Parameters - `name` `(string: )` - Name of the role. ### Sample Request ```shell-session $ curl \ --header "X-Vault-Token: ..." \ --request DELETE \ https://127.0.0.1:8200/v1/auth/azure/role/dev-role ``` ## Login Fetch a token. This endpoint takes a signed JSON Web Token (JWT) and a role name for some entity. It verifies the JWT signature to authenticate that entity and then authorizes the entity for the given role. | Method | Path | | :----- | :------------------ | | `POST` | `/auth/azure/login` | ### Sample Payload - `role` `(string: )` - Name of the role against which the login is being attempted. - `jwt` `(string: )` - Signed [JSON Web Token](https://tools.ietf.org/html/rfc7519) (JWT) from Azure MSI.

This information can be obtained through instance metadata. - `resource_group_name` `(string: )` - The resource group for the machine that generated the MSI token. This information can be obtained through instance metadata. - `vm_name` `(string: "")` - The virtual machine name for the machine that generated the MSI token. This information can be obtained through instance metadata. If vmss_name is provided, this value is ignored. - `vmss_name` `(string: "")` - The virtual machine scale set name for the machine that generated the MSI token. This information can be obtained through instance metadata. ### Sample Payload ```json { "role": "dev-role", "jwt": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..." } ``` ### Sample Request ```shell-session $ curl \ --request POST \ --data @payload.json \ https://127.0.0.1:8200/v1/auth/azure/login ``` ### Sample Response ```json { "auth":{ "client_token":"f33f8c72-924e-11f8-cb43-ac59d697597c", "accessor":"0e9e354a-520f-df04-6867-ee81cae3d42d", "token_policies":[ "default", "dev", "prod" ], "lease_duration":2764800, "renewable":true }, ... } ```
