# 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](/vault/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: <required>)` - The tenant id for the Azure Active Directory organization.
  This value can also be provided with the `AZURE_TENANT_ID` environment variable.
- `resource` `(string: <required>)` - The resource URL for the application registered in Azure Active Directory.
  The value is expected to match the audience (`aud` claim) of the [JWT](/vault/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.
- `max_retries` `(int: 3)` - The maximum number of attempts a failed operation will be 
  retried before producing an error.
- `max_retry_delay` `(string: '60s')` - The maximum delay, in seconds, allowed before retrying an operation.
- `retry_delay` `(string: '4s')` - The initial amount of delay, in seconds, to use before retrying an operation. Increases exponentially.

  generated the MSI token. This information can be obtained through instance
  metadata.
