Overview

The following topics will instruct you how to connect to the REST API and authorize your access, and how to control and sort the data that the REST API returns.

Resource URLs

Each Veeam Backup for Microsoft Azure REST API-exposed entity has a resource representing it. To get a resource representation, request its URL.

Veeam Backup for Microsoft Azure REST API Resource URLs

All Veeam Backup for Microsoft Azure REST API v8 requests use the following base URL format:

https://<hostname>/api/<version>

where:

  • <hostname> is a public IPv4 address or DNS hostname of the Azure VM running Veeam Backup for Microsoft Azure.

  • <version> is an API version.

    The current version is v8.

To get a collection of Veeam Backup for Microsoft Azure REST API resources, request a base URL followed by a resource collection endpoint.

https://51.11.247.127/api/v8/accounts/standard

To get a representation of an individual resource, enter a resource identifier after the resource collection endpoint.

https://51.11.247.127/api/v8/accounts/standard/543

The resource identifier is represented by the id property of the resource from the collection.

[
  {
    "name": "SMTP Account",
    "id": "543",
    ...
  }
]

Configuration Restore REST API Resource URLs

All Configuration Restore REST API v8 requests use the following base URL format:

https://<hostname>/api/restoreservice/<version>

where:

  • <hostname> is a public IPv4 address or DNS hostname of the Azure VM running Veeam Backup for Microsoft Azure.

  • <version> is an API version.

    The current version is v8.

Versioning

The Veeam Backup for Microsoft Azure REST API is available in multiple versions. The Veeam Backup for Microsoft Azure REST API is backward-compatible with client applications that were created using earlier versions of the REST API specification. This means that you can use any of the supported REST API specifications to perform operations with Veeam Backup for Microsoft Azure resources if the specification version has been released earlier or with the product version installed on the backup appliance:

Veeam Backup for Microsoft Azure 7.0

Veeam Backup for Microsoft Azure 6.0

Veeam Backup for Microsoft Azure 5a

Veeam Backup for Microsoft Azure 5.0

Veeam Backup for Microsoft Azure 4.0

Veeam Backup for Microsoft Azure 3.0

Veeam Backup for Microsoft Azure 2.0

v2

Authorization and Security

To start working with the Veeam Backup for Microsoft Azure REST API, users must first authenticate themselves and get authorization to make requests. Veeam Backup for Microsoft Azure REST API authorization process is based on the OAuth 2.0 Authorization Framework and involves obtaining an access token and a refresh token.

  • Access token is a string that represents authorization issued to the client and that must be used in all requests during the current logon session. By default, the Veeam Backup for Microsoft Azure access token expires in 60 minutes.
  • Refresh token is a string that represents authorization granted to the client and that can be used to obtain a new access token if the current access token expires or becomes lost. By default, refresh token expires in 14 days. If you want to change the expiration period to 15 minutes, set the short_lived_refresh_token parameter value to true.

For increased security, Veeam Backup for Microsoft Azure allows you to use multi-factor authentication (MFA) to verify user identity. It is recommended to enable MFA for Veeam Backup for Microsoft Azure users. For more information, see Multi-Factor Authentication or the Veeam Backup for Microsoft Azure User Guide, section Managing User Accounts.

Authorization in REST API

Veeam Backup for Microsoft Azure follows OAuth 2.0 protocol for authenticating and authorizing users in the REST API. The authorization process involves the following procedures:

  1. Requesting authorization.
  2. Using the refresh token.
  3. Performing logout.

Requesting Authorization

The Veeam Backup for Microsoft Azure REST API accepts several grant types to authenticate a Veeam Backup for Microsoft Azure user:

You can configure single sign-on (SSO) settings in Veeam Backup for Microsoft Azure and retrieve user identities from your identity provider. To authenticate a user retrieved from the identity provider, the Veeam Backup for Microsoft Azure REST API uses single sign-on authorization. For more information on configuring SSO settings, see the Configuring SSO Settings section of the Veeam Backup for Microsoft Azure User Guide.

Using Password Grant Type

To obtain authorization tokens, a user sends the HTTP POST request to the /oauth2/token endpoint.

The request body must contain the grant_type parameter with the specified Password value and the credentials of a user created in Veeam Backup for Microsoft Azure. For more information on how to create users, see Users or the Veeam Backup for Microsoft Azure, section Managing User Accounts.

A successfully completed operation returns the 200 response code. In the response body, Veeam Backup for Microsoft Azure returns an access token, its expiration time (in seconds) and a refresh token. The user inserts the access token in headers of further requests to the Veeam Backup for Microsoft Azure REST API. The refresh token must be saved locally.

To learn how to authorize your access using the Password grant type, see Example [Password]. Alternatively, you can use the Swagger UI.

Using MFA Grant Type

NOTE

MFA is disabled by default. To learn how to enable MFA, see Multi-Factor Authentication or the Veeam Backup for Microsoft Azure User Guide, section Enabling Multi-Factor Authentication.

If multi-factor authentication (MFA) is enabled for a user, the user must first obtain an mfa token, and then get authorization tokens.

  1. To obtain an mfa token, the user sends the HTTP POST request to the /oauth2/token endpoint. The request body must contain the grant_type parameter with the specified Password value and the credentials of the user.

    A successfully completed operation returns the 200 response code. In the response body, Veeam Backup for Microsoft Azure returns an mfa token.

  2. To obtain an access token and a refresh token, the user must send another HTTP POST request to the /v8/token endpoint. The request body must contain the grant_type parameter with the specified Mfa value, the mfa token previously received from the authorization server, and the verification code generated by an authentication application on the trusted device.

    A successfully completed operation returns the 200 response code. In the response body, Veeam Backup for Microsoft Azure returns an access token, its expiration time (in seconds) and a refresh token. The user inserts the access token in headers of further requests to the Veeam Backup for Microsoft Azure REST API. The refresh token must be saved locally.

To learn how to authorize your access using the MFA grant type, see Example [MFA]. Alternatively, you can use the Swagger UI.

Example [Password]

To obtain an access token and a refresh token, a user sends the HTTP POST request to the api/oauth2/token endpoint.

In the request body, the user specifies the following parameters:

  • grant_type — the Password value must be specified for this parameter.
  • Username and Password — credentials used to access the server; in this example, administrator and Password1 are used.
Request:
POST https://51.11.247.127/api/oauth2/token

Using Refresh Token

To obtain a new pair of tokens in case the access token expires or becomes lost, a user sends the HTTP POST request with the refresh token in the request body to the /oauth2/token endpoint. A successfully completed operation returns the 200 response code and a new pair of tokens in the response body.

TIP

If you lose the refresh token, you can log in again under the same user account and get a new pair of tokens.

Example

To obtain an access token and a refresh token, a user sends the HTTP POST request to the /oauth2/token endpoint.

In the body of the request, the user specifies the following parameters:

  • grant_type — to refresh the token, it is required that the Refresh_token value must be specified for this parameter.
  • refresh_token — the previously saved refresh token.
Request:
POST https://51.11.247.127/api/oauth2/token

Multi-Factor Authentication

Veeam Backup for Microsoft Azure multi-factor authentication (MFA) is based on the Time-based One-Time Password (TOTP) method. This method requires a user to install an application authentication on the trusted device. The authenticator application will generate temporary six-digit codes used to verify the user identity. Veeam Backup for Microsoft Azure supports Google Authenticator.

You can enable or disable MFA for a Veeam Backup for Microsoft Azure user using the REST API.

Enabling MFA

To enable MFA for a specific user, do the following:

  1. To obtain a secret key and a token, send the HTTP POST request to the /users/{id}/enableMfa endpoint.

    In the request body, specify the recreate parameter. The parameter indicates whether you want to re-create the existing MFA secret key (true) or to enable MFA for the user (false). Specify the false value for the parameter.

    Request:
POST https://51.11.247.127/api/v8/users/1423/enableMfa

Request Header:
Authorization: Bearer YSEoaL6H9EEyJpnrJ9WhLtzbrrBBYWqMQFDBQuLnp13qGQX6MjNfZ_wriPIRHQrbY-8dYtsWcRZQczIHVuSqbnVb00m-yOihPZZHQ48aP1VcgUtgnYTvtAO3WRJ1cJ...

Request Body:
{
   "recreate": "false"
}

    A successfully completed operation returns the 200 response code. In the response body, Veeam Backup for Microsoft Azure returns the secret key, token, recovery scratch codes and the qrString link. The recovery codes must be saved locally.

    Response:
200

Response Body:
{
   "userId": "administrator",
   "qrString": "otpauth://totp/administrator&40ip-172-31-71-115?secret=5XKNCVA54BPWQWCXLJZYLMIBD4&issuer=ip-172-31-71-115",
   "secretKey": "5XKNCVA54BPWQWCXLJZYLMIBD4",
   "scratchCodes": [
      "79529234",
      "99447341",
      "98474119",
      "94074142",
      "95269008"
   ],
   "token": "M0Q1OEMwOEQ5MTRFNzMwMzE5MTkzMUU5MDVCNjNENzREMTQ0MDYyRUJFNEE0QjI5MzEzNzVEMUE1QURFNzBENA=="
}

  2. Install Google Authenticator on the trusted device.

  3. Open Google Authenticator, create an account and enter the secret key manually.

    Google Authenticator will generate a six-digit verification code.

    TIP

    You can use a QR code to create an account in the authentication application:

    1. On another device, open a QR code generator in a web browser.

    2. In the QR code generator, insert the qrString link returned by Veeam Backup for Microsoft Azure. The QR code generator will display a QR code.

    3. On your trusted device, open Google Authenticator and choose the Scan barcode option.

    4. Scan the displayed QR code using the device camera.

      Google Authenticator will automatically create an account and generate a six-digit verification code.

  4. To associate the authentication application with the authorization server, send the HTTP POST request to the /users/{id}/acceptMfa endpoint.

    In the Authorization header — currently valid access token in the Bearer <access_token> format.

    In the request body, specify the following parameters:

    • code — the six-digit verification code generated by the authentication application on the trusted device.
    • token — the token previously received from the authorization server.
    Request:
POST https://51.11.247.127/api/v8/users/1423/acceptMfa

Request Header:
Authorization: Bearer YSEoaL6H9EEyJpnrJ9WhLtzbrrBBYWqMQFDBQuLnp13qGQX6MjNfZ_wriPIRHQrbY-8dYtsWcRZQczIHVuSqbnVb00m-yOihPZZHQ48aP1VcgUtgnYTv...

Request Body:

}

    A successfully completed operation returns the 204 response code.

    Response:
204
    NOTE

    In case of losing access to the authentication application:

    • To get authorization in Veeam Backup for Microsoft Azure, the user can use a recovery scratch code saved locally instead of a verification code. Each recovery code can be used only once.
    • To re-create the MFA secret key for a new device if the trusted device is lost or broken, repeat step 1 (specify the true value for the recreate parameter), and then repeat steps 2, 3 and 4.

Disabling MFA

To disable MFA for a specific user, send the HTTP POST request to the /users/{id}/disableMfa endpoint.

In the Authorization header specify the currently valid access token in the Bearer <access_token> format.

Request:
POST https://51.11.247.127/api/v8/users/1423/disableMfa

Request Header:
Authorization: Bearer YSEoaL6H9EEyJpnrJ9WhLtzbrrBBYWqMQFDBQuLnp13qGQX6MjNfZ_wriPIRHQrbY-8dYtsWcRZQczIHVuSqbnVb00m-yOihPZZHQ48aP1VcgUtgnYTvtAO3WRJ1cJ8VaIXzsVYKIGrL...

IMPORTANT

All query parameters are case-sensitive.

Query parameters are part of a URL. The question mark ? separates query parameters from a resource collection endpoint.

Offset Parameter

The Offset query parameter is used to exclude from a response the first N items of a resource collection.

For example, to return a list of Azure regions starting from the third one in the /regions collection, send the following request:

GET https://<hostname>/api/<version>/cloudInfrastructure/regions?Offset=2

You can combine the Limit and the Offset query parameters to request a particular set of items. Note that the Offset parameter is applied before the Limit parameter, regardless of the parameter position in the request. That is, top results are selected from a collection where a set of items is already excluded.

The Veeam Backup for Microsoft Azure REST API returns resources in the default order based on its own semantics. To filter a collection before excluding results, use the Filter or SearchPattern or one of the filter query parameters. Note that the SearchPattern and filter parameters are applied before the Offset parameter, regardless of their position in the request. That is, a collection is first filtered or sorted, and then the top results are excluded.

Limit Parameter

The Limit query parameter is used to specify the maximum number of items of a resource collection to return in a response.

For example, to return only the first 3 Azure VMs in the /virtualMachines collection, send the following request:

GET https://<hostname>/api/<version>/virtualMachines?Limit=3

The Veeam Backup for Microsoft Azure REST API returns resources in the default order based on its own semantics. To sort or filter a collection before excluding results, use the SearchPattern or one of the filter query parameters. Note that the Sort, SearchPattern and filter parameters are applied before the Limit parameter, regardless of their position in the request. That is, a collection is first filtered or sorted, and then the top results are selected.

SearchPattern Parameter

The SearchPattern query parameter is used to return only those items of a resource collection whose names match the specified search pattern in the parameter value.

For example, to get only Azure VMs whose name contains the ubuntu search pattern in the /virtualMachines collection, send the following request:

GET https://<hostname>/api/<version>/virtualMachines?SearchPattern=ubuntu

Filter Parameters

Some resource properties of Veeam Backup for Microsoft Azure REST API schemas can be used as filter query parameters. Filter query parameters are used to filter items of a resource collection to return a subset of resources in a response. The subset includes only those resources that satisfy parameter value specified in the query.

For example, to return a list of protected Azure VMs of the /virtualMachines collection, send the Protected value of the ProtectionStatus filter parameter in the following request:

GET https://<hostname>/api/<version>/virtualMachines?ProtectionStatus=Protected

Pagination

To increase readability and optimize network traffic, Veeam Backup for Microsoft Azure REST API applies pagination to a number of responses that contain array of values.

Pagination data is returned in the meta section of a response and includes the following properties:

  • offset — number of resources skipped. You can skip resources using the $offset parameter.
  • limit — number of resources on the current page. The default value is 100. You can modify this number using the $limit parameter.
  • totalCount — total number of resources returned.
NOTE

Veeam Backup for Microsoft Azure REST API returns resources in the default order based on its own semantics.
