Generating an external login URL

1. Authenticate to the cloud platform via the Python shell.

   The following variables should be available now:

   >>> base_url  # the base URL of the API
   'https://eu2-cloud.acronis.com/api/2'
   >>> auth  # the 'Authorization' header value with the access token
   {'Authorization': 'Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsImtpZCI6ImMwMD...'}
   >>> tenant_id  # the UUID of the tenant to which the token provides access
   'ede9f834-70b3-476c-83d9-736f9f8c7dae'
   

2. Define a variable named ott_data, and then assign the one-time token data to this variable:

   >>> ott_data = {
   ...     "login": "johncustomer@mysite.com",
   ...     "purpose": "user_login",
   ... }
   

   Name	Value type	Required	Description
   login	string	Yes (if external_id and user_id are not specified)	User account login in the cloud platform.
   purpose	string	Yes	Purpose of the login. The only available option is user_login.
   external_id	string	Yes (if login and user_id are not specified)	External user account UUID (if the user was registered using available identity provider).
   user_id	UUID string	Yes (if login and external_id are not specified)	User account UUID in the cloud platform.

3. Convert the ott_data object to a JSON text:

   >>> ott_data = json.dumps(ott_data, indent=4)
   >>> print(ott_data)
   {
       "login": "johncustomer@mysite.com",
       "purpose": "user_login"
   }
   

4. Send a POST request with the JSON text to the /idp/ott endpoint:

   >>> response = requests.post(
   ...     f'{base_url}/idp/ott',
   ...     headers={'Content-Type': 'application/json', **auth},
   ...     data=ott_data,
   ... )
   

5. Check the status code of the response:

   >>> response.status_code
   200
   

   Status code 200 means that the token has been successfully issued.

   A different status code means that an error has occurred. For the details, refer to “Status and error codes”.

   Also, the response body contains the one-time token formatted as a JSON text. When converted to an object, it will look as follows:

   >>> pprint.pprint(response.json())
   {'ott': 'T1RUAQAAAG8-AAAAAAAATxLwKLZ0RMaVZ3GEk4JUMw=='}
   

   Important

   A one-time token can be used only once and it is valid for 30 seconds after it was generated.

6. Store the one-time token in a variable:

   >>> ott = response.json()['ott']
   

7. URL encode the one-time token:

   >>> from urllib.parse import quote
   >>> ott = quote(ott)
   

8. Define a variable and store a URL to which the user will be redirected. As an example, the backup console URL will be used:

   >>> target_uri = 'https://mc-beta-cloud.acronis.com/bc/'
   

9. The external login URL must lead to the /idp/external-login endpoint and contain ott and targetURI as query string parameters. Form the link using the variables above and open it to log in to the service:

   >>> sso_link = f'{base_url}/idp/external-login#ott={ott}&targetURI={target_uri}'
   >>> sso_link
   'https://mc-beta-cloud.acronis.com/api/2/idp/external-login#ott=T1RUAQAAAG8-AAAAAAAATxLwKLZ0RMaVZ3GEk4JUMw%3D%3D&targetURI=https://mc-beta-cloud.acronis.com/bc/'
