# Auth0 Vault Connection
## Get access to Auth0 Management API
[Create a Machine-to-Machine (M2M) Application](/docs/get-started/auth0-overview/create-applications/machine-to-machine-apps) authorized for Auth0 Management API.
Remember to authorize your M2M Application to access the Management API and select the right scopes following the Least Privilege Principle:
* For Get User: `read:users`
* For Create User: `create:users`
* For Update User: `update:users`
No need for Auth0 Management API authorization to send notifications through the configured providers at your Auth0 Tenant.
## Configure your Vault Connection
To configure an Auth0 Vault Connection for your Auth0 Flow Actions, set the required parameters based on the previous created M2M Application.
