Every request to the Virtus Cloud REST API must be authenticated. Virtus Cloud uses API key authentication — you include your key in the Authorization header of each HTTP request. There are no bearer token prefixes or OAuth flows to configure; simply pass the raw key and you are ready to make calls.

​
Get your API key

You can generate and manage your API keys from the Security page in your Virtus Cloud account dashboard. Navigate to Account → Security and create a new key. Treat your API key like a password — do not commit it to source control or share it publicly.
Rotate your API key immediately if you believe it has been compromised. Any requests made with a leaked key will count against your rate limit and may incur charges on your account.

​
Pass the key in the Authorization header

Include your API key as the value of the Authorization header on every request. No prefix (such as Bearer) is required. 
Authorization: <your_api_key>

​
Example request

The following example retrieves information about an application. Replace <your_api_key> with your actual key and <app_id> with the target application’s ID. 
curl --request GET \
  --url https://api.virtuscloud.app/v2/apps/<app_id> \
  --header "Authorization: <your_api_key>"
