This article describes how to interact with Defender for Cloud Apps over HTTPS.

The Microsoft Defender for Cloud Apps API provides programmatic access to Defender for Cloud Apps through REST API endpoints. Applications can use the API to perform read and update operations on Defender for Cloud Apps data and objects. For example, the Defender for Cloud Apps API supports the following common operations for a user object:

Upload log files for cloud discovery
Generate block scripts
List activities and alerts
Dismiss or resolve alerts

API URL structure

To use the Defender for Cloud Apps API, you must first obtain the API URL from your tenant. The API URL uses the following format: https://<portal_url>/api/<endpoint>.

To obtain the Defender for Cloud Apps API URL for your tenant, do the following steps:

In the Microsoft Defender Portal, select Settings. Then choose Cloud Apps. Under System, select About.
In the Defender for Cloud Apps about screen, you can see the API url.

Once you have the API url, add the /api suffix to it to obtain your API URL. For example, if your portal's URL is https://mytenant.us2.contoso.com, then your API URL is https://mytenant.us2.portal.cloudappsecurity.com/api.

API tokens

Defender for Cloud Apps requires an API token in the header of all API requests to the server, such as the following:

Authorization: Token <your_token_key>

Where <your_token_key> is your personal API token.

For more information about API tokens, see Managing API tokens.

Mentions of timestamps in the Defender for Cloud Apps API refer to the Unix timestamp in milliseconds. This timestamp is determined by the number of milliseconds since 1970-01-01 0:00:00. You can use the get-date PowerShell cmdlet to convert dates to timestamps.

You can choose to limit your requests by providing a limit parameter in the request.

The following methods are supported for providing the limit parameter:

URL-encoded (with Content-Type: application/x-www-form-urlencoded header)
Form data
JSON body (with Content-Type: multipart/form-data and an appropriate boundary header)

Note

If no limit is provided, a default of 100 will be set.
Responses for all requests made with the API token are limited to a maximum of 100 items.
The throttle limit for all API requests is 30 requests per minute per tenant.

Filters

When you have a large number of results, you'll find it useful to fine-tune requests using filters. This section describes the structure of, and operators that can be used with, filters.

Structure

Some of our API endpoints support filters when performing queries. In their relevant sections, you will find a reference listing all available filterable fields and supported operators for that resource.

Most filters support multiple values to provide you with powerful queries. When combining filters and operators we use AND as the logical operator between the filters.

Filters - example

curl -XGET -H "Authorization:Token <your_token_key>" "https://<tenant_id>.<tenant_region>.portal.cloudappsecurity.com/api/example-endpoint" -d '{
  "filters": {
    "some.field": {
      "eq": ["value1", "value2"],
      "isset": true
    },
    "some.field2": {
      "gte": 5
    }
  },
  "skip": 5,
  "limit": 10
}'
