An incident is a collection of related alerts that help describe an attack. Events from different entities in your organization are automatically aggregated by Microsoft 365 Defender. You can use the incidents API to programatically access your organization’s incidents and related alerts.
Quotas and resource allocation
You can request up to 50 calls per minute or 1500 calls per hour. Each method also has its own quotas. For more information on method-specific quotas, see the respective article for the method you want to use.
