Hi, I'm trying to create an integration to block certain URLs on Microsoft Defender with the Graph API.
After looking into the documentation, I found this endpoint: https://learn.microsoft.com/en-us/graph/api/tiindicators-post?view=graph-rest-beta&tabs=http, is it the correct one to use?
I also saw that tiindicators are deprecated, what is the new approach then?
thank you!

Based on our research the feasible way to manage Tenant Allow/Block List is by using PowerShell Scripts. This is documented here https://learn.microsoft.com/en-us/defender-office-365/tenant-allow-block-list-about.
The tiIndicator entity is deprecated and will be removed by April 2026. -

Is there another way (not specifically TreatIndicators) to pass applications\urls to Block on Microsoft Defender via API?
I want to be able to send a list of urls\domains from a web application via API to be blocked on Microsoft Defender.

It is a very simple yet key element to scale security response automation and processes and the current solution to rely on powershell script is very not convenient and not aligned with the global move to Graph API. -
