https://www.theregister.com/2024/07/09/users_rage_as_microsoft_announces/ is also related. Less then 3 months until they drop the functionality seems far too short of a period.

to clearify:

• will break at October 1st, 2024
• can't create new endpoints at August 15th, 2024

Update from microsoft:

Update 07/17/2024: Due to customer feedback received around the footer message, it will be removed from the cards that are posted within Microsoft Teams.

It will still break, just not show the error warning any more

Deprecation was extended to December 2025 with a URL change, otherwise December 2024.

If other system administrators are having difficulties locating the affected teams:
I have written a small tool in Golang that uses the Graph API to output the affected teams.

Teams Webhook Finder

This has helped us enormously, as Microsoft does not offer its own solution for reading the affected channels and teams. We have over 350 teams in our company, which we would otherwise have had to search through manually.

There is also a neat Powershell Script which could list also other Connectors in Teams:

Teams Webhook Finder

That is correct. However, there are various dependencies. Modules must be installed and PowerShell is also required. With the Teams Webhook Finder, all I have is a small config and an executable file.
In addition, the cmdlets used to list the app definitions are only in preview, which does not guarantee a reliable application.

You can create a new webhook in workflow, and it seems that the API is the same, they just added the permission control.
