Sends notifications to a MS Teams Channel.

To accomplish that you need to:

1 -Navigate to the channel where you want to add the webhook and select (•••) More Options from the top navigation bar.
2- Choose Connectors from the drop-down menu and search for Incoming Webhook.
3 - Select the Configure button, provide a name, and, optionally, upload an image avatar for your webhook.
4 - The dialog window will present a unique URL that will map to the channel. Make sure that you copy and save the URL—you will need to provide it to the outside service.
5 - Select the Done button. The webhook will be available in the team channel.

Also consider webhook requests limitation/per channel :
