Slack and Microsoft Teams

A channel webhook of Slack or Teams

Slack and Teams channels need only the address of the channel’s webhook:

Type	Webhook address
Slack	The channel’s incoming webhook (Slack app > Incoming Webhooks).
Microsoft Teams	The channel’s Workflows webhook (“post to a channel when a webhook request is received”).

The address is the secret that lets anyone post to the channel: it is stored encrypted and never shown again once saved.
