An incoming webhook is a secret URL that posts into one channel. It accepts the same JSON as Slack's incoming webhooks and the cards tools send to Microsoft Teams, so a monitoring tool, CI pipeline or form only needs the new URL. Block Kit blocks show as cards with headers, facts, images and link buttons.
For Engineering and ops teams with alerts, deploys and forms that already post somewhere.
An admin adds an incoming webhook in workspace settings, names it, picks the channel and copies the URL, shown once. Post to it with text, blocks, attachments, a username and an icon, as a JSON body or a form with a payload field, and Freesbe answers ok like Slack does. Messages show under the webhook's name or the username you send, and each attachment shows with its colour bar, text, fields and pictures, the way monitoring alerts are meant to look.
Blocks in Slack's Block Kit format show as a card: headers, sections with fields and a small picture beside them, context lines, dividers, images and buttons that open a link. The same URL also takes what tools send to Microsoft Teams, an Adaptive Card on its own or inside a message payload, or an older Office 365 connector card, and shows its text, facts, images and Open URL buttons. A tool set up for a Teams channel posts to Freesbe with a new URL.

The cards your tools post look the same in the mobile app: the header, the facts in two columns, the picture and the link buttons, so an on-call engineer sees the alert and opens the runbook from the lock screen's notification. Anyone can reply in the card's thread to say they're on it.
In the Admin Center, search your webhooks by name, address, channel or who added them. Each webhook's card has Deliveries, the log of recent deliveries kept for 14 days, Send test, and a menu to edit it, make a new URL, turn it off or delete it. A webhook acts for the admin who made it and turns off if that person is deactivated, until another admin turns it back on. Adding and deleting webhooks is recorded in the audit log.
