Webhook
An HTTP notification sent automatically from one system to another when an event happens.
A webhook is an automatic HTTP request that software sends to a pre-set address when a certain event happens. You do not keep asking "is there anything new?"; the news comes to you when the event occurs. Tools such as Slack, Discord and n8n can receive these notifications and post them to a channel or trigger another task.
In digital signage, the most common use is fault alerts. When a screen in a remote branch goes down, a message lands in the team's channel shortly afterwards, instead of someone noticing it and phoning in.
Webhooks in MIA
When a screen goes offline, MIA sends an alert by webhook to tools such as Slack, Discord or n8n, and also to Telegram. When the screen reconnects, a "back online" message follows. Automating content updates from external systems through webhooks and a REST API can be built for your installation. More on the product page.
