Webhooks
Both Teams Manager and External User Manager can push information to external apps and automations when a specific action occurs inside the app — for example when a space or guest request is created. The receiving platform can be Power Automate / Microsoft Flow, an Azure Function, or a plain HTTP endpoint.

Where to configure them
In both products webhooks live under Settings → Expert mode → Connected apps → Webhooks.
A webhook is defined by a name, a description, an optional secret, a trigger event, and the target URL of the receiving platform.
Webhook secret
The webhook secret lets the receiver verify that a request genuinely originated from the product. Any sufficiently random value works — the Teams Manager guide suggests generating a UUID.
Payload schemas differ per trigger and are shown in the product UI when you select a trigger. They are not reproduced here — see the product guides above for the current fields.
