milestone.reached

HMAC-SHA256 signed webhook event

The event hit a photo-count threshold (100, 500, 1000, 5000, 10000).

METHOD WEBHOOK EVENT
EVENT TYPE milestone.reached
AUTH HMAC-SHA256 signed

Fires once per threshold crossing. Great for live announcer prompts ("we just hit 500 photos!") or for triggering a sponsor shoutout on the wall. The latestPhoto reference points to the upload that pushed the count across the line.

AUTH NOTE

Outbound webhook delivery. Verify the `Fotowall-Signature` header against your event's webhook secret before trusting the body.
