Data Schemas

Below are descriptions and JSON examples for all data schemas recognized by the Eagle Eye Cloud VMS. Each event type can be associated with a number of these data schemas. These may be included when inserting events via the api/v3.0/events endpoint. You can find a list of the existing events and their associated data schemas in the Event Types guide.

curl --location 'https://api.cxxx.eagleeyenetworks.com/api/v3.0/events'  
--header 'Authorization: Bearer <token>'
--header 'Content-Type: application/json'
--data '\<event_json>'
