# GET /chained_events/{entityId}

`GET /chained_events/{entityId}`

Get the chain of successive events also with forks but no super or sub events if they are not in the chain.

## Path parameters

- `entityId` integer, required

## Response `200`

Success

- ChainEventModel
  - `name` string, required
  - `id` integer, required
  - `system_class` string, required
  - `geometry` union, required
    - Polygon
      - `type` 'Polygon', required
      - `coordinates` LinearRing[], required
        - Position[] — An array of four or more positions where the first and last positions are equivalent (they represent closed loops). Used for defining polygon boundaries.
          - number[] — A single position represented as an array of numbers. The first two elements MUST be longitude and latitude (in that order). An optional third element represents altitude. More elements are discouraged. Example: [10.9787, 49.7606] or [10.9787, 49.7606, 150.5]
      - `title` string

      - `shapeType` 'area' | 'shape'
    - Point
      - `type` 'Point', required
      - `coordinates` number[], required — A single position represented as an array of numbers. The first two elements MUST be longitude and latitude (in that order). An optional third element represents altitude. More elements are discouraged. Example: [10.9787, 49.7606] or [10.9787, 49.7606, 150.5]
