# 1. Abonements: iegūt notikumus

Sekot abonementiem kad `IEVIETOT`/`MODIFICĒT`/`NOŅEMT` darbības notiek ar "Saime", "Lauks", "LaukaSatelītaAttēls", "RastrAnalīzesKarte", "VektoruAnalīzesKarte", citām vienībām.

Abonementu mehānisms balstās uz MQTT un WebSocket. Mūsu ieteikums ir sākt integrāciju, izlasot [AWS AppSync abonementa rakstu](https://docs.aws.amazon.com/appsync/latest/devguide/real-time-websocket-client.html). 

{% hint style="info" %}
Abonementa notikumi tiek nosūtīti tiklīdz notikums ir noticis GeoPard aizmugures sistēmā.
{% endhint %}

{% hint style="info" %}
Katrā abonementa notikumā ir unikāla identifikācija, ko sauc par `uuid`, kas ir noderīga apstrādāto un izlaisto notikumu filtrēšanai, kas pieprasīti no [82. Vaicājums: Atjaunot abonementa notikumus](/geopard-tutorials/lva/api-dokumentacija/geopard-api-pieprasijumu-parskats/82.-mutacija-atjaunot-abonesanas-notikumus.md).
{% endhint %}

{% code lineNumbers="true" %}

```graphql
subscription FollowPlatformEvent {
  followPlatformEvent(userUuid: "<placeholder_of_user_uuid>") {
    uuid
    userUuid
    darbība
    nodePath {
      entītija
      uuid
    }
  }
}
