Class of the Alert. Contains machine-friendly

"code" as well as human-readable "label" fields.

| | title | String! | Summary describing the Alert contents | | text | String! | Full text of the Alert | | source | String | Represents news source URL for Alerts from the "news" dataset | | value | Float | Stores the value of the dataset at the point when Alert was created | | variable | String! | Describes the variable from the dataset which was used to create the Alert | | polarity | Int! |

| | company | [AlertCompany](/alerts-api/alerts-api-reference/alert-object.md#alertcompany) |

Holds additional data about the Company, Alert belongs to.

May be "null" in case Alert is related to multiple companies at the same time, when none of them is specifically an Alert target.

For example, a change of the aluminum price may affect many dependent manufacturers, but being a result of overall market movement, rather than an Alert for a specific company.

| | relatedCompanies | \[[AlertCompany](#alertcompany)!] |

Contains all the companies related to the parent Alert.

For example, a change of the steel price may affect multiple manufacturers.


When filtering by where.company.id, this list will still contain a full set of companies related to the Alert, not just those with matching IDs (but at least one of the Companies will have a desired ID)

| | payload | JSON! |

Holds additional metadata related to the specific Alert.

Please, note that the metadata structure varies depending on the Alert's dataset, variable and class.

You may find examples of payload Object here.
