ExtensionData

Any custom data to collect about an event in addition to the other attributes provided for the event data.

Objects of this type can contain maximum 50 custom attributes. The data becomes available in Sitecore CDP and Sitecore Personalize.

Use a flat object structure. Nested objects will be automatically flattened, and keys will be renamed as necessary.

export type ExtensionData = NestedObject;

{ customKey: "customValue" }
