# Targeting attributes

When you create ASRouter messages such as contextual feature recommendations or onboarding cards, you may choose to include **targeting information** with those messages.

Targeting information must be captured in [an expression](./targeting-guide.md) that has access to the following attributes. You may combine and compare any of these attributes as needed.

Please note that some targeting attributes require stricter controls on the telemetry than can be collected, so when in doubt, ask for review.

## Detailed usage

### `addonsInfo`
Provides information about the add-ons the user has installed.

Note that the `name`, `userDisabled`, and `installDate` is only available if `isFullData` is `true` (this is usually not the case right at start-up).

**Due to an existing bug, `userDisabled` is not currently available**

#### Examples
* Has the user installed the unicorn addon?
```java
addonsInfo.addons["unicornaddon@mozilla.org"]
```

* Has the user installed and disabled the unicorn addon?
```java
addonsInfo.isFullData && addonsInfo.addons["unicornaddon@mozilla.org"].userDisabled
```

#### Definition
```ts
declare const addonsInfo: Promise<AddonsInfoResponse>;
interface AddonsInfoResponse {
  // Does this include extra information requiring I/O?
  isFullData: boolean;
  // addonId should be something like activity-stream@mozilla.org
  [addonId: string]: {
    // Version of the add-on
    version: string;
    // (string) e.g. "extension"
    type: AddonType;
    // Version of the add-on
    isSystem: boolean;
    // Is the add-on a webextension?
    isWebExtension: boolean;
    // The name of the add-on
    name: string;
    // Is the add-on disabled?
    // CURRENTLY UNAVAILABLE due to an outstanding bug
    userDisabled: boolean;
    // When was it installed? e.g. "2018-03-10T03:41:06.000Z"
    installDate: string;
  };
  // Has the user installed addons beyond the built in and system addons?
  hasInstalledAddons: boolean;
}
```
### `attributionData`

An object containing information on exactly how Firefox was downloaded

#### Examples
* Was the browser installed via the `"back_to_school"` campaign?

declare const attributionData: AttributionCode;
interface AttributionCode {
  // Descriptor for where the download started from
  campaign: string,
  // A source, like addons.mozilla.org, or google.com
  source: string,
  // The medium for the download, like if this was referral
  medium: string,
  // Additional content, like an addonID for instance
  content: string
}
```

    // e.g. google.com
    source: string;
    // category of the source, such as "organic" for a search engine
    // e.g. organic
    medium: string;
    // identifier of the particular campaign that led to the download of the product

Impressions are used for frequency capping so we only store them if the message has
`frequency` configured.
Impressions for badges might not work as expected: we add a badge for every opened
window so the number of impressions stored might be higher than expected. Additionally
not all badges have `frequency` cap so `messageImpressions` might not be defined.
Badge impressions should not be used for targeting.
