# Default Parameters

The Mapp Intelligence iOS SDK automatically attaches a set of default parameters to every tracking request. You do not need to set these manually — they are collected and sent by the SDK on your behalf.

## What the SDK attaches automatically

| Category | Examples |
| --- | --- |
| App identity | App name, app version, app build, bundle identifier |
| Device | Device model, OS name and version, screen size, language |
| SDK identity | SDK name and version (see [Retrieve Active Global Configuration](/v1/docs/mapp-intelligence-ios-sdk-v5-retrieve-active-global-configuration)) |
| Session | Session start (`fns`), one-time per user (`one`), everID (`eid`) — unless [Anonymous Tracking](/v1/docs/mapp-intelligence-ios-sdk-v5-anonymous-tracking) is active |
| Time | Server-side timestamp; client timestamp when enabled in your account |

## Override or extend default parameters

You can extend each tracking request with your own parameters by populating the relevant `MI…Parameters` object on the event before passing it to a `track…` method. For example:

- `MIPageParameters` for page-level data — see [Pages](/v1/docs/mapp-intelligence-ios-sdk-v5-pages).
- `MIEventParameters` for action-level data — see [Events](/v1/docs/mapp-intelligence-ios-sdk-v5-events).
- `MISessionParameters` for session-level data — see [Sessions](/v1/docs/mapp-intelligence-ios-sdk-v5-sessions).
- `MIUserCategories` for user-level data — see [Users](/v1/docs/mapp-intelligence-ios-sdk-v5-users).
- `MIEcommerceParameters` + `MIProduct` for commerce data — see [Products and Orders](/v1/docs/mapp-intelligence-ios-sdk-v5-products-and-orders).
- `MICampaignParameters` for campaign data — see [Campaigns](/v1/docs/mapp-intelligence-ios-sdk-v5-campaigns).

## Configure how default parameters are sent

- **App version on every request:** set `sendAppVersionInEveryRequest = true`. By default, the app version is included only in the first request of each session. See [Configure Global Tracking](/v1/docs/mapp-intelligence-ios-sdk-v5-configure-global-tracking).
- **Anonymous tracking:** when enabled, the SDK suppresses the everID and any parameters you list in `enableAnonymousTracking([...])`. See [Anonymous Tracking](/v1/docs/mapp-intelligence-ios-sdk-v5-anonymous-tracking).
