Device Identifiers
MoPub support for device identifiers in OpenRTB includes advertising identifiers (IFA), vendor identifiers (IFV) and frequency capping identifiers (user.id).
If the IFA is not available, MoPub provides DSPs with an alternative, limited-scope device identifier in order to provide basic non-targeting functionality to advertisers.
Examples of this include frequency capping, fraud detection and analytics. Below is a detailed list of supported identifiers and their scope.
Advertising Identifiers
MoPub supports the following user-resettable device identifiers via the BidRequest.device.ifa
field:
- iOS: ID for Advertisers (IDFA)
- Android: Google Advertising ID (GAID) and Amazon Advertising ID (AID)
Vendor Identifiers
MoPub supports the following vendor device identifier via the BidRequest.device.ext.ifv
field:
- iOS: ID for Vendors (IDFV) when IDFA is not available
- Android: No vendor ID equilvalent currently exists on Android
Frequency Capping Identifiers
MoPub supports the following vendor device identifiers via the BidRequest.user.id
field:
- iOS: IDFA (when available), else IDFV (when avaliable), else a per app MoPub-specific device identifier
- Android: GAID or AID (when available) else a per app MoPub-specific device identifier
Bid request
Here are the fields where DSPs can find these device identifiers.
Attribute | Description | Type | Example |
---|---|---|---|
BidRequest.device.ifa | Preferred device identifier to pass. For iOS, is all zeros unless permission to track has been granted. | string | "ifa": "5CD1D2BF-7958-4955-A964-95DBF9ABF780" |
BidRequest.device.ext.ifv | IDFV of device in that publisher. Only passed when IFA is unavailable or all zeros. | string | "ifv": "336F2BC0-245B-4242-8029-83762AB47B15" |
BidRequest.user.id | Equal to BidRequest.device.ifa if the IFA is non-zeroes. Else, the IFV if available. Else, a MoPub-specific device identifier for each user within each app. | string | "id": "9B9BF1EF-0646-467D-A09A-5478B7DFC130" |
