Android Inline Installs is a Google Play-powered capability enabled by the InMobi SDK that allows users to install an advertised app directly within the ad experience, without redirecting to the Google Play Store.
This experience leverages the Google Play Install API to present app product details in a native, in-context interface, allowing users to complete the install flow without leaving the host app.
For DSPs and advertisers, this results in a more seamless user journey, reducing friction in the clickthrough flow and improving key metrics such as conversion rate, and overall campaign efficiency (IPM, CPA, CPI).
The integration follows a two-sided OpenRTB handshake:
Support Center
imp.ext.inlineinstallallowedseatbid.bid.ext.inlineinstallInMobi can also enable this feature on behalf of DSPs that do not support RTB based activation or install referrer based attribution. Please contact your Demand Partner Manager to discuss enablement.
InMobi sets inlineinstallallowed = 1 only when all of the following conditions are met:
Object: BidRequest.imp.ext
| Field | Type | Required | Description |
inlineinstallallowed |
integer | Yes | 1 = available, 0/ absent = not available |
"ext": {
"inlineinstallallowed": 1
}
Object: BidResponse.seatbid[].bid[].ext.inlineinstall
| Field | Type | Required | Description |
|---|---|---|---|
enabled |
boolean | Yes | 'true' to activate, false to opt out (default value is 'true'). |
referrer |
string | No* | Referrer string passed by the SDK to the Play Install API for attribution. * Strongly recommended. |
"ext": {
"inlineinstall": {
"enabled": true,
"referrer": "dsp1_760a59d6-1507-11f1-96c3-9565488fcc70"
}
}
bid.bundle (the advertised app's package name) is required when enabled=true.
The InMobi SDK calls the Google Play Install API directly on the device. The flow bypasses the Play Store redirect entirely, which means:
You must pass the referrer explicitly in the bid response for attribution.
Without a referrer:
We recommend passing the install referrer explicitly in the bid response for attribution. If the DSP does not use Install Referrer for third-party attributions, then this recommendation may not be relevant for you.
InMobi passes the referrer to the Google Play Install API exactly as received. It does not validate or modify the value.
The referrer field is optional at the protocol level. However, it is strongly recommended for any campaign where you need install attribution. Since the InMobi SDK calls the Play Install API directly (rather than redirecting through a Play Store URL), there is no redirect chain for the MMP to read a referrer from. The only way to pass a referrer in this flow is explicitly through this field.Without it:
If inlineinstallallowed is absent or set to 0 in the bid request, the device is not eligible for Inline Install. Setting enabled=true in the bid response will have no effect — the InMobi SDK will fall back to standard store redirect behaviour. DSPs should treat inlineinstallallowed = 1 as a prerequisite before activating Inline Install.
InMobi may enable automatic Inline Install opt-in for DSPs who have agreed to it. When auto opt-in is active, eligible impressions will be treated as opted-in by default, even without an explicit enabled=true in the bid response.
To override this and explicitly opt out of Inline Install for a specific bid, set enabled=false in the bid response extension.
Yes. When enabled=true, DSP must include a valid bid.bundle in the bid object. This is the Android package name of the app to be installed (e.g. com.advertiser.game). The SDK uses this to identify the app on the Play Store. Bids with enabled=true and a missing or invalid bundle will not be processed for Inline Install.
Yes, click trackers will be invoked as usual when the user clicks on the ad.
