## Prerequisites

*Performed by: Developer*

* See the [Compatibility Matrix](/reference/compatibility-matrix) for the minimum Android and iOS versions for this package.
* The GMA Unity plugin must be imported and AdMob app IDs set under **Assets → Google Mobile Ads → Settings**


## Install the SDK

*Performed by: Developer*

In Unity **Package Manager → Add package from git URL**:

```
https://github.com/tapmind-tech/TapMind-CA-Admob-Unity.git
```

TapMind's Unity package uses a **post-processing script** that automatically adds the native Android and iOS dependencies during the Unity build. Git tag-based pinning is not used - add the package from the repository URL above.

Import the GMA Unity plugin and set AdMob app IDs under **Assets → Google Mobile Ads → Settings**.

## Configure Google Ad Manager

*Performed by: Ad ops*

**Create the TapMind company:** Admin → Companies → New company → type Ad Network → name **TapMind** → Ad Network **Other Company** → toggle Mediation on → Save.

**Create/open a yield group:** Delivery → Yield groups → New yield group → name (from your account manager) → set ad format → inventory type **Mobile** → target your ad units.

**Add the yield partner:** Add yield partner → select TapMind → Integration type **Custom Event** → Status **Active** → platform **Android or iOS** →

### Android

```
Default CPM : provided by your account manager
Label       : provided by your account manager
Class Name  : com.tapmind.mediation.TapMindAdmobAdapter
Parameter   : {"placementName": "provided by your account manager"}
```

### iOS

```
Default CPM : provided by your account manager
Label       : provided by your account manager
Class Name  : TapMindMediationAdapterAdmob
Parameter   : {"placementName": "provided by your account manager"}
```

> The **placementName** value is case-sensitive and must exactly match the Placement Name configured in the TapMind Dashboard.

**Note:** Official Google documentation: [Create a yield group](https://support.google.com/admanager/answer/7390828)

## Verify integration

*Performed by: Developer*

After install and dashboard configuration:

1. Run your app in a **debug** build. TapMind's test mode is enabled automatically in debug builds and serves test ads at a high fill rate.
2. Request an ad through your mediation SDK as you normally would.
3. Confirm a TapMind ad fills. Check logs for the tag **`TapMindAdapter`**.
4. When verified, build in **release** mode for production - test mode is disabled automatically in release builds, and live ads serve.

**Note:** Test mode is automatic. It follows your build type: debug = test ads, release = live ads. There is no flag to enable or disable, and nothing to turn off before going live.

**Release build QA:** There is currently no documented release-safe test path to validate R8/ProGuard without serving live ads. Consumer ProGuard rules from the TapMind AAR are applied automatically when you integrate the published adapter packages.

## Troubleshooting

*Performed by: Developer*

Before diving into logs, confirm adapter class names and the LevelPlay network key against the [Class & Network Key Registry](/reference/class-network-key-registry), and `placementName` and eCPM/rate with your account manager.

See [Troubleshooting](/reference/troubleshooting) for common symptoms, mediation-specific fixes, release vs debug guidance, and escalation steps. Partner-specific verification steps are under **Verify integration** above.
