Before integrating any TapMind SDK, make sure you have:

- A mediation account with the partner you're integrating (AdMob, GAM, AppLovin MAX, or Unity LevelPlay).
- An ad unit already created in that platform — TapMind targets your existing ad units.
- The Google Mobile Ads (GMA) SDK integrated in your app (TapMind's adapters run on top of it).
- Your TapMind values, provided by your account manager (see the split below).

## Two kinds of values — know which is which

| You set these | Your account manager provides these |
|---------------|-------------------------------------|
| Your app ID, your ad unit | placementName |
| Your eCPM/waterfall position | Adapter class name (or LevelPlay network key) |
| | Recommended eCPM / rate |

All TapMind-provided values live in one place — the [Class & Network Key Registry](/reference/class-network-key-registry). Use it as your single source of truth.

**Minimum OS:** see the [Compatibility Matrix](/reference/compatibility-matrix) for the confirmed minimum Android and iOS versions per package. (Values pending dev confirmation — «MIN-ANDROID» / «MIN-IOS».)
