# In-App Bidding

## Overview

__In-App Bidding__ allows you to create a real-time competition between direct sales, Equativ SSP and third party ad networks just like header bidding does in a web environment.

## How does it work?

Like header bidding on the web, when an advertising opportunity occurs, your application may want to call third party partners to get a real-time CPM for that opportunity. These partners will return you an ad response and a CPM for the ad impression.

If you are using an advertising SDK that handles __In-App Bidding__ competition between several partners, you can call our **Equativ Display SDK** as a partner by using the `SASBiddingManager` object. Indeed, through the `SASBiddingManager`, the **Equativ Display SDK** will return -in case of success- an ad response along with its CPM that you can use in your __In-App Bidding__ competition.

## The `SASBiddingManager` class

The `SASBiddingManager` object works the same way on both _Android_ and _iOS_ platforms.

You need to pass 3 parameters when creating a `SASBiddingManager` instance:
- an ad placement
- an ad format
- a currency

When performing an ad call, in case of success, the `SASBiddingManager` will return a `SASBiddingAdResponse` object containing the ad response and the ad price (defined by its CPM and currency).
