- Name your ad unit that exactly matches the name in your SDK code
- Select which app this ad unit belongs to (if not already selected)
- Choose an ad format
- Configure format-specific settings
- Click Save

Ad format settings
1. Banner, MREC:

- Reward amount - the number of items the user receives after watching the ad. For example, 10 coins or 1 extra life.
- Reward currency - the name of the reward. For example, coins, gems, or extra lives.
- Reward callback URL - a server-to-server callback URL that CloudX calls when a user completes a rewarded ad. Use this to verify rewards on your backend before granting them to the user.
After creating an ad unit
Once your ad unit is created:- Reference it in your SDK code using the exact ad unit name
- Create line items to define which demand sources serve ads and at what price
- Configure network mappings to connect your ad unit to demand partners
