If you haven't linked your Facebook account, use the following guide.
Before you start
Make sure you use Appodeal SDK 2.10.3+/Appodeal Unity plugin 2.14.5+.
Make sure BidMachine is enabled in Mediation Settings.
Make sure you have a BidMachine Adapter in your project.
BidMachine Adapter is included in Appodeal SDK by default, make sure you haven't removed it from the project.
Step 1: Choose an ad unit for each ad type with the best performance to use it with Header Bidding.
Go to your Dashboard, create a report with filters App, Ad Network - Facebook, split by Line Items and Ad Type, add Ad Revenue measure.
You can use this template to generate a report. Select your App in it
Choose one ad unit for each ad type with the highest revenue. You will need to add them to Header Bidding later.
Step 2: Go to App Settings → Mediation Settings → Line Items, select the ad type and open the Facebook line items list.
Save the code for chosen Line Item and remove all the Facebook Line Items.
Step 3: Create a new In-App Header Bidding Line Item.
Click the Add Line Item button, enable In-App Header Bidding mode and fill in the Line Item’s label, default eCPM.
Use the same Line Item Code (placement ID) of the ad unit chosen in step 1 and saved in step 2.
Note: It is necessary to set up In-App Header Bidding mode, otherwise Facebook Audience ads won’t work.
Note: Code is a placement id. Code must have the following format:
If the first part of the placement ID does not match the app ID, Appodeal won’t receive your revenue data from Facebook Audience Network. To fix it, change the first part of the placement ID to the app ID. To reload revenue data, contact our support team.
