Invalid Network Credentials in Admob mediation process

Question

Entering Facebook App id and Access token throwing Invalid network credentials. For mediation I followed this Integration link https://developers.google.com/admob/ios/mediation/facebook.

As one of the steps, I don't find any apps to select in the list. Attaching the screenshot as shown in integration steps.

I only doubt for Invalid network credentials by missing this step in my flow.

Answer 1

nowadays Admob asks for property id. from Facebook you only get a placement id. in that placement id use the text before underscore as property id in google Admob.

for example, if 123456789101112_13141516171819 is your placement id, 123456789101112 should be your property id
