Funnel connects to Xandr with a login and password, but only if API access is enabled for that Xandr user. Most Xandr users don't have it by default.
Before you connect
Contact your Xandr account manager and ask them to enable API access for the user you'll connect with.
Wait for Xandr to confirm it's enabled.
Connect the data source
In Funnel, go to Data sources and add Xandr.
Enter the login and password of the API-enabled user.
Choose a report type, for example Advertiser analytics, Network analytics or Video analytics.
Choose the report currency: USD (default) or the advertiser's currency.
Finish the connection.
Common problems
The login is rejected even though it works in the Xandr UI: the user doesn't have API access yet. Ask your Xandr account manager to enable it.
Small differences in monetary metrics: these can happen when you choose advertiser currency, because of rounding before currency conversion.
