To connect Supermetrics to Outbrain Amplify, you will first need to obtain API access from Outbrain. You will not be able to use the connector until this step is done.
You can do this by contacting your account manager at Outbrain to whitelist the API access for your account. Or you can fill out this form requesting API access:
https://lp.outbrain.com/partner-api-form/
Once Outbrain has approved your API access, you can then log into the Supermetrics connector with the approved username and password.
