Does Certain integrate with Marketo?

✅ YES. Certain supports Eloqua through both Signal and EventStream, and our Eloqua integrations can use OAuth2 or Basic Authentication. For Signal, the Eloqua user must have permissions like Create Contacts, Add Contacts to a List, and External Activities. For EventStream, we connect native event automation directly inside the Eloqua canvas. Signal Integration with Eloqua Guide, Certain EventStream

If you want, I can also outline the exact setup path for your Eloqua account or integration goal.
