The first thing to check is whether you are in Sandbox or Production mode in the console. Click on the Developer tab on the left side of the console. At the top of the page, you can see if your console is running in Sandbox or Production mode and toggle between the two.
Finally, check to make sure you're using the correct API keys (available in the Developer's tab as well). API keys funnel the events you send into the accounts they belong to. In the example below, the console is in Sandbox mode so the Sandbox API keys are shown.
To learn the differences between your Sandbox and Production accounts, see this help article.
