Fill in the API key which can be found within your HubSpot account.
In your HubSpot account, click the settings icon in the main navigation bar.
In the left sidebar menu, navigate to Integrations > API key.
If a key has never been generated for your account, click Generate API key.
If you've already generated an API key, click Show to display your key.
