The overview in ”API & Forms” gives you the opportunity to review all your subscription forms and API Keys.
API Keys presents all your current keys to your API, how many subscribers you’ve collected since the key was created and a name and description of the API Key. Note that the API Keys are only shown if you’ve created them in the old tool. Hence, API Keys are now only used for legacy reasons and can’t be created in the new tool. Instead we recommend you to create API Tokens instead if you’d like to connect/use our API.
