The Application Key is used to authenticate requests. You may have one or more Application Keys for segmenting and tracking purposes.
To add an App Key, please log in to the FlightStats Developer Center:
At the top of the page, click this:
Under the list of App IDs (yours may be called Default) click:
Under Application Keys, click:
Create new key
The option to delete an appKey is only displayed if you have two or more appKeys. So you will need to create a new appKey before you delete the old one.
Note: Please do not confuse your Application Key(s) with your Application ID. Your Application ID is used as your account number and cannot be deleted for accounting reasons. To request new Application IDs, please email firstname.lastname@example.org and we'll assist.
