Many API calls include app tokens as an added layer of security. You assign tokens to an application that match the tokens in API calls to that application. In rare cases, you may want to remove a token from an application.
Note: Be sure you want to remove the application token. When you do so, API calls citing the removed token will fail to work if tokens are required for that application.
To remove an application token:
In the list, locate the token that you want to remove, then click Remove.
The token is deleted, and API calls containing that application token no longer work.
