neoCatalog's API token can be used to interact with other applications. Note that when you generate a new token, the value will only be displayed once, so be sure to write it down.
In user management, from the user selection go to the tab API Key. In the field of token name, give a name for the token and click on Generate token.
You will get the token displaced. Copy the token and paste it where you need it. The token has unlimited validation. Below you will see all tokens listed that you can remove.
