The API token that you are using may have expired and you will need to generate a new one.
Click the User Avatar at the top-right and go to Settings.
On the Profile page, click Tokens. If you cannot access Tokens or don't see it, contact your Cognism account admin.
To generate a new API token, click + Create New.
Once the new API token is created, click the Clipboard icon to copy the token to be pasted where needed.
