API token is an important security measure as it authenticates you while accessing TestCollab API or use TestCollab's bi-directional app for JIRA.
Here are the steps to get a new API token generated:
Click on the profile picture or your initials shown on top right corner of the page
Select "My Profile Settings"
Switch to
API token
tab
Provide a label that matches the purpose of generating the API token, it will help in future. A token can however be used for more than one purposes.
Once you hit Create
the generated API token will be shown. Please note that this should be copied and stored at a safe location so that you can use it in future if needed.
You can have more than one API tokens generated for you for different purposes and they can have different life spans, as you do have option to revoke a token if you feel that it is no more required or if you doubt that its security has been compromised.
