You will require the Publishing and Reporting roles to access the Authentication keys page. See Roles and permissions for more information.

Although Qubit supports both the JSON and P12 formats, we strongly recommend creating a JSON key file.

Select Settings from the side menu and then Auth keys in the top-right hand corner

Select New key and enter a name for the key

WARNING: The key cannot contain special characters.

Select Create and download JSON to download the key file. Make a note of the location where you downloaded the key to as you will need this to complete the upload

Now that you've created the key, you will need to configure it so that it can be used for batch uploads. To do this, follow steps 2 and 3 in Configuring An Existing Key For Programmatic File Transfer.
