Assets
UUID stands for Universal Unique Identifier. It is a unique alphanumeric string that is generated and assigned to each asset by the BLOX system. The UUID of an editorial asset can be found by going to the live or preview version of the asset and at the end pf the URL look for .html. The alphanumeric string right before it is the UUID. It will start with the asset type, such as article, image, YouTube etc.:
Ex: article_6e2509ac-a4b9-11e8-8249-4fa7125d80ab.html
This is the asset type, followed by an underscore (_) the UUID and then .html.
This can be done for all asset types.
Authors/Photographers
To find the UUID of the author there are a couple ways to find it:
If you are using Authors/Photographer in your assets you can go to an asset on the front end, click on their name or avatar. This will take you to their profile page. At the bottom of this page click View all.
In the URL of this page look for a= and an alphanumeric string. This is the author's UUID.
Ex: ?a=177da740-a4d1-11e8-8a54-ebcea8b7502a
