It all comes down to the final destination of your product information - human vs. Machine... So, what’s the difference between sharing information with people or machines?
Studies show people tend to digest information visually, but that also appears as realistic and tangible as possible, and for this reason and so to distribute content to humans we use PDF or E-catalogs.
Computers on the other hand have no feelings, they feed themselves with whatever information arrives, the only rule is the content/info (letters, numbers, …) needs to be flawless. And so when it comes working with machines, we would use the Channels and API features of the PIM.
Channels and Catalogs require product lists to distribute the desired and correct information with the end users. Both will be discussed in more detail in the next few emails, but if you can't wait then head to our help centre, where you can find detailed guides on to set all these up, as well as API documentation.
