Working with JSON

- [Narrator] FineMaker custom apps…are increasingly becoming part of an ecosystem…where all information is distributed,…and not just necessarily in one place.…REST APIs are a way for FileMaker custom apps…to communicate with third party data sources.…For example, I've created a FileMaker custom app…that acts as an inventory for books,…but instead of having to manually enter new book records,…I've created a system that allows us to scan ISBN codes,…which will then communicate with an API…that will bring that data in in the form of JSON.…

So, before we look at how we can parse out…the returning JSON data,…let's take a look at how this custom app works.…So, for example here, I'm going to scroll down to the middle…where I've go this button, which looks like a bar code…and then I'm going to use FileMaker's bar code scanning…to simply point it at the ISBN code…and as you see, it has scanned the bar code,…gone out to the API and pulled all of this data back,…and all FileMaker had to do was scan the returning JSON…and put it into the appropriate FileMaker fields.…
