To start, let’s say your videos represent cars, so in your custom user data you want to keep track of a car’s make, year and models that each video will represent. To do this we will need to define a JSON array for each video. We will call our array, “cars”. We will show how to do this two ways either using the Create API or after a video object has been created using the Update API.
Now that we have shown how to add custom userdata, let’s say you want to make modifications. In the examples below we show you how to change the year and also add another model to cars userdata.
