Many thanks really … just last info: if I have more “row” and I have put them into a listview … which list block I have to do in place of this? Andrea ---

It is necessary to use “in list get” with the desired index, if the required field is in the array of objects. The array is what is between the parentheses [and]. ---

I am also having trouble with this. Here is the code: ![cat%20api%20code](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/f/0/f0e39d9d8505862cf0f7ff278cdd1e1d82b203de.png) #1 returns blank or “undefined” #2 blank or “undefined” #3 is [{"breed’:||,“catagories”:||,“id”;“egs”,“url”:“[https://24.media.tumblr.com/tumblr\_m4ikzs7XtT1r6jd7fo1\_500.jpg](https://24.media.tumblr.com/tumblr_m4ikzs7XtT1r6jd7fo1_500.jpg)”}] [https://24.media.tumblr.com/tumblr\_m4ikzs7XtT1r6jd7fo1\_500.jpg](https://24.media.tumblr.com/tumblr_m4ikzs7XtT1r6jd7fo1_500.jpg) is a valid link of a cat picture. The API send a different link every time is is called. I want to strip out the link and display it in the webviewer, using the property url, which I think should happen at #2, but it doesn’t work. Where am I going wrong? TIA ---

In your browser enter [https://api.thecatapi.com/v1/images/search](https://api.thecatapi.com/v1/images/search) and show me the answer. If the answer is no information, then you will not be able to. ---

The question is - why won’t my Thunkable code extract the property ‘url’ from that? ---

Because you incorrectly address this field. You are trying to get a field from an object, and the answer is not an object, but an array of one object. First get the object from the array at index = 1, and only then refer to its url property ---

I understood the problem. This is not a valid JSON format. Therefore it does not work. You must manually process this data. Now I’m busy, but after 3 hours I can make an algorithm, if that suits you.
