What I meant was that you should set a Text Input’s text to the green [response] block and then copy the text it generates and paste it here. With a screenshot, I’d have to type in all of that JSON just to play around with it.
It’s also really helpful if you format it using the Preformatted text button in the forums toolbar. That way, smart quotes don’t invalidate the JSON.
You’re correct about JSON brackets [ ] signifying an array/list. By the way, I have a JSON parsing tutorial here: API JSON Tutorial (Video)
I’m not sure using an Alert’s title is the best idea for debugging. I believe it has a pretty limited string length. Labels (or Text Inputs if you need to copy & paste) are generally better.
