Hi! I wanted help creating a nutrition app. I want my app to use an ocr scanner but instead of giving a decription i want the ocr scanner to read the image and let the user know if it is healthy or not.

I can help you get a single property and then you can look over the documentation, tutorial videos, etc. to learn about the rest. Be aware that a property with square brackets [2] indicates a JSON array which is handled by list blocks in Thunkable. And I mentioned this before but JSON/API data is d…

Thank you! For the nutrition score would I have to “initialize each app variable” for the nutritional information and then add it on the “get property of object” block?

This is the url I used: https://world.ope…

I’m glad it was helpful. The “nutriscore_grade” property is inside of the “product” property that’s inside of the object. So that’s it… just two of the “get property of object” blocks are needed for that value. There are websites that will help you find the “path” to a JSON property. I don’t tend t…

Okay! Thank you so much! I fixed that but when I try to test it, there is just a blank white screen that shows up. These are my blocks: [image]
