Can i use Picasa API for wallpaper app in thunkable ? if yes! How ?
Hi and welcome to Thunkable,
you need to learn about the API first. You can find informations how to use here:
Then you might be able to use the API with the Web component if the API supports Web requests (get, post,…) You can find all Thunkable components and blocks explained in the Thunkable Docs
You can also search for Tutorials on how to work with APIs. One that might be helpful:
Good luck and happy THUNKing!
