I would like to say, thank you for your help first!

I am using [x.thunkable.com](http://x.thunkable.com) (not drag&drop version) to build my app.  
I need to use hash function.  
How to use or create it?  
I believe extension is not supported anymore.

Can you say a little more about what you’re trying to do?

Also, there’s no need to post in ALL CAPS. I edited your topic title.

You’ll need to explain more if you want help. I still don’t really understand, sorry.

Why do you need a hash? Is it for security? If you are getting a JSON response, you can just parse it in Thunkable. Still not sure about the need for the hash. Can you provide an example?

This is a security purpose. I am going to hash a JSON response and store it into blockchain so that I can check later if it is tampered or not.

Okay. Well I think you’ll need to use an API to do that. I don’t know of a way to create a hash within Thunkable unless you know what the algorithm is and how to program it.
