If you are using Node Red and wish to use Polkadot or any Substrate chain from the tool you can use the Node Red substrate extension.

Check it out here:

>
> Provides a way to interact with a polkadot based chain through the JS client library.

This extension is being used by quite a few users already including the backend of polkawatch ([https://polkawatch.app/](https://polkawatch.app/))
