Just like subscribing to balance changes, this will trigger an event every time a new block is mined, and publish a state with the block number.

Setup

This action doesn't have any fields, just run it after the api was initialised.

Action - Unsubscribe from new Block event

After subscribing you can of course unsubscribe by running this action and receiving events about new blocks.

Event - New Block

This is the event that will be triggered every time a new block is mined.

State - Last Block Nr

In this state you will find the number of the latest block.

Demo

Find a demo on the page. See the workflow folder Subscribe blocks
