Unique ID for a flow instance

I'm going to write data into a sharepoint list and read it again later from the same list.

 

However I want to avoid the problem, that two instances of my flow could interfer by accessing the same list items. So my idea is, to write a unique ID into a column of  that list and filter for it when re-reading the data. So, where to get a unique ID?

 

In my opinion the best option was to use something connected to the flow instance. I know there's a ID for the flow, but is there an identifier for the instance as well? And if so, where do I get it?

 

Other option is to use a timestamp but in rare cases this timestamp won't be unique as well. Other ideas?

Hi,

 

To get a unique id, you can use one of the expression below:

 

unique id of flow:  workflow()?['name']

 

unique id of flow run: workflow()?['run']?['name']

 

bonus: 

flow name: workflow()?['tags']?['flowDisplayName']

Works like a charm! Is there an overview over all the properties of workflow()?
