Unable to Extract Marketing List Members in Flow

Posted on by 241

Hi All,

I'm building a Flow that needs to extract contacts from an existing Marketing List in Dynamics, I'm going wrong somewhere and getting very stuck!

Table name: Marketing List Members

Row ID: Marketing List ID

I get the following error:

The 'Retrieve' method does not support entities of type 'listmember'. MessageProcessorCache returned MessageProcessor.Empty. 

I'm assuming that because it's multiple contacts within the members list that I'm getting this but I can't get my head around how I would output the list and then use them within the Flow. Any help or guidance would be hugely appreciated!

    Hi Sam,

    In the future for Flow/D365 questions, you can also try asking in the Power Automate integration forum:

    I answered my own question; I did a List Items with a Fetch Query based on the Contacts and added in Dynamic values for the Marketing List ID associated with the contacts.
