I have been scratching my head on this one since there seems be a simple solution.
First half of the task is pull all Lead Opportunity info from Lead Connector (Highlevel) into trelllo. I got this up and running.
The second half, asks me to upload trello comments to the same opportunity on Highlevel but the flow I made creates new Opportunity instead of updates the existing one. I think there is an Opportnity ID I can use to look up the existing opportunity and sync the updates to - just not sure how that all connects somehow. Appreciate any help,
