When viewing a Trello card, click on the Pipedrive Power-Up, start typing the contact’s name and click on the appropriate search result. The full contact item is attached to the Trello card. You can add people inside your organization and clients this way.
Set a rule in Trello that automatically creates a card, triggered by an event of your choice in Pipedrive. Set it up so that the moment a deal is marked as won, a Trello card with contact details, deal history, and organization information appears in a Trello board of your choice.
