Create a Notion credential.\n2. Add it to the Notion nodes, selecting the appropriate database.\n3. In the \"Set\" node (\"Format items properly\"), specify a reference to the property you want to check for duplicates and assign it to the field \"property_to_check\". I recommend using the n8n property drag-and-drop feature.\n4. Enjoy!\n\n### ABOUT THE TRIGGERS\nThis workflow offers two possible triggers by default:\n- Run every time a page is added to the database.\n- Run every day.\n\n\nYou can enable, disable, or modify these triggers as you like."
