Integrate third‑party app

I need to connect our meeting scheduler app to the CRM so new meetings log to contact records and create associated tasks. Authorize the integration with the third‑party app account, map the meeting fields to contact and activity, set it to create follow-up tasks for the rep who owns the contact, and test with three sample meetings this afternoon.

Before I enable this integration, make review easier for the team: show which meeting fields will overwrite contact data, surface any permission scopes that allow exporting contacts, list failure modes (missed mappings, duplicate contacts), and highlight what to watch on the first day after go‑live so support can react quickly.

I just completed the authorization for the calendar integration but I’m stuck on mapping where meeting notes should go. The app offers two activity fields and one could overwrite our contact notes. I don’t know which choice preserves historical notes and still shows the meeting on contact timelines. Which mapping is least destructive for our existing notes and what test should I run next to confirm?

Every few integrations we turn on, duplicates appear and reconciliation eats days. Where is the pattern breaking down — missing canonical fields, loose match rules, or post-import workflows — and what one change to our integration checklist will prevent duplicates without blocking valid updates?
