Upsert
A database operation that inserts a new record if it doesn't exist, or updates it if it does. Critical in sync workflows rather than checking for existence first (two API calls), an upsert does it in one. Prevents duplicates and handles updates automatically.
Expert insight
An upsert (update if exists, insert if not) needs a reliable, unique key to match against, an upsert using a poorly chosen matching key (like a name, which isn't unique) will either create unwanted duplicates or overwrite the wrong record, the matching key choice matters as much as the upsert logic itself.
In a real workflow
A contact is updated if the email exists, or created if not, in one operation.
Common mistakes
- Upserting on keys that are not unique.
- Overwriting good data with empty values.
Complexity level
Requires some familiarity with automation concepts.
