Why does my Salesforce REST API upsert create duplicates instead of updating?
The External ID used for upsert is missing or not unique. Problem Explanation Upsert relies on External IDs to decide whether to insert or update a record. If Salesforce can’t match one record exactly, it inserts a new one. Root Cause(s) 1. External ID field not marked correctly 2. Null external IDRead more
The External ID used for upsert is missing or not unique.
Problem Explanation

3. Duplicate external ID values
Step-by-Step Solution
1. Mark field as External ID + Unique
2. Validate payload includes external ID
3. Clean existing duplicate records
Edge Cases & Variations
1. Case sensitivity matters for text external IDs
2. Bulk API handles failures differently
Common Mistakes to Avoid
1. Using Name field as External ID
2. Skipping uniqueness constraint
