}Overview
The upsert endpoint intelligently creates a new company or updates an existing one based on configurable duplicate detection strategies. It automatically handles conflicts and prevents duplicate records using exact matching, fuzzy matching, or AI-powered similarity detection.Endpoint
PUT http://api.gu1.ai/entities/upsert
Authentication
Requires a valid API key in the Authorization header:Authorization: Bearer YOUR_API_KEY
Request Body
object
required
The company data (same structure as Create Company endpoint)
object
Configuration options for upsert behavior
enum
How to handle conflicts when an existing company is found:
source_wins- New data overwrites existing datatarget_wins- Keep existing data, ignore new datamanual_review- Flag for manual review without updatingsmart_merge(default) - Intelligently merge both datasets
enum
Strategy for detecting duplicate companies:
exact_match- Match by externalId and taxId (case-insensitive)fuzzy_match- Similarity matching on name and taxId (80% threshold)ai_similarity- AI-powered semantic similarity detectionhybrid(recommended) - Exact match with fuzzy fallback
boolean
default:"true"
Whether to automatically create relationships between entities
Response
boolean
Indicates if the operation succeeded
string
The action performed:
created or updatedobject
The final company state after upsert
object
The company state before update (null if newly created)
number
Confidence score (0-1) for the duplicate detection match
string
Explanation of why the company was created/updated
array
Array of field-level conflicts detected during merge (if any)

Best Practices
-
Choose the Right Strategy:
exact_matchfor clean, structured data with reliable IDsfuzzy_matchfor user-entered data with potential typoshybridfor most production scenarios
-
Handle Conflicts Gracefully:
- Use
smart_mergefor automatic resolution - Use
manual_reviewfor critical data - Check
conflictsarray in response for important changes
- Use
-
Monitor Confidence Scores:
- Scores below 0.7 may indicate weak matches
- Log low-confidence updates for review
Error Responses
400 Bad Request
{
"error": "Invalid tax ID format for country"
}
500 Internal Server Error
{
"error": "Failed to upsert entity"
}
Next Steps
- List Companies - Query upserted companies
- Update Company - Make targeted updates
- Get Company - Retrieve full company details
