# Mapp Connect: Partial Updates for User Attributes in the Connect API

**16 January 2025**: We’re excited to announce a new improvement to the Connect API - partial updates for Custom User Attributes. With this feature, updating user attributes becomes more robust and flexible.

## Key Benefits

- **Error Resilience**: Isolated errors no longer disrupt the entire update process.
- **Improved Efficiency**: Ensures valid rows are processed without unnecessary retries.
- **Simplified Debugging**: Focus on fixing specific issues without reprocessing the entire data.

## How does it work?

When submitting a request to update custom user attributes, any errors encountered in a specific row will now only skip that row instead of dismissing the entire import. This ensures smoother operations and reduces the risk of losing valid updates.

The **Partial Update** feature is **deactivated by default**. To activate it, simply include the `partialUpdate` parameter set to `"true"` in the JSON body of your request.

Here’s an example of how to implement this feature:

```json
{
    "email": "jane.smith@example.com",
    "updateonly": "false",
    "firstName:CORE": "Jane",
    "lastName:CORE": "Smith",
    "myCustomAttribute:CUSTOM": "Preferred Language: English",
    "myMemberAttribute:MEMBER": "Loyalty Tier: Gold",
    "myLinkedRdAttribute:RD": "Region: North America",
    "myAddonAttribute:ADDON": "Newsletter Subscription: Yes",
    "partialUpdate": "true" // Enable partial updates
}
```

## Availability

This update has already been released.
