207 Multi-Status

207 Multi-Status is defined by WebDAV (RFC 4918) and is used when a single HTTP request triggers operations on multiple resources. Each sub-operation can have its own status code. The response body is an XML document containing individual results.

Increasingly used in REST batch APIs to return mixed success/error results for bulk operations.

• WebDAV batch operations (PROPFIND, COPY, MOVE on multiple resources)
• REST batch endpoints processing arrays of items with mixed results
• File management APIs handling partial uploads or bulk deletes

• Parse each sub-response individually — do not treat the 207 itself as full success
• Check each item's status code in the response body
• Log failures per resource, not per request
• Document the response structure clearly in API docs
