HTTP 424 Failed Dependency

4xx Client Error

4xx Client Error RFC 4918, Section 11.4

What is HTTP 424 Failed Dependency?

The 424 (Failed Dependency) status code indicates that the method could not be performed on the resource because the requested action depended on another action that failed. This is used in WebDAV batch operations where one sub-request depends on another.

Common Use Cases

Failed WebDAV batch operations
Transactional operation failures

Usage Example

When processing a WebDAV batch COPY where moving a file depends on first creating a directory, if the directory creation fails, any dependent file copy operations return 424 Failed Dependency. The response should reference the failed dependency.
