HTTP 424 Failed Dependency — Cascading Request Failure

Warning4xx client error

Overview

HTTP 424 Failed Dependency means the request failed because it depended on another request that also failed, common in batch or multi-step operations.

Key Details

  • Originally from WebDAV for multi-resource operations
  • Indicates a cascading failure — a prerequisite action failed first
  • Used when batch operations partially fail and dependent steps cannot proceed
  • The response should identify which dependency failed and why
  • Useful in microservice architectures where one service depends on another

Common Causes

  • A prerequisite API call in a multi-step transaction failed
  • WebDAV PROPPATCH where one property update failed causing others to fail
  • Microservice dependency returned an error, preventing current operation
  • Database transaction dependency failed, rolling back related operations

Steps

  1. 1Check the response body to identify which dependency failed
  2. 2Fix the root cause failure first, then retry the dependent request
  3. 3Implement proper error handling for cascading failures in your workflow
  4. 4Use transaction patterns or saga patterns for multi-step operations
  5. 5Add retry logic with the ability to resume from the failed step

Rarely, but some APIs use it for batch operations where one failed step prevents others from executing.
