What is HTTP Status Code?
A three-digit number returned by a server indicating the result of an HTTP request.
Definition
HTTP status codes are standardized three-digit numbers in the response header that indicate the outcome of an HTTP request. They are grouped by category: 1xx (informational), 2xx (success), 3xx (redirection), 4xx (client error), and 5xx (server error). CronJobPro uses status codes to determine execution success: 2xx codes indicate success, while 4xx and 5xx codes trigger failure handling and potential retries.
Simple Analogy
Like a referee's hand signals in sports — a quick, standardized visual code that tells everyone the outcome of a play without needing a long explanation.
Why It Matters
Status codes are how CronJobPro determines whether your cron job succeeded. Returning 200 means success; returning 500 means failure and may trigger a retry. Understanding common status codes helps you configure proper success criteria and debug failures quickly by identifying the error type from the code alone.
How to Verify
In CronJobPro, every execution shows the HTTP status code returned. Common codes: 200 (OK), 201 (Created), 301 (Redirect), 400 (Bad Request), 401 (Unauthorized), 403 (Forbidden), 404 (Not Found), 500 (Server Error), 502 (Bad Gateway), 503 (Service Unavailable).
Common Mistakes
Returning 200 for failed operations (embedding error information only in the body). Not handling 3xx redirects — your cron service may not follow them by default. Treating all 4xx and 5xx codes the same when they require different remediation.
Best Practices
Return accurate status codes from your endpoint: 200 for success, 4xx for client errors, 5xx for server errors. Configure CronJobPro to treat only specific codes as success. Monitor the distribution of status codes over time to spot emerging issues.
