What Is HTTP 204 No Content?
HTTP 204 No Content explained, and what it means when you see it in CI/CD and deployments.
HTTP 204 means the request succeeded but there is no content to return.
What it means
A 204 is common for DELETE requests and updates that do not need to return data. The response has headers but an empty body.
When you see it in CI/CD
CI tests assert 204 for delete endpoints. A common bug is code expecting a JSON body on a 204, which then fails to parse.
Key takeaways
- 204 means success with no body.
- Common for DELETE and PUT.
- Do not parse a body on 204.
