HTTP 204 No Content vs 429 Too Many Requests
HTTP 204 (No Content) is a 2xx Success response, while 429 (Too Many Requests) is a 4xx Client Error response. 204 indicates that the server successfully processed the request but is not returning any content. Common for DELETE operations and form submissions that don't need a response body. In contrast, 429 means that the user has sent too many requests in a given time (rate limiting). The response should include a Retry-After header.
