HTTP 201 Created vs 429 Too Many Requests
HTTP 201 (Created) is a 2xx Success response, while 429 (Too Many Requests) is a 4xx Client Error response. 201 indicates that the request succeeded and a new resource was created. Typically returned after POST or PUT requests that create a new entity. 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.
