Packet uses conventional HTTP response codes to indicate the success or failure of an API request. In general: Codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, a charge failed, etc.). Codes in the 5xx range indicate an error with Packet's servers (these are rare).
HTTP status code summary
|200 - OK||Everything worked as expected.|
|422 - Bad Request||The request was unacceptable, often due to missing a required parameter.|
|401 - Unauthorized||No valid API key provided.|
|404 - Not Found||The requested resource doesn't exist.|
|500, 502, 503, 504 - Server Errors||Something went wrong on Packet's end. (These are rare.)|
