HTTP status code summary (not limited to):
HIPS 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.), and codes in the 5xx range indicate an error with HIPS’s servers (these are rare).
Not all errors map cleanly onto HTTP response codes, however. When a request is valid but does not complete successfully (e.g., a card is declined), we return a 402 error code. To understand why a card is declined, refer to the list of codes in the documentation.
HTTP Code | Successful | Meaning |
|---|---|---|
200 | Yes | Your request was successful |
201 | Yes | Created - Your request was created |
202 | Yes | Accepted - Your request was accepted |
400 | No | Bad Request – Your request has invalid data. Check your parameters. |
401 | No | Unauthorized – Your API key is wrong, see Authentication |
402 | No | Payment Required - Card declined or no payments are made to an order |
403 | No | Forbidden – The requested data is restricted for your api key. |
404 | No | Not Found – The requested data is not found. |
406 | No | Not Acceptable – You requested a format that isn’t json |
429 | No | Too Many Requests – Your code is pounding our servers, to protect us from evil loops we have a request limit. Should you discover that you need to raise your limit, please contact support. |
5XX | No | Something went wrong on HIPS’s end. (These are rare.) |
7XX | ¯\ (ツ)/¯ | Sometimes, when you do something really unexpectedly silly, you might end up with a 7XX error. In that case we refer to 7XX-rfc :) |

api_connection_error | Failure to connect to HIPS’s API. |
api_error | API errors cover any other type of problem (e.g., a temporary problem with HIPS’s servers) and are extremely uncommon. |
