Just Wallet 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 etc.). Codes in the 5xx range indicate an error with our servers (these are rare).

Error 🚦 What
400 - Bad Request The request was unacceptable, often due to missing a required parameter.
401 - Unauthorized No valid API key provided.
402 - Request Failed The parameters were valid but the request failed.
403 - Forbidden The API key doesn't have permissions to perform the request.
404 - Not Found The requested resource doesn't exist.
409 - Conflict The request conflicts with another request (perhaps due to using the same idempotent key).
429 - Too Many Requests Too many requests hit the API too quickly. We recommend an exponential backoff of your requests.
500, 502, 503, 504 - Server Errors Something went wrong on Just Wallet's end. (These are rare.)
200 - OK Everything worked as expected 😊

Errors are returned when one or more validation rules fail or unauthorized access to API. Examples include insufficient fund during a call will result in a validation error. Here's a sample below:

                                "status": "failed",
                                "message": "Insufficient funds, please add funds to your account",
                                "data": "null"
