Error codes
The below error code information is important in the context of our APIs.
Response body
The following response body is consistent across API methods and signifies that an error has occurred. In addition, it provides a way to ensure that the error response was generated by the API method being accessed (for example, when the resource id provided does not correspond to any known system entity) and not by the web server (for example, when the supplied URL is undefined).
| Parameter | Description |
|---|---|
| Status | HTTP status code returned by the API. See Response codes. |
| x-viva-eventId | Event identifier corresponding to the event. See Rejection reasons. |
| Response message | Reason phrase of status code, usually contains a description of x-viva-eventId. See Rejection reasons. |
Response codes
Viva Wallet uses conventional HTTP response codes to indicate the success or failure of an API request. In general, codes in the 200 range indicate success. 400 codes indicate a client-side error. 500 codes indicate an error with Viva Wallet’s servers.
| Status | Meaning | Message |
|---|---|---|
| 200 | OK | The request has succeeded. The meaning of the success depends on the HTTP method:
|
| 400 | Bad request | The server could not understand the request due to invalid syntax. |
| 401 | Unauthorized | Although the HTTP standard specifies "unauthorized", semantically this response means "unauthenticated". That is, the client must authenticate itself to get the requested response. |
| 403 | Forbidden | The client does not have access rights to the content; that is, it is unauthorized, so the server is refusing to give the requested resource. Unlike 401, the client's identity is known to the server. |
| 404 | Not found | The server can not find requested resource. In the browser, this means the URL is not recognized. In an API, this can also mean that the endpoint is valid but the resource itself does not exist. |
| 405 | Method not allowed | The request method is known by the server but has been disabled and cannot be used. |
| 406 | Not acceptable | You requested a format that isn't JSON. |
| 409 | Conflict | This response is sent when a request conflicts with the current state of the server. |
| 410 | Gone | This response is sent when the requested content has been permanently deleted from server, with no forwarding address. |
| 429 | Too many requests | The user has sent too many requests in a given amount of time ('rate limiting'). |
| 500, 502, 504 | Server error | Something went wrong at our end. Try again later. |
| 503 | Service unavailable | We're temporarily offline for maintenance. Try again later. |
The reason phrase will contain either an explanation of why the request could not be completed successfuly, or, an event ID corresponding to a sub-status.
Request format
There are several cases where a request parameter, either query param or body property, does map directly to a scalar value type or must be entered in a special format (ISO):
- Country codes must conform to the ISO 3166-1 alpha-2 standard.
- Dates must conform to the ISO 8601 standard and be entered in the following format 2018-11-12T14:31:58+00:00 in order for the time offset to be specified correctly.
- Currency fields must conform to ISO 4217 in numeric form.
