HTTP Response Codes and Errors
The Genesys Web Engagement Backend Server returns HTTP status codes and messages for every operation, in the requested format. Status codes match standard HTTP codes, but messages can differ and provide additional details included in the header of the response.
Successful Result
A successful response to a request is marked by HTTP Status Code 200 (OK). In that case, your application may get additional information in the header and the body of the response. Refer to the Response section of your operation's page to get the detailed list of returned information. The following table lists the standard HTTP codes used by Genesys Web Engagement Backend Server for a successful response.
| Code | Title | Description |
|---|---|---|
| 200 | OK | Success! |
| 204 | No Content | For "filtered collection read" requests only. The request was correct and successful but the server has no appropriate entities to return. |
Errors
For responses with HTTP status code 4xx or 5xx, the response body contains an application-specific description of the error instead of a representation of the requested resource. The following table lists the specific errors that operations can encounter. This list is not restrictive; additional error codes could be returned due to external web servers and layers involved:
| Code | Title | Description |
|---|---|---|
| 400 | Bad Request | General error which could be caused by:
|
| 401 | Not Authorized | Credentials are missing or incorrect, or the given user is not allowed to execute a given service (such as an administrative service method that changes the profile schema). See Basic Access Authentication. |
| 403<ref name="r400">Not available for now.</ref> | Forbidden | The operation is forbidden and the reason is specified in the error message. |
| 404 | Not Found | For "identified entity read" request only. The specified URI is invalid, or the requested resource (such as identity, visit, event, and so on) does not exist. |
| 500 | Internal Server Error | An unexpected error occurred in the Web Engagement Backend Server (for instance, a runtime exception). The error message suggests you forward logs to Genesys Customer Care. |
| 502 | Bad Gateway | Returned when one or more of the backend systems required to fulfill the response (the Cassandra database or the Genesys environment, for example) are either unavailable or returned an error. |
| 503 | Service Unavailable | Web Engagement Backend Server is unable to process the given request. Example situations include:
