Successful requests will return a HTTP 200 response and may or may not include a response body, depending on the request endpoint.

Whenever a problem occurs, Wyre will respond to the client using a 4xx or 5xx status code. In this case, the body of the response will be an exception object which describes the problem. All
4xx status codes indicate a problem with your request, while a 5xx status code indicates an internal problem with our systems.

All exceptions come equipped with an exception ID (the exceptionId field). If you require
support, please supply this exception identifier to assist our support team in locating your issue.

The following table describes the fields included in the returned JSON exception:

Field	Description
`exceptionId`	A unique identifier for this exception. This is very helpful when contacting support
`type`	The category of the exception. See below
`errorCode`	A more granular specification than `type`
`message`	A human-friendly description of the problem
`language`	Indicates the language of the exception message
`transient`	In rare cases, an exception may signal `true` here to indicate a transient problem. This means the request can be safely re-attempted

An example JSON representation of an AccessDeniedException:

{
    "language": "en",
    "exceptionId": "TLFN89",
    "errorCode": "accessDenied.invalidSession",
    "message": "Invalid Session",
    "type": "AccessDeniedException",
    "transient": false
}
