HTTP 400 Bad Request
HTTP 400 responses include an “ApiException" element in the response that contains a useful summary of the reason for the
error.
HTTP 401 Unauthorized
A customer may disconnect your application from within Xero at anytime so at the very least you should implement functionality
to handle a 401 error and allow a customer to easily reauthorize your application.
A description of the reason for the error is returned in response using the following format.
oauth_problem=xxxxxxxxxxxxxxxx&oauth_problem_advice=xxxxxxxxxxxxxxxxxx

HTTP 503 Rate Limit Exceeded
An application can make up to 5000 API calls against a particular Xero organisation in a rolling 24 hour period and 60 calls
against a particular Xero organisation in a rolling 60 second period. The following will be returned in the body if you exceed
a rate limit.
oauth_problem=rate%20limit%20exceeded&oauth_problem_advice=please%20wait%20before%20retrying%20the%20xero%20api

HTTP 503 Not Available
From time to time we might require a short outage to carry out maintenance or upgrades. In most cases the Xero API will respond
with a HTTP 503 when it is not available, and provide one of the following response bodies:
The Xero API is currently offline for maintenance
The Xero API is temporarily unavailable
HTTP 503 Organisation Offline
A specific organisation may not be available though the Xero APIs themselves are online. In this instance, the below response
will be returned. Typically this situation may occur for several minutes. A retry interval of 5mins or so is recommended.
The Organisation is offline
