Limitations

SaaS customers cannot use the generic table (table=generic) when executing multiple queries.
SaaS customers are allowed 600 requests every hour. This is enough to make just over ten requests per minute, per hour, which should meet the needs of most applications. Rate limiting applies only to authenticated API requests. Rate limiting does NOT apply for on-premise customers.
Notification that a client has exceeded the rate limit will be sent via HTTP status code of 403. The X-Error-Message header will describe the error. In order for you not to exceed the limits, we recommend that your application that uses the Celoxis API cache items that change infrequently e.g. time codes, expense codes and users. We also recommend that you submit items in bulk while updating through the API.
