# End notes

Some information has been omitted to keep this document brief and quick to understand, for example error handling has been omitted, the error responses are provided in the API reference.

A particular error status was also not mentioned: 403 Forbidden, the client may receive a 403 if the incorrect API key is used for ordering, or if the API Key was not configured to perform the specified action.

If a 403 is received and it is believed to have happened in error, then contact support with the action that was taken and the API Key that was used for the request, it should be resolved in a timely manner.
