200 OK This is the standard response for successful HTTP requests. When using the api to query a table, the OEP will return this status if the table does indeed exist.
201 Created The OEP will return this e.g. when you have successfully created a table.
400 Bad Request The OEP cannot process the request, because of a malformed query, use of an unsupported syntax or some other faulty user input.
403 Forbidden The OEP understands the request, but the current user is not allowed to perform the action. This may be the case when you try to write to a table that is in a different schema than model_draft, you did not log in for a certain action, or you did not provide your key for a data upload.
404 Not Found The requested resource or page does not exist or is not available.
500 Internal Server Error Something unexpected happened and no more specific message is suitable. These should be rare, but if they do occur, a developer will receive a mail about it, so they can try to fix the issue.
