Errors handling


This property specifies the value of the status code returned by the server. Status values are defined in the HTTP specification and can be used either to identify an error or to confirm a successful operation.

When a request is successful, the API returns a HTTP Status Code (2xx).

Basic Error Codes

In case of any problems, will the API return the following HTTP status codes in the response header:

HTTP Status Code Description
401 Unauthorized. Wrong or missing credentials.
400 Bad format. Incorrect parameter or query string.
403 Forbidden. A user has insufficient rights to perform this action.
404 Requested entity not found.
409 Conflict. The request could not be processed because of a conflict in the request.
412 The precondition failed. The request could not be processed because of a conflict in the request.
424 Failed dependency. The request failed due to the failure of a previous request.
500 Internal server error. TargetProcess messed up.
501 Not implemented. The requested action is either not supported or not implemented yet.
503 Service unavailable. Unavailable service because the rate limit was exceeded.

Error object

The response contains detailed information about the error.


A validation error:

    "message":"Validation error",
    "description":"Project.owner - NotNull(may not be null)",
            "message":"may not be null"

Suppress response code

It is possible to suppress the response code for the primaERP API by adding a query parameter.



If this parameter is set, the API will always return status 200 and the response will contain the error object with more information.

This option should be used with a limited functions client e.g. Flash or JavaScript.

If it is an JSONP, the API should always use the error object query. Rendering the JSONP without this functionality will make the API unreliable.
