Notify Change Operations

Last modified 26 Feb 2024 07:58 +01:00


Notify Change operation which can be used to "notify" midPoint of some change event which occurred on a resource. This is usable when the actuall communication with the resource costs too many resources, is unsafe, slow or some other factors are against it.


The request is executed as an HTTP POST operation. The request contains the "notifyChange" string as a part of the URI.

Notify Change operation using HTTP POST
POST http://localhost:8080/midpoint/ws/rest/notifyChange


Regarding authorization type, the "Basic" Authorization header should be used.

Authorization header example replace {Base64EncodedCredentials} with the encoded credentials
Authorization: Basic {Base64EncodedCredentials}

To specify the provided content type, please use the "Content-Type" header payload in the body:

Content type header example, other media types are supported as well
"Content-Type: application/json"

You might need to specify the accepted type of content in case you are interested in a format different from xml (default):

Accept type header example, other media types are supported as well
"Accept: application/json"
For supported media types please refer to the following section of the documentation

Supported Media Types


The body should contain a payload consisting of a "resourceObjectShadowChangeDescription" type of object. Please see the examples below for an example of the content in the body of the request.


No options are supported as a parameter for this request.


Error code Meaning


Information. Stay tuned, operation is in progress.


Success. Operation finished successfully. There are two custom codes:

  • 250 for partial error which means that during processing some error occurred but some changes was executed.

  • 240 for handled error which means that there was originally error, but midPoint was able to fix this using its consistency mechanism.

In this two cases, midPoint returns the OperationResult where there details of executed operations can be found.


Redirection or "in progress". This is returned mostly to indicate two cases:

  • Operation has finished, but the results are not in this resource. Redirection is issues to point the client to the results. Typical example is creation of an object with POST to a collection web resource. In this case a new object is created, new URI is assigned and the client is redirected to this URI. Retrieving that URI provides created object and 200 status code, indicating that the operation is finished.

  • Operation is in progress (asynchronous operation). In this case midPoint API redirects the client to a task object that can be used to track progress of the operation.


Client errors. The client has sent request that cannot be processed. This indicates usual situation that are well handled by the midPoint code. Maybe the client request to create conflicting object, delete non-existent object, modification that violates the schema and so on. The OperationResult structure is usually provided in the response to provide more details about the situation.


Server errors. Situations that the server cannot handle and where the cause is unknown. This usually means bugs in the code, insufficient resources such as RAM or disk space, unforeseen failures in the infrastructure and so on. The OperationResult structure might or might not be provided in this case. Some errors are so severe that the structured error information might not be available.

Status codes and the indication of errors and asynchronous processing applies uniformly to all midPoint web resources (both RESTful and RPC).
