# Merge study

`POST /studies/{id}/merge`

Start a new job so as to move some DICOM resources into the DICOM study whose Orthanc identifier is provided in the URL: https://orthanc.uclouvain.be/book/users/anonymization.html#merging

## Path parameters

- `id` string, required

## Request body

- object
  - `Asynchronous` boolean — If `true`, run the job in asynchronous mode, which means that the REST API call will immediately return, reporting the identifier of a job. Prefer this flavor wherever possible.
  - `KeepSource` boolean — If set to `true`, instructs Orthanc to keep a copy of the original resources in their source study. By default, the original resources are deleted from Orthanc.
  - `Permissive` boolean — If `true`, ignore errors during the individual steps of the job. Default value is `false`.
  - `Priority` number — In asynchronous mode, the priority of the job. The higher the value, the higher the priority. Default value is `0`
  - `Resources` string[] — The list of DICOM resources (studies, series, and/or instances) to be merged into the study of interest (mandatory option)
  - `Synchronous` boolean — If `true`, run the job in synchronous mode, which means that the HTTP answer will directly contain the result of the job. This is the default, easy behavior, but it is *not* desirable for long jobs, as it might lead to network timeouts.
  - `UserData` object — User data that will travel along with the job.

## Response `200`

- object
  - `ID` string — In asynchronous mode, identifier of the job
  - `Path` string — In asynchronous mode, path to access the job in the REST API
