Overview
The Talend MDM (Master Data Management) Staging Area stores non-validated data. How can you validate the data in the Staging Area? You can do it using a Talend Job and the Web User Interface, as shown below:

Environment
This procedure applies to versions of Talend MDM before 6.0.
Resolution
Talend MDM provides a REST API to perform a staging area validation. You can POST the REST URL, as follows:
-
Create a Job, add a tRESTClient component onto the design workspace, and set the HTTP Method to POST.
-
In the URL field, type one of the following URLs:
-
Run the Job by pressing F6. The Job invokes the Staging Area validation and the Talend MDM server console outputs the following: ![0693p000008uA4QAAU.png 0693p000008uA4QAAU.png](/t5/image/serverpage/image-id/121779i2CB648BA258CD70D/image-size/large?v=v2&px=999)
-
In the Staging Area view of the Web User Interface, you will find 17 records that passed the validation. ![0693p000008uAJtAAM.png 0693p000008uAJtAAM.png](/t5/image/serverpage/image-id/121941i343006CC834CEE8F/image-size/large?v=v2&px=999)
Steps to reproduce the issue
- Import mdmitems.zip (attached) to the studio, deploy all the items to MDM servers.
- Import jobs.zip (attached) to the studio, run the Job loadjob to load the data into the datacontainer Entity in the Staging Area.
- Run the Job tRestClient, it will invoke the Staging Area validation and move the data to the master area.
