Hi Osama Alajarmeh,

Sadly, GroupShare does not have the batch tasks exposed at that level of granularity via the Rest API. 

If you don't want to have the file finalized, but still update the translation memory you could use the file download Rest API call (HTTP GET /api/projectserver/v2/projects/{projectId}/download/{type}). 
You need to pass in the query string the following parameters: 

• languageFileIds
• nativeFiles=true (this must be set to true so that "updateTms" parameter is taken into account)
• updateTms

The boolean parameter called "updateTms" will trigger the updating of server-based TMs. Calling the download endpoint will return you an archive with the native file - but the file will not be finalized.

This might be your best option to achieve what you're after. 

Cheers,
Zoltan

Thank you Zoltan!

I've checked the API documentation and apparently the queries you've mentioned refer to an HTTP call without "{type}". Nonetheless, I've tried both as per the documentation, and unfortunately none of them works. The one proposed above with the correct endpoint (without {type}) gives a 500. As for the endpoint with {type}. It gives a 200; however, I've checked the server-TM, and there's no updates.

The same HTTP calls are used by the GroupShare web application when you're downloading the target version of selected files. 

It should be a HTTP GET to api/projectserver/v2/projects/{projectId}/download?languageFileIds={languageFileId}&nativeFiles=true&updateTms=true

Could you check once again and if you don't succeed post the HTTP request, please. 

Unfortunately, it's still the same

Hmm, that should work. Can you check ApplicationService.log file for the error details? From your screenshot I can't see the HTTP error code. 

But, from the look of it the request seems to be composed fine. That is the same request that is used by the GroupShare Web UI, you could inspect that when using the "Download target file -> Include TM Update" option - on the project details page. 

See a screenshot, using Postman: 

I've tried doing the task from Groupshare, the file is downloaded; however, I couldn't see any update tasks in the background tasks.

I've gone through the log viewer on the Web UI and found these errors

You might be calling REST API GET with lanaguagefileid of source file, basically one need to pass languagefileid of the translatable/target file. See below

Please confirm, if this helps

It worked!

How silly of me  I should've paid more attention to the file ID.

Thank you so muchZoltan Balazs  and  Jayaraj Shetty . You are the best!

Osama Alajarmeh glad that it worked!
