Hi @DevanshuCh ,
I have just checked it does not seem like there is an out of the box API call but it seems that bulk assignment inside Workload balancer is using an internal api which has its specifics when it comes to using it, please check this link and go though the answers to see how to use internal api https://experienceleaguecommunities.adobe.com/t5/workfront-fusion-2-0-questions/fusion-internal-api/... .
There are few important things to mention before using this
- This API can be turned off at any point
- This API can be adapted at any moment
- This API could become official so at some point you might not need custom logic to do this
It is important to weigh in the risks and benefits when using this as it can be a double edged sword.
This is the url used to call the api attask/api-internal/batch, for additional details you can navigate to the developer options in your browser and do one bulk assignment with Workload balancer to see what data you need to achieve this if you decide that the feature is worth the risk.
Hopefully this helps.
Best regards,
Ivan
