Dear,

I think you need to have your custom inbox.
No OOTB action for this.

And what if you have a Flexi Task with more than two outcomes (ex: Approve, Reject, Request Amendments?)...In  this case you need to build a custom drop down/radio buttons...

Regards

Hi,

Yes, We have Flexi Task with more than two outcomes (Approve , Reject and More Information required).

Is there any  document to build custom drop down/radio buttons to achieve this ?

Thanks

You can benefit from  "SiteURL/_vti_bin/NintexWorkflow/Workflow.asmx" and build a custom SharePoint WebPart.

Regards

We can build custom web part but this is not we need. We need Click event on Flexi Task action in OOTB preview.aspx page.

Dear,

No OOTB action for direct approval.
The quickest OOTB action in preview.aspx to respond to your task is to click on "Respond to task" link.

Regards,
