You would like to query the deleted Performance Forms via API (OData API - entity FormHeader).
SuccessFactors Performance OData API
You will need to include one additional permission to see the deleted Performance Forms data.
Find below the path to include this permission:
- Admin Center >>> Role Based Permission >>> Administrator Permissions >>> Manage Documents >>> check the option "Include Deleted forms in Forms ODATA API" to fetch the deleted forms.
After that, you will see the results in your API (example query http://<hostname>/odata/v2/FormHeader?$format=json) with the "formDataStatus=4"
Text from handbook "The formDataStatus is set to '4' when the forms are deleted by the user, or by using the Delete Forms admin tool.".
