Do we have any documentation on syntax for these filters given
Basically they are odata wueries you can check here
Find the field you want to filter and then use any expression you want
Cheers
And these need to be passed in direct endpoint or can we pass it in parameters?
You can add directly as variable in the endpoint
or
you canc reate url segment parameters and add the those in the end point and pass the filter options in the url segment
"<OrchURL>/odata/QueueItems?$filter=OrganizationUnitFullyQualifiedName eq '" + varFolder + "'"
or
"<OrchURL>/odata/QueueItems?$filter=OrganizationUnitFullyQualifiedName eq '{FolderName}'"
and now add a input argument in url segment with name filename and assign value to it
Hope this helps
cheers
