You need to pass the zip file once you've downloaded it thru an "Extract Archive" module.

Can you post your API call? I just tested it with the task constraint set to ASAP, and with all 4 of the duration types, and my body was { "duration": 15 } and that worked.

I was referring the task constraint (edit), i.e. must start on, must finish on, fixed dates, etc. I just did a quick test for duration type Simple, and just providing an integer in the "duration" field updates the duration, with task constraint = As Late As Possible

You need to pass the string from the Typeahead field thru a parse JSON module, and then you can map the ID directly.

Check the task schedule type. Certain schedule types cannot have the duration set.

The only way you would manually be able to do it is if you use a custom API (http) module, and not the native salesforce modules.

The easiest way is to use the "assignMultiple" action module to assign any custom forms you need, as this module will accept a list, and then update your custom properties as a second call.

They do not need system administrator access. If all they are doing is polling for data, then they just need a basic user account that would be able to see that data normally.

You can do something like this if(length(get({variable};1))>1,array,string)

Instead of doing it in a filter, you could just add it as a parameter to your query, to the effect of lastUpdateDate = {today -2}lastUpdateDate_Mod = gt
