Thank you @lgaertner So it seems we have to add this as raw JSON. I was trying to use the URL Encoded parameters which didn't work. I have looked at the API Explorer, it just wasn't clear were I put these parameters.Your method works. Thank youRob

Can anyone provide an example or documentation showing the bulkMove call for opTasks?I can't find anything explaining how it works.Thanks,Rob

Just thought I would write back and let you know that this worked for me. I used Create JSON Thank you again.

Thanks. I'll give that a try and let you know

I'm using a Custom API Call to add issues to Workfront. I'm looking for a simple way to escape unwanted characters. e.g. Double Quotes, tab characters, new line, etc etc. There is the replace function, but nested replaces are getting quite tricky and it doesn't seem to work well in the UI etc.Any ad...

Oh No. I've found the solution, my category ID was actually incorrect.Slightly embarrassing Sorry for wasting your time.Rob

@ChrisStephens That was my initial thought, so I pulled the API name out via the API (POSTMan) then copied and pasted in to Fusion. So just assumed I needed to escape the character. 

@ChrisStephens The updates are in the JSON object in the body of the POST request. e.g. {"name":"test","DE:Paramater Name":"123","DE:Paramater Name 2?":"456"} The name of the parameter here has a question mark. When I submit it, it then tells me it can't find the parameter with that name. 

Thank you for your reply. I'm actually using Fusion (I updated my question). However, I think I tried replacing the question mark with %3F and it didn't seem to work.Rob

I'm making a Custom API Call in Fusion and I'm trying to update a parameter value that has a question mark in the name. Does anyone know how to make this work. I've tried a unicode value an encoded Url value a backslash??Can anyone help? Thank you.
