At the moment there are only 2 votes for this feature so it doesn’t have a high priority, What you could do for now is use the HTTP Request node. Most of the time if the API documentation has a CURL request in it you can break it down to use it with n8n.
@Jon, yes we could use curl, but all the required features that we currently need are available on the freshservice node except notes, without out this the freshservice node is just doing on way communication that hampers our usage.
I get that, It was more to suggest a temporary work around for you using the HTTP Request node until we (or a community member) get around to adding in support for notes.
