I have an additional value of Derived-Priority-Score
That is of type Integer.
Using the v1 API I have tried an update...:
BODY = "{ ""incident"":{ ""notify_watchlisted"":0, ""notify_customer"":0, ""additional_values"":[ {""Derived_Priority_Score"":999} ] } }"
However this does not seem to be the correct syntax and there is no guideline in the GTA-API documentation.
I have managed to get it working with the following syntax: (written in VBS so "" relates to " when sent)
BODY = "{ ""incident"":{ ""priority_id"":1249847371927527504, ""additional_values"":{""Derived Priority Score"":999} } }"
