I am struggling to generate the exact Request Content body for a REST API request in SharePoint Online (Create item in a folder). As directed by Microsoft, the API call needs to look like this https://docs.microsoft.com/en-us/sharepoint/dev/sp-add-ins/working-with-lists-and-list-items-with-rest#create-list-item-in-a-folder
Using "Call HTTP Web service" action, we need to specify a Dictionary as the request content. How do I create this body using the dictionary, specifically the "formValues" as it contains square brackets? I understand others are possible using a Dictionary as an input into another Dictionary.
