How to specify string in HTTP Call


I am doing HTTP Call to search for sheets that match the specified sheetName. I have several sheets that were created by Smartsheet Control Center that contain the text "Master Schedule".

Query URL (pass):"Master"

When I search for sheets containing the word "Master", this returns the list of "searched" sheets (pasting one such result from the array):


    "contextData":["workspace > folder"],



    "text":"Master Schedule"


If I change the search query to "Master Schedule" instead, it does not return anything

Query URL (fail):"Master Schedule"

How do I specify this search query? I tried all sorts of things like escaping quotes, but it did not work.
