Create sticky note
Create one or more sticky note widgets on a mural. Each sticky note must be a properly structured object with required x and y coordinates. Pass the 'stickies' parameter as a direct array of objects - NOT strings, NOT nested objects. Example usage: { "muralId": "mural-id-here", "stickies": [ {"x": 100, "y": 200, "text": "First note"}, {"x": 300, "y": 400, "text": "Second note", "shape": "circle"} ] }
