I am having trouble formatting the parameters to upload a file through the Box Api using InvokeUrl. I have included a sample Box API request for reference. I'm not sure how to handle the "file" in the request. I have tried many variations without success. I have pasted the code I am using without addressing the "file" in the request. Any help would me much appreciated. I am getting a 400 error code from Box.
