I am attempting to use the API to pull a listing of our requestors.  I am receiving the error: {"operation":{"result":{"status":"Failed","message":"Invalid URL","error_code":4007}}}

I am using the url:  https:// sdpondemand.manageengine.com /api/json/requester&scope=sdpodap&authtoken=AUTHTOKEN=f529251b703b3f17f0b198f78960dd6f&OPERATION_NAME=GET_REQUESTERS

Can someone please assist me in where I am wrong?

Thank you

Kate
