passing parameter using Proc http get method.

I am attempting to kickstart a job on an API. I am able to get a valid response without sending the _since parameter in the below curl command.

curl -X GET 'https://api.bcda.cms.gov/api/v1/Patient/$export?&_since=2020-02-13T08:00:00.000-05:00' \
	-H "Accept: application/fhir+json" \
	-H "Prefer: respond-async" \
	-H "Authorization: Bearer {access_token}"

Here is my Proc http procedure, alos i have tried passing the _since parameter using IN but no success.

Link for API documentation:https://bcda.cms.gov/build.html#requesting-since-with-Patient

	proc http         		
			url="https://api.bcda.cms.gov/api/v1/Patient/$export"         
         	out=jobresp
        	method="GET"
         	headerout =jobhead;
            headers "Accept"="application/fhir+json"
        			"Prefer"="respond-async"
        			"Authorization"="Bearer &access_token. ";
		run;

Do you have a working curl command or not? Your text says you were able to use curl without SINCE parameter, but your example CURL command syntax appears to have the &_since= in the URL. And your example SAS code does NOT have that parameter.

If you want to pass a URL with &_since in it then quote the string using single quotes to prevent the macro processor from trying to evaluate &_SINCE as a reference to a macro variable.

proc http         		
  url='https://api.bcda.cms.gov/api/v1/Patient/$export?&_since=2020-02-13T08:00:00.000-05:00'
  out=jobresp
  method="GET"
  headerout =jobhead
;
  headers
    "Accept"="application/fhir+json"
    "Prefer"="respond-async"
    "Authorization"="Bearer &access_token."
  ;
run;
