http-api how to properly hit a api end point multiple times.

I am trying to optimize this

I have a http api that I need to hit repetitively :

// If Procs is 0, then set debug, set auth
if Procs = 0 ;
http_debug(*ON:'/tmp/gem_GLOC2_debug.txt');
http_setauth(HTTP_AUTH_BASIC: userid: pass) ;
http_xproc( HTTP_POINT_ADDL_HEADER
: %paddr(add_headers) );
endif ;
if Procs = -1;
*inLR = *on ;
return ;
endif ;

msgdata = '{"articles":[{"typeid":1,"articleSecondaryId":+
'+ap2+%trim(itemnbr)+ap2+'}]} ' ;
msgdataL = %len(%trim(msgdata));
rc=http_url_post_raw(
'https://mchporl.xxx.com/LTSystem/+
api/v2/article/search'
:%addr(msgdata)
: msgdataL
:1
: %paddr('INCOMING')
:HTTP_TIMEOUT
:HTTP_USERAGENT
: 'application/json' );

return retdata ;


I would presume that there is a better way for me to iterate a list of item
numbers than
loading my msgdata field and then calling the http_url_post_raw 1000
times...
