[Ftpapi] Problem on subsequent calls

Hi All,

I am calling a web service that requires several steps. Each step returns a string in the header that is used in the URL for the next step. It works the first time I run it, but fails on subsequent calls. By fail, I mean it doesn’t return a 303 return code. If I wait a while (several hours or next day) and call again, it will work on the first call. It runs in Postman every time. Is there a cache I need to clear between calls?

I have attached log files for both scenarios. Logfile1 shows when it works properly. Logfile2 shows a subsequent call. Thank you for looking at this.

// Set credentials

http_setauth(HTTP_AUTH_BEARER: username: passwd);

// Set first URL

URL = 'https://api.adp.com/hr/v2/workers';

// tell it we want async processing and get response.........

callp http_xproc(HTTP_POINT_ADDL_HEADER:%PADDR(AdditionalHeaders));

rc = http_req('GET': URL: *omit: response) ; ç=========This works every time……………

If rc = 202 ;

response = http_header('link') ;

Else ;

http_comp(http_error());

exsr $Exit ;

EndIf;

// now substring out the part of the response header that we want

pos1 = %scan('<': response) ;

pos1 += 1 ;

pos2 = %scan('>': response) ;

link = %subst(response: Pos1: Pos2 - pos1) ;

URL = 'https://api.adp.com' + %trim(link) ;

// use the link to get the URL for the location of the asyncronous server

rc = http_req('GET': URL: *omit: response) ; ç=========This call returns 303 the first time as expected

If rc = 303 ; In subsequent calls rc = 1 and no value in response header

response = http_header('location') ;

Else ;

http_comp(http_error());

exsr $Exit ;

EndIf;

// now use that part of the URL to make the fetch

URL = 'https://api.adp.com' + %trim(response) ;

// get the data to a file on IFS

filename = '/docs/temp/adp0003.txt' ;

rc = http_url_get( url : filename );

if (rc <> 1);

exsr $exit ;

endif;
