Headers With GET Request

Post by emhill »

We are beginning setup with a tax rate company and I wanted to test the connection up front. This "PING" API is supposed to be for checking the connection only and never fail. This is what the site says concerning the request:

Code: Select all

curl
 	-H 'Accept: application/json'
 	-H 'Authorization: Basic aHR0cHdhdGNoOmY='
 	'https://sandbox-rest.avatax.com/api/v2/utilities/ping'
I have my additional headers procedure setup like this:

Code: Select all

P add_headers     B                                 
D                 PI                                
D  headers                   32767a   varying       
                                                    
D crlf            c                   x'0D25'       
                                                    
 /free                                              
                                                    
  headers = 'Accept: application/json' + crlf +     
            'Authorization: Basic aHR0cHdhdGNoOmY=';
                                                    
P                 E                                 
 /end-free
I then have my code to connect to the site like this:

Code: Select all

begsr $ping_avalara;                 
                                     
   http_xproc(HTTP_POINT_ADDL_HEADER:
              %paddr(add_headers));  
                                     
   monitor;                          
     http_stmf( 'GET'                
              : pingurl              
              : resultpath);         
   on-error;                         
     errMsg = http_error();          
   endmon;                           
                                     
endsr;
This is what my debug shows when connecting. I'm getting a timeout it looks like. Not sure if there is some more setup on their end or if I have something incorrect. Would appreciate any help.

Re: Headers With GET Request

Post by Scott Klement »

You are missing a CRLF at the end of your "Authorization" header. The server is waiting for you to send it, and will sit and wait until it times out. Simply add the CRLF to the end of your 'headers' variable and that should fix the timeout.

That said... since both Accept: and Authorization: are fully supported by HTTPAPI, there's no need for HTTP_POINT_ADDL_HEADER for this task. The way you're doing it will work fine -- but, I think it's easier and less error prone to code it like this:

Code: Select all

begsr $ping_avalara;                 

   http_setOption('accept': 'application/json');
   http_setAuth(HTTP_AUTH_BASIC: 'httpwatch': 'f');
                                     
   monitor;                          
     http_stmf( 'GET'                
              : pingurl              
              : resultpath);         
   on-error;                         
     errMsg = http_error();          
   endmon;
Also... I'm assuming that the userid=httpwatch and password=f isn't your real account information. However, please be careful about posting "basic authorization" stuff in a public forum like this! The string aHR0cHdhdGNoOmY= is NOT encrypted, so anyone can go to a website like this one https://www.base64decode.org/ and paste in the string aHR0cHdhdGNoOmY= and see what your userid/password is.

If that really is your userid/password make sure you change it.

Thanks Scott. Adding the CRLF did the trick. This is a sandbox environment right now so I can't really mess anything up yet. Give me time, though!
