Hi,
It may have already been asked, but I just can't find it.
How do I add custom http headers, like x-date?
Thanks.

You use the http_xproc API with the first parameter of HTTP_POINT_ADDL_HEADER to specify your custom routine to be called and then build the required header content in that procedure.
Here's how I use it with Zoom APIs - this call has to occur before you invoke the http_string or whatever of the http APIs you are using to invoke the web service.
Code: Select all
// Notify httpapi of the routine to use to add headers
http_xproc( HTTP_POINT_ADDL_HEADER
: %paddr(addSpecialHeaders)
: %addr(authorizationToken) );
The actual addSpecialHeaders() routine looks like this:
Code: Select all
// AddSpecialHeaders
// Called by httpapi to add the headers
// In this case the header is just the authentication token (the JWT)
Dcl-Proc addSpecialHeaders;
Dcl-Pi *N;
headersToAdd Varchar(32767);
var like(authorizationToken) const;
End-Pi;
Dcl-c CRLF x'0d25';
headersToAdd = 'authorization: ' + var + CRLF;
End-Proc;
