I'd expect to see HTTPS being used, but don't see that in the code or in
the HTTP API logs you've posted.

So I am still struggling here... I am able to connect to this API and
receive an Access Token using Postman. However, I cannot seem to connect
successfully from a simple RPG pgm using HTTPAPI (something I use all the
time).
I've even compared the HTTP request in Postman to the HTTPAPI debug
file. I even compared the Base64 encoded "Authorization" in Notepad++.
Differences:
1. Postman has a "cookie"
2. Headers are in a different order
Any ideas? I'm at a complete loss.

Sure...
The clientId and clientSecret are set above this code. I am trying to
get an Access Token.
rc = http_setauth(HTTP_AUTH_BASIC :clientID :clientSecret);
// Get an Access Token
http_debug(*on :FLDR + '/' + inCom + '/http_debug.txt');
URL = 'https://marketplace.walmartapis.com/v3/token';
method = 'POST';
form = WebForm_open();
WebForm_setVar(form :'grant_type' :'client_credentials');
body = WebForm_getData(form);
WebForm_close(form);
Response = FLDR + '/' + inCom + '/token_response.json';
Exec Sql set :uuid = generate_uuid();
Ifs_WriteToFile(logFd:'UUID: ' + uuId);
headerVars.partnerId = '10001667921';
headerVars.uniqueId = uuId;
headerVars.serviceName = 'Walmart Marketplace';
headerVars.acceptType = 'application/json';
rc = http_xproc( HTTP_POINT_ADDL_HEADER
: %paddr(addHttpHeaders)
: %addr(headerVars));
rc = http_req( method
: URL
: response
: *omit
: *omit
: body
: 'application/x-www-form-urlencoded');

Wanna share a code snippet so we can see what you are requesting. I
played with this API a while back and had no issues. Nothing special that
I can recall.
