RE: HTTPAPI error on subsequent calls

Ok, testing in more detail.

I have 2 sessions. One works (session 1) and the other was but is failing now (session 2).

Signed off both and back on.

Session 1 I am calling XPO pgm only and works repeatedly.

Session 2, called XPO pgm repeatedly working.
Then called a pgm that calls the 3 other carriers then the XPO. Failed.
Called the XPO pgm only again and fails.

So, the issue must be left over from one of the other calls. All set on LR.
XPO is the only one that uses the HTTP_POINT_ADDL_HEADER but one of the other carriers uses the http_setAuth.

From the good log, there is no Authorization: Basic (key).
In the bad log the Authorization: Basic (key) is there.
I expect that is from the other carrier call.

So, does that mean I should always clear/reset something in each pgm?

When done there will be around 11 calls to carriers web API's.

How do you store your tokens and keep them separate for each of the API calls. It sounds like you're calling a few different ones at different endpoints/servers each most likely having their own tokens.

Have you tried debugging when you get the error, then on a new session where it works, debugging that and then comparing the two for differences?

Nope. It's good for 12 hours. Verified that still good when ran from
second session.

Does the token need to be refreshed? If so, maybe it's expiring
before you're refreshing it?

I am at my wits end.

I am calling the XPO web service.

First thing in the morning I call the XPO pgm and it works, and
keeps working.
I then call a pgm that calls several different web services of
different carriers.
XPO does not work. Returns from httpapi_debug.txt:
Authorization: Basic (bad key)
Authorization: Bearer (token key)


SetError() #13: HTTP/1.1 401 Unauthorized
recvresp(): end with 401
recvdoc parms: chunked 0
SetError() #36: This page requires a user-id & password
http_close(): entered

I then call XPO pgm again and it still fails!

I sign off and back on, still fails!

Now, jump to different green screen session and run XPO pgm, It works!

What the he....ck am I doing wrong?

Code from XPO pgm:

Rc = http_xproc(HTTP_POINT_ADDL_HEADER : %paddr(SetTokenHeader));

** From SetTokenHeader Headers = 'Authorization: Bearer ' +
%Trim(Token) + CRLF; Token comes from a file**

Request = %Trim(TrackingUrl) + '?' +
'&' +
'referenceNumbers=' + %Trim(EntTrackNo);

Rc = http_url_get( Request : ResponseFile);

// Load Response If No Error
If Rc = 1;

Clear TrackingResponse;

// Parse Response JSON Tracking Doc Using YAJL
data-into TrackingResponse %DATA(ResponseFile
: 'doc=file case=any countprefix=cnt_ allowmissing=yes
allowextra=yes')
%PARSER('YAJLINTO');

EndIf;

*InLr = True;
