  • Error 400 with Unauthorised client

    While trying to access an api, receiving 400 with detail as an unauthorized client. It appears I am trying to send a bad request and somehow the response does not match the request or could be vice versa. Per my understanding, the api requires 5 input, [client_id=YOURCLIENTID , &client_secret=YOURCLIENTSECRET , &grant_type=refresh_token, &refresh_token=YOURREFRESHTOKEN , &scope=openid%20profile] .

    Am I missing anything here?

    ***** Code snippet
    clientid = 'SUPERUSER_9-00_1062';
    clientsc = 'giut67t9v76f9&kyygmpy789hmh87hm8jh8hp78g67g96';
    comm = http_persist_open( URL:timeout);
    data='grant_type=client_credentials'+ '&scope=openid%20profile';
    http_xproc(HTTP_POINT_ADDL_HEADER: *null);
    http_xproc(HTTP_POINT_ADDL_HEADER:%paddr(addHeader s));

    Could you edit this to place your code etc. inside code /code tags please (tags go inside square brackets) that way we can read it.

    Also what is the & in "client_credentials&scope=openid%20profi le: about
    ? I also see an extra blank (as shown) in that string in the log.

      Done. Thank you for correction. Just a copy/paste error, with that extra blank thing. Corrected it.

        The server is responding with {"error":"unauthorized_client"} to tell you that it doesn't like the client information you are sending.

        What you've shown us tells us what doesn't work. In order to help you further, we'd need to know what 'mytestsite.gov' needs in order to work properly.

          Thanks Scott, able to figure out, I was sending header information in Data. Corrected it and receiving a response now.

          Just going off the topic, any other option to schedule calling of a green screen program without actually putting it in scheduler or making it as a Never-Ending Job?

            "schedule calling of a green screen program"

            Why would you want to schedule the running of a 5250 program? Are you hoping to start the program and just wait for a user to arrive? I guess you could maybe use 3rd party PC software to interact with a 5250 client.

              Let's say, I have a report and wanted to have it in my mailbox every Friday morning. To achieve this, I could see 2 options

              1) An entry in job scheduler to call my program every Friday.
              Con: I need this report from the development box and scheduling a job needs in this box required a higher level of access(which I refrain to ask).

              2) Submit a Never ending job that keeps a check if it is Friday, call the report program.
              Con: I have to monitor the job every Friday, if it is up and running, considering there are chances that job may/may not, land in msgw due to some any issue.

              I am not very much interested in using any 3rd party app/soft. And seek guidance from senior members if there is a possibility that's more than meets the eye.

              Scheduling a window service is one possible solution, I could think (bit skeptical, I must say).

                Where does the "green screen program" come in? What you describe doesn't sound like a 5250 (aka green-screen) program to me.

              My bad if I made it look like that, but it's totally RPGLE program I am talking about. Basically, it's the RPGLE program that generates a report(spool) and I want this spool to be mailed every Friday.

              Does that make sense now?

                This has nothing whatsoever to do with the "Error 400" topic of this thread. Please start a new thread.
