    Hi I created an API message source in ThinkAutomation V5 5.0.898.2, I then set the form action to the Web API URL shown on the Message Source properties.

    When I submit the form I receive a 401 unauthorized error. Allowed origins is blank.

    When I switch the form action to another url , it submit's the form just fine the submission is below:


    {"Accept":"text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,/;q=0.8,application/signed-exchange;v=b3;q=0.9","Referer":"","Sec-Ch-Ua":""Google Chrome";v="107", "Chromium";v="107", "Not=A?Brand";v="24"","User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/ Safari/537.36","Content-Type":"application/x-www-form-urlencoded","Cache-Control":"max-age=0","Content-Length":"188","Sec-Fetch-Dest":"document","Sec-Fetch-Mode":"navigate","Sec-Fetch-Site":"cross-site","Sec-Fetch-User":"?1","Accept-Encoding":"gzip, deflate, br","Accept-Language":"en-US,en;q=0.9","Sec-Ch-Ua-Mobile":"?0","Sec-Ch-Ua-Platform":""Windows"","Upgrade-Insecure-Requests":"1"}



    Any insight?

        Hi Matty,

        Would you be able to perform the same test but report in here the time stamp and time zone so that we can review our logs to find the cause please? We will also need the IP address too so we can review a potential blacklist entry that might be blocking this.

        Thank you

                The issue seems to be caused when the Origins value set against the Message Source is blank (which should allow any origin). We will update the gateway server later today.

                    @stephenparker thanks I will await the update.

                    Any chance the gateway will be updated to be able to respond to HEAD requests at the same time? Use TA Web API as callback url for Webhook events from 3rd party
