Appbroker GetResolvedRequestVariables API API

[fenluo]

Hello 

We tried to use GetResolvedRequestVariables API, but it seems it is throwing out an error message, any thoughts what might be causing it? 

thanks

I can't say as I've ever seen an exception when invoking this API.  Does this happen for all request ID's? You will likely see an exception written out to website.log when the error occurs. Can you please let me know what that exception is? Also, can you invoke the GetResolvedRequestVariables API by going directly to the integraion.asmx page, by hitting the following URL in a browser on the App Broker server: http://localhost/esd/ws/integration.asmx?

Thanks for your reply, yes, invoke the GetResolvedRequestVariables API by going directly to the integraion.asmx page, hitting the url working perfectly, but postman does not work. I went to the  website.log, and here is the error i am getting

I assume the asterisk in your error message was just you replacing the server name for confidentiality reasons?  I just tried this against my test server with no issue.  In my case, I used Postman to issue a GET request to https://servername/esd/ws/integration.asmx/GetResolvedRequestVariables?requestID=3022 with NTLM authentication.  This gave me an HTTP 200 OK response and the expected XML response body.

With this error, there are too many "/esd" in your URL, i.e. /esd/esd/ws/integration.asmx

That isn't the case with the other error you posted, so we'll have to look into that a bit more.

Thanks, I tried with request make sure no duplicate esd, and this time the same error show up, any other log files may have more details? 

thanks,

Thanks everyone's help with this, the reason why is we are getting xml as a return, but we actually need json, so we have json in the header, that's causing the issue. We are just wondering 

what is the exact syntax if we need to make a request to have a return as json? as right now we are only getting xml from this request

[jdempsey · Accepted solution]

These are SOAP APIs that only return XML.  You won't be able to get a JSON response from these.  If you need a JSON response, you would need to write your own web service that calls this SOAP API and then converts the XML to a JSON response.  If you are calling this from PowerShell, it's actually pretty easy to call this SOAP endpoint and then convert the XML response to JSON.  There are numerous examples on the internet showing how to convert XML to JSON in PowerShell.
