Examples of HTTP Request using Digest autentication

Help
1

Hi

I’m trying to consume an API that uses Digest as authentication method, but I keep getting status code 401 - Unautorized.
Iv’e tried passing my username and password both as simple authentication and as parameters in the call.

Can anyone give xaml examples on how to access a webservice that requires Digest MD5 authentication.

Getting access through SoapUI works flawlessly.

@Michaeljep - have you tried with postman? if yes - can you share both postman & http request-> properties screenshots?

I haven’t tried Postman, I use SoapUI instead. But there the connection works great.

are you passing the same details in http request body ?
and the input accept type as xml?

7

Yes to both, the body is exactly like that, just send through made as a string in " ".

8

can you share the http request activity properties?

9

I have tried adding the username and password in both, Headers; Parameters and as simple autentication, but none of them is working.

The only Header that is being sent is the SOAPAction.

Hi

Any input on this? I’m totally stuck - It really strange that I get access through SoapUI but not when trying the same through Uipath.

12

@Michaeljep - can you pls add in accept-encoding as gzip, deflate in headers

13

you lost me there, is it done inside Studio or?

14

@Michaeljep - there could be some headers missing between soapui & uipath
Can you run fiddler and execute api in soapui & http request - get the complete header/body details … based on that we can set the correct/missing objects in uipath httprequest.

example of details -
Get/Post https://example.com/request.service HTTP/1.1
Pragma: no-cache
Accept: application/json
User-Agent: RestSharp/105.0.1.0
Content-Type: application/json
Content-Length: 319
Accept-Encoding: gzip, deflate
Connection: Keep-Alive

Hi GBK

Can it be done without Fiddler as I can’t install it on the server :frowning:

This is the RAW details and log info from SoapUi, maybe that gives a clue of what to do next.

And this shows that the server is challenged to get access.

I managed to run the requests in Fiddler, but it doesn’t really help me. There is nothing in Fiddler that isn’t in SoapUI and Uipath.

@GBK

Any good ideas on how to proceed?

Any one else got some ideas?

Hi GBK

I still haven’t solved this issue, where does it go wrong.

The API I’m trying to access uses Digest - MD5-sess authentication. As I see it, Postman fills in the “missing” headers upon the second request which Uipath doesn’t - at least thats my assumption as I only get a 401 Unauthorized response.

I have tried reading Postmans explanations to the authentication, and tried to type in the missing headers in Uipath, but still no luck.

Then I have tried as below
Make the request and got the response header
Extracted the WWW-Authentication and assigned it to a variable
image
And send it back in the second request - This time I get an 400 Bad request error instead of 401 unauthorized.

I was thinking if the response header should be split into these fields, instead of the approach I have tried.

Can anyone help on how to approch this API that uses Digest?
