HTTP Request does not send authorization info correctly

Help Activities

I have to use a HTTP Request Activity to call an api.
It uses simple http authentication, but the reponse is “Authentication data missing”
I have tried not selecting the authentication in the activity, and base64encoding it my self, and adding it to a variable that i can use in multiple calls.

everything i’ve tried gives the same result, except when i do it in postman it just works.

I am pretty new to UiPath, having mostly worked in BluePrism before.

The image shows an HTTP Request Wizard interface with configurations for sending a GET request to an API endpoint, including parameters for authorization and project settings. (Captioned by AI)

The image shows an HTTP Request Wizard configuration window with options for setting endpoint, SSL verification, timeout, request method, parameters, and authentication details. (Captioned by AI)

Gives me this result.
Status 401
“{"detail":"Anmeldedaten fehlen."}”

Hi @lasr

It’s indicates that the server is rejecting your request due to insufficient or incorrect authentication. Verify that you are using the correct authentication method required by the API or test in POSTMAN.

The image displays an error message for a 401 Unauthorized status, listing possible reasons such as an invalid product license, improper request headers, expired user sessions, and outdated API keys. (Captioned by AI)

Thanks for your reply.

In postman i get an answer using Basic Auth.
With the same information as typed into the simple HTTP authentication in UiPath.

I will try to look into your suggestion

@lasr Try to copy the cURL code snippet from Postman and import in Http Request activity.

Hi @iampnkz

Thanks for your reply.

I have tried to copy the cURL from postman and it gives the exact same result.

Does anyone know if i somehow can see the request being sent.
That is possible in Blue Prism, that could perhaps help me track down why my login info is not being sent or declined.

Hey @lasr

If you mock the data for a test, you can use a website like https://webhook.site to investigate how the requests look like when sent from studio and from postman for a comparison.

@loginerror

I actually fixed it. Not sure why yet.
But here is what worked.
The username and password could not be variables, even if they are the same it wont work.
Also i had to end the endpoint with ‘/’ for it to work, otherwise it rejected my login credentials.
Also the project had to be an ‘UrlSegment’ but it works and i am not touching that again till it breaks :smile:
