In UFT one 15.01 version, i have created a service RestAPI test using import WADL from file option.
The API is hosted on Azure.
After importing the API methods, i created activity for get method by dragging it in the test flow.
I can see the input parameters and all. But when i fill everything and send the request then i'm getting status code in the 'Run Step Results' windows as '403-Forbidden'. I have also provide the 'Ocp-Apim-Subscription-Key' and its value by adding request header array under activity property.
Ocp-Apim-Subscription-Key' and its value is same that we use in Azure site while sending the request from there.
Does the server give any explaining reasons for the response message?
Is there any tools have a successful experience, such as Postman?
in any case, the investigation may require more effort. I think you may open a support ticket to have better assist.
