SuccessFactors ODATA Services via HCP API Management : Unable to fetch data from catalog

Hi Experts,

I am trying hands-on on the API Management service(HCP trial account) and did create an API provider for a successfactors instance I have account on.

Settings are as below >>

Connection:

Host : apixx.successfactors.com

Port : 443

Path Prefix:/odata/v2

Authentication:

Use SSL :  checked

Authentication Type : Basic

UserName : user@company

password : valid password

This automatically forms the Catalog URL as >> https://apixx.successfactors.com:443/odata/v2, which if I use in the browser , and provide authentication details, it does throw the list of ODATA services so it looks good so far till here. I can also invoke these services from Postman, so there is no issue with respect to the link / user / password etc.

After this step, when I save the API provider and then move to the Manage --> Create API option, and select the recently created API provider and click on Discover(Expectation here is to see the list of ODATA services and to select one) , I always get the  error as shown in image.

Attempt to re-do the operation does only change the request ID(GUID format ID) every time.

Questions >>

1. is there any obvious error in the configuration or anything being missed?

2. the different request ID being generated for every attempt , is it something that can be checked inside logs for more details?

Thanks in advance,

Amol Joshi
