1b. Authenticate (On-Premise) Orchestrator API

Hi,

i’m trying to authenticate to the orchestrator via API, using Postman. I inserted [myOrchestratorURL]/api/account/authenticate, then the credentials, following what found in https://postman.uipath.rocks/?version=latest#07dbc895-0d81-4867-b6b5-5eb83ade9c03.
I get a positive response but instead of the expected answer

This is simply the logo of the UiPath orchestrator.
Can someone explain to me why I got this answer?

Usually that page appears when the request is redirected after an error, so you might want to double-check the URL and the parameters.
