Need some help with API call Power BI

so i have an API link to get data, it requires simply a post command with the api link and some body information

the body info is as followed:

This works fine in Postman and I get the data in JSON format, but im curious how i can do the same in Power BI. Any help is appreciated

Also a second thing would be to make a script to receive the access token (the priority goes out to the one above)

It's a simple Post login link where the body is as follows:

So the password and username and domain is given in the body, not in the authorization tab in Postman.
