In addition, you can also try to add the 'relative path' option to your connector if it works:
let
// PART 1: Get Authorization Code
Body =
"{'username':'<MyUsername>','password':'<MyPsw>','scope':['<SelectedScope>']}",
url = "http://XXXXXXXXXXXXXXXXXXXXXXXXXXX/api/login/sso",
GetJson =
Json.Document(
Web.Contents(
url,
[
Headers = [
ContentType = "application/json"
],
Content = Text.ToBinary(Body)
]
)
),
AuthorizationCode = GetJson,
// The previous code correctly returns the Authorization Code
// PART 2: Now I try to Get Access Token passing the Authorization Code, the client_id and the client_secret
// Base64 Encoding
_client = "<client_id>:<client_secret>",
TokenURL = "http://XXXXXXXX.XXXXXXXXXXX.com",
Body2 =
"{'grant_type': 'authorization_code','code': '"& AuthorizationCode& '" }",
Source =
Web.Contents(
TokenURL,
[
Headers = [
ContentType = "application/json",
Authorization = "Basic " & Binary.ToText(Text.ToBinary(_client), BinaryEncoding.Base64)
],
RelativePath="/oauth2/token/",
Content = Text.ToBinary(Body2)
]
)
