Hello Developers,
I am trying to develop the custom connector using M Language with the implementation of oAuth2.0 authentication.
Previously, clientId and clientSecret was accessed from the respective file as:
client_id = Text.FromBinary(Extension.Contents("Client_ID.txt"));
client_secret = Text.FromBinary(Extension.Contents("Client_Secret.txt"));
Now, I am facing trouble to implement the new scenario where user must need to enter the clientId and clientSecret in the parameter to have authentication rather than reading from the respective files.
I have developed the simple parameter UI.
Testing_Type=type function(
client_id as (type text meta[
DataSource.Path=false,
Documentation.FieldCaption ="Client_id"
]),
client_secret as (type text meta[
DataSource.Path=false,
Documentation.FieldCaption ="Client_Secret"
])
) as table meta[
Documentation.Name = Extension.LoadString("DataSourceLabel")
];
How to read those values entered by user?
Thank You!
