We couldn't authenticate with the credentials provided.

[edoGrammo]

I am trying connecting to a customer integration implementing basic auth. LINK

I have received the integrationID and I have Base encoded my credentials.

I successfully connect by PostMan and by python. 

However, I receive the error "we couldn't authenticate with the credentials provided" when using the following query:

let
Headers = [
#"Authentication" = basic_auth,
#"X-Application-Key" = integrationID],

content = Web.Contents(Instance & sysAPIUrl & ProjectId & "/mail", [Headers=Headers])
in 
content

where Instance, sysAPIUrl, and ProjectId are parameteres I set up.

How may i degub this error in PBI?

Hi @edoGrammo ,

It seems like there might be a typo in your Power Query code. The header for Basic Authentication should be “Authorization”, not “Authentication”.

let
    Headers = [#"Authorization" = "Basic " & basic_auth, #"X-Application-Key" = integrationID],
    content = Web.Contents(Instance & sysAPIUrl & ProjectId & "/mail", [Headers=Headers])
in
    content

Make sure is correctly holding the Base64-encoded credentials in the format .

Best Regards,
Gao
