HTTP authentication

Question

I am trying to do an outbound http call to Freshservice. It requires basic authorization, but it only uses an api key. Below is the code I use when I do this in PowerShell. How do I replicate this in Logic Apps.

PoweShell code:
$APIKey = 'xyz'
$EncodedCredentials = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $APIKey,$null)))
$HTTPHeaders = @{}
$HTTPHeaders.Add('Authorization', ("Basic {0}" -f $EncodedCredentials))
$HTTPHeaders.Add('Content-Type', 'application/json')

This is what I have tried, but I get:
"code": "access_denied",
"message": "You are not authorized to perform this action."

Answer 1

Hi ,
This worked for me:

according to their doc, auth is basic (https://developer.freshdesk.com/api/#authentication)

one good trick to help is importing the curl in postman

I noticed postman converted into an authorization header that ignores the password, only the work Basic followed by the key. somehow works. the password is made up anyway according to the doc

update worked just as well:

In case someone wants to use the base64 encoding then they can leverage the base64 logic app function.
You can always refer to this workflow expression functions in Azure Logic Apps document that has the list of supported expression functions.
