Azure Data Factory API Connector - api

Question

I am trying to access an application via API REST but I am stuck in the process using ADF.
Basically this process consists in 2 steps.
1 - Getting a session (https://horizon.akixi.com/CCS/API/v1/session)
2 - Authenticating (https://horizon.akixi.com/CCS/API/v1/login?locale=en_GB") using Username and Password.
I have created a Linked Service (Rest) and set the Base URL as (https://horizon.akixi.com/CCS/API/v1/session)
Authentication Anonymous.
Then I create a Data Set to point this API and finally I create a "Copy Data" and tried to set on the Additional Header the authentication's details, but it is not working, I got an error 405.
Basically I can run the below script using Powershell and it is working as expected, but is required to use it on ADF instead.
The script in Powershell is this one.
$user = "xxxxxx#mail.com"
$pass = "123456789"
$secpasswd = ConvertTo-SecureString $pass -AsPlainText -Force
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $user,$pass)))
#Get Session
$url = "https://horizon.akixi.com/CCS/API/v1/session"
$response = Invoke-RestMethod -uri $url -Method Post -SessionVariable se
#Authentication
Write-Host "Authenticating" -ForegroundColor Green
$headers = #{
'Authorization' = "Basic $base64AuthInfo"
}
$headers
$url = "https://horizon.akixi.com/CCS/API/v1/login?locale=en_GB"
$response = Invoke-RestMethod -uri $url -Headers $headers -Method Get -WebSession $se
#List Reports
$url = "https://horizon.akixi.com/CCS/API/v1/report"
$response = Invoke-RestMethod -uri $url -Method Get -WebSession $se
$response
Thank you all.

As the 3 steps are separate, and only the last one fetches data, you should break up the process into multiple activities.
Use Web Activity for the first two steps,
https://horizon.akixi.com/CCS/API/v1/session
https://horizon.akixi.com/CCS/API/v1/login?locale=en_GB"
extract the session variable or Authentication from the web activities. Pass it to the copy activity. The copy activity should target
https://horizon.akixi.com/CCS/API/v1/report
