Header is missing:

Code:

["Content-Type"] = "application/x-www-form-urlencoded"

 yes, now i get the authorization code (authCode).

Next is exchaging the authorization code for an access token, see my code try below.
Doc: https://interop.ondilo.com/docs/api/cust...n-exchange

Code:

-- exchange the authorization code for an access token
  if authCode then
    url = apiHost..endpointToken..'?code='..authCode..'&grant_type=authorization_code&client_id=customer_api&redirect_uri='..uri
    method = "POST"
    local response_body = {}
    local res, code, response_headers, status = socket.http.request
    {
      url = url,
      method = method,
      headers =
      {
        ["Content-Type"] = "application/x-www-form-urlencoded"
      },
      source = ltn12.source.string(''),
      sink = ltn12.sink.table(response_body)
    }
    log(res, code, response_headers, status)
  end

but as usually i received an error
