Suggested refactoring

[BluMichele]

Hi there,

I was working on subscriptions for which there is no API class like SendEmailApi and I noticed that the following logic si repeated multiple times in each API class

// authentication (APIKeyHeader) required
if (!string.IsNullOrEmpty(Configuration.GetApiKeyWithPrefix("Authorization")))
    if (!localVarRequestOptions.HeaderParameters.ContainsKey("Authorization"))
        localVarRequestOptions.HeaderParameters.Add("Authorization",
            Configuration.GetApiKeyWithPrefix("Authorization"));
// authentication (Basic) required
// http basic authentication required
if (!string.IsNullOrEmpty(Configuration.Username) || !string.IsNullOrEmpty(Configuration.Password))
    localVarRequestOptions.HeaderParameters.Add("Authorization",
        "Basic " + ClientUtils.Base64Encode(Configuration.Username + ":" + Configuration.Password));
// authentication (IBSSOTokenHeader) required
if (!string.IsNullOrEmpty(Configuration.GetApiKeyWithPrefix("Authorization")))
    if (!localVarRequestOptions.HeaderParameters.ContainsKey("Authorization"))
        localVarRequestOptions.HeaderParameters.Add("Authorization",
            Configuration.GetApiKeyWithPrefix("Authorization"));
// authentication (OAuth2) required
// oauth required
if (!string.IsNullOrEmpty(Configuration.AccessToken))
    localVarRequestOptions.HeaderParameters.Add("Authorization", "Bearer " + Configuration.AccessToken);

// make the HTTP request

If I might, I suggest creating a new method like AddAuthenticationHeaders in ApiClient and calling it at the beginning of ExecAsync, you are already setting things up from configuration in that location, so why do half the job in ApiClient and half in each method of each API class, move all there 🤷🏻‍♂️.

Also, the code will never enter the third block of if-if-add which is identical to the first.

if (!string.IsNullOrEmpty(Configuration.GetApiKeyWithPrefix("Authorization")))
    if (!localVarRequestOptions.HeaderParameters.ContainsKey("Authorization"))
        localVarRequestOptions.HeaderParameters.Add("Authorization",
            Configuration.GetApiKeyWithPrefix("Authorization"));
