bad authorization header

[jmawebtech]

Hi,

Can you help with this error?

Here is my code:

    public SquareProvider(string merchantId, string applicationId, string applicationSecret, string accessToken)
    {
        Configuration.Default.AccessToken = accessToken;
        Configuration.Default.ApiKey.Add("Authorization", applicationSecret);
    }

    public RenewTokenResponse Authenticate()
    {
        RenewTokenResponse response = new RenewTokenResponse();

        try
        {
            SearchLocations();
        }
        catch(ApiException)
        {
            response = RenewToken();
            accessToken = response.AccessToken;
        }

        return response;
    }

    public RenewTokenResponse RenewToken()
    {
        OAuthApi apiInstance = new OAuthApi();
        RenewTokenRequest body = new RenewTokenRequest();

        RenewTokenResponse result = apiInstance.RenewTokenAsync(applicationId, body).Result;

        return result;

    }
