    // We demonstrated how to get an access token for your Azure Key Vault
    // in this example: Azure Key Vault Get OAuth2 Access Token using Client Credentials

    // However.. starting in Chilkat v9.5.0.96, instead of directly providing Chilkat with the OAuth2 access token,
    // you can instead provide the means for Chilkat to automatically get the OAuth2 access token,
    // and in addition, Chilkat will automatically re-fetch a new OAuth2 access token as needed, such as shortly 
    // prior to or after expiration.

    // You do this by setting the AuthToken property to a JSON string that contains the required information.

    let json = CkoJsonObject()
    json.UpdateString("client_id", value: "APP_ID")

    // The APP_PASSWORD is the "password" returned by the Azure CLI command: az ad sp create-for-rbac --name http://example.com --role Contributor
    // See Azure Key Vault Get OAuth2 Access Token using Client Credentials
    json.UpdateString("client_secret", value: "APP_PASSWORD")

    // The access token will be for Azure Key Vault operations.
    json.UpdateString("resource", value: "https://vault.azure.net")

    // Specify the token endpoint which includes your tenant ID.
    json.UpdateString("token_endpoint", value: "https://login.microsoftonline.com/TENANT_ID/oauth2/token")

    let http = CkoHttp()

    // Instead of providing an actual access token, we give Chilkat the information that allows it to 
    // automatically fetch the access token using the OAuth2 client credentials flow.
    http.AuthToken = json.Emit()

    // Replace key_vault_name with the name of your Azure Key Vault.
    let sbResponse = CkoStringBuilder()
    var success: Bool = http.QuickGetSb("https://key_vault_name.vault.azure.net/certificates?api-version=7.4", sbContent: sbResponse)
    if success == false {

        var statusCode: Int = http.LastStatus.intValue
        if statusCode == 0 {
            // We did not get a response from the server..
            print("\(http.LastErrorText)")
        }
        else {
            // We received a response, but it was an error.
            print("Error response status code: \(statusCode)")
            print("Error response:")
