Sample Codes

Below are a few sample API methods available in the Zoho Desk Java SDK. You can get all module instance from ZDesk class.

SDK initialization and access token generation process

These examples help you to initializate and generate access token from the SDK.

            //The SDK automatically initialized when you try to create a ZohoOAuthClient instance.
            ZohoOAuthClient client = ZohoOAuthClient.getInstance();
            //If no error occurs while generating the access token, oauth token data is generated and stored in the persistence class specified.
            ZohoOAuthTokens tokens = client.generateAccessToken("1000.cb07c247e14dd6005b94a03b141897c2.2e1d87264a743a2f5ec42acc357fe73d"); //self_client_grant_token is passed as arg of the method
            System.out.println(tokens.getAccessToken() + " ::: " + tokens.getRefreshToken());

    //When you call - ZohoOAuthClient.getInstance().getLoginWithZohoUrl(); the SDK starts to get initialized.
    //Then, a valid Zoho account URL is returned, based on your configuration property data.
    response.sendRedirect(ZohoOAuthClient.getInstance().getLoginWithZohoUrl())
}

//After the app permissions are accepted, Zoho calls the redirectURI specified in the property file.
//We assume that the redirect API call comes to this method.
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    String code = request.getParameter("code"); //getting grant_token from request
    ZohoOAuthClient client = ZohoOAuthClient.getInstance();
    try {
        //If no error occurs while generating the access token, oauth token data is generated and stored in the persistence class specified.
        client.generateAccessToken(code);
    } catch (ZohoOAuthException e) {
        e.printStackTrace();
