Instructions For OneClick On Your Server

Get your email subscribers signed up to your webinar with one click. OneClick will allow you to email your autoresponder list with a special link that when clicked signs them up to your GoToWebinar webinar – automatically.

To get started, you will need to configure a database, run the install program, and register as a developer with Citrix for privileges to use their API for OneClick registrations.


Summary: Create a MySQL database on your webserver. Add a user with full permissions. Move the config_sample.php to config.php. Update the config.php with database name, user and password.

Step 1: Create a MySQL database

From inside your web site’s CPanel, create a MySQL database, ex – gotowebinar.


Step 2: Add a User with Full Permissions

If need be, create a MySQL user and password. Add the user to your MySQL database that you created for OneClick. Be sure to check ALL PRIVILEGES before you click the Make Changes button.


Step 3: Move the config_sample.php to config.php

From inside the CPanel File Manager move the config_sample.php file to config.php in the same directory. Alternatively, you can rename config_sample.php to config.php


Step 4: Update config.php

Edit the config.php file and add your database name, database user and password. The information should look something like: youracc_database, youracc_user, password. Replace $mysql_db = “” with $mysql_db = “youracc_database”, replace $mysql_username = “” with $mysql_username = “youracc_user”, and replace $mysql_password = “” with $mysql_password = “password”.


Summary: Run the install program. Provide a username and password for logging into your OneClick application.

Step 1: Run the install program

Load the install program, ex – and run it.

Provide an email and password, confirm both. Note that the email and password can be different from what you signed up when purchasing OneClick and different from the Citrix API signup that follows.

After successfully installing OneClick, remove the install.php from your webserver.



Summary: You will be registering a free developer account at citrixonline and generating an API key to use with OneClick. You will update your OneClick application with the API key. This is a one time setup.

For the OneClick script on your site, you will need a global GoToWebinar account and not the older GoToWebinar accounts.

How do you know if you have a global GoToWebinar account? When you login to your GoToWebinar account, check the URL address bar. If you see an address that looks like https://global. or https://attendee. then you know you have a global account.
