Your Cbox embed code is available at your control panel. You need this code to install your Cbox on your website.

Also on that page is your Quick Link — a URL which you can use to access your Cbox directly in your browser or on your mobile device.

Once you have created your Cbox account, go to the Publish page of your control panel. The code and steps for embedding your Cbox are provided there for a number of common platforms.

If you install your Cbox and all you see is code, or nothing at all, your web host may be removing or otherwise interfering with the HTML iframe tags that Cbox uses. Your Cbox code needs to be pasted into an area of your site that accepts HTML without modification. This may mean switching your editor from "rich text" or "WYSIWYG" mode into HTML-editing or "raw" mode, or you may need to open your template files in a plain-text editor like Notepad.

Remember that you always have the option of posting or sharing your Cbox Quick Link — this gives visitors direct access to your Cbox in a full-screen layout, so it's perfect as a mobile option or for stand-alone use.

Go to the Theme editor in your control panel. There you can specify the fonts and colours of your Cbox, using a point-and-click editor. You can always reset your theme to one of the preset defaults there, if you would like to start again.

If you have a Premium or Pro Cbox you can edit CSS, which gives you complete control over presentation.

If you have a Premium or Pro Cbox, you can create a moderator name for yourself at your Users page, and then log in on your Cbox using the "profile" link. You will see a delete icon [x] next to each message in your Cbox, and you will not have to log in at your control panel at all to delete messages.

Alternatively, visit your Messages page to delete messages individually or in bulk. Deleted messages are removed from your public Cbox history, but are preserved in your Archives.

Yes. In the Theme editor, simply delete the colour codes for the main and form background ("BG") elements. This will make the Cbox transparent, allowing whatever is behind the Cbox to show through.

Note that any pop-ups generated by a transparent Cbox will have the default background colour — usually white. If your font colour is light, it may be invisible in popups. You can fix this by editing the CSS to introduce a background-color rule for popups.

The option "Enable site whitelist" at your Publish page will prevent other websites from displaying your Cbox to their visitors.

When using this option, ensure the web address we have on record (also on that page) is the simplest possible address for your site. For example you should generally not include the "www." part nor any trailing path, like "/index.html".

You can register a bot user at your Users page. Bot users are like ordinary registered users, except that instead of a password they are issued an access token. You cannot log in via the normal profile dialog. Instead, you can use the token directly in HTTP requests to Cbox.

We do not currently support an official API, but to demonstrate how you might read and post to your Cbox using a bot, the proof-of-concept PHP script below takes a simple HTTP-based approach. Run this script on your own server, and your bot will post to your Cbox. After its initial message, it will poll for messages containing trigger words, to which it will respond.

You can run the script from a shell, or have it run automatically with a crontab entry. When it's running, test it by entering a message in your Cbox such as "hello bot", "time?", or "what is the weather in new york?"

You can downgrade from Pro to Premium at your control panel. Your Pro features will be disabled automatically.

If you let your Premium plan lapse, it will not automatically revert to a Free Cbox. Your messages and settings will be saved but your Cbox will be locked. You will be able to renew at any time reactivate it. To get back on the Free plan, simply sign up for a new Cbox, using a new Cbox name.

If our service is not meeting your expectations on any plan, please contact us and we will do what we can to improve your experience.

You need to have cookies enabled in your browser in order to use the control panel. Your browser may be configured not to accept cookies, or it may be in a "private browsing" mode, or you may have a plugin or extension that is restricting them. Test in another browser if possible.

The most likely reason for this is that it was delayed, or trapped by a spam filter. Check your spam folder in your email client. If emails from Cbox are repeatedly being marked as spam, try adding our addresses to your email client's address book.

It's also possible the email address we have on record for you is wrong. If you know your account details, log in and check your email address is correctly spelled.

Finally, you may want to contact us from another email address for further assistance.
