• PHP 5.3
• MySQL database

1. Create new database (using mysql command, phpMyAdmin, etc.)
2. Run mysql.sql on database (using mysql command, phpMyAdmin, etc.)
3. Edit config.php with database info and API location
4. Site should up and running. Go to index.php in browser

#Updating

1. Replace all files except config.php
2. Run relevant part of diff.sql from your current version

API is called on api.php. This is located at http://api.synccit.com/api.php. If not using synccit.com, this should be shown on devices page.

Basic idea. When someone clicks on a link on reddit, the ID of link clicked is sent here. When someone clicks on a comment thread, the number of comments that thead has and it's ID is sent here. So when looking at reddit later, no matter what device, the link will show up read and if there are any new comments.

The API includes 2 variables. The API version and revision. The version is only changed when major changes to the API occur and will break older uses of it. The revision is for smaller changes. This usually means adding features or small changes that don't break any older use of the API.

To determine the version and revision of the API being used, check the headers sent by api.php. curl -I http://api.synccit.com/api.php gives me X-API: 1 and X-Revision: 8. To see how revisions change, you can check the api.php history.

Auth code and passwords

For added security, instead of using the account password for each call, it uses an auth code. These can be created and deleted from the devices page on synccit.com. Auth codes are currently 6 character randomly generated strings.

For ease of use on the user's side, accounts can be created and auth codes added via the API. This can allow someone without an account to be up and running with synccit within a few seconds.

• Name you want to appear as, such as synccit-userscript or iReddit
• devauth
• developer authentication
• Note: Not implemented yet. This will allow you to ensure only you can use your developer name
