Canvas Integration

Canvas Integration

This page assumes you have followed the Production Start instructions to get a working Canvas installation.

External Services

Amazon S3

You will need an account with Amazon Web Services to store data on Amazon S3. Once you have your account, visit your security credentials page and find your access key id and secret access key. These two values will help authenticate Canvas to your storage container.

Next, visit the S3 Management Console and make sure you have a bucket set up. Note the bucket's name.

To configure Canvas to use your S3 bucket for file storage:

• Open config/file_store.yml, find the production section, and change storage: local to storage: s3, and comment out the path: tmp/files line.
• Open config/amazon_s3.yml, find the production section, and fill in the bucket_name, access_key_id, and secret_access_key fields in with the values you found out earlier.
• Restart both Apache and the automated jobs daemon (sudo /etc/init.d/apache2 restart && sudo /etc/init.d/canvas_init restart).

Canvas uses Uploadify for file uploading, which in turn uses Flash. If you are uploading files to a different domain than the one being used by your Canvas application, you will need to set up a XML cross-domain policy file in your bucket to avoid sandbox security issues. A typical cross-domain policy file looks like this:

<cross-domain-policy>
<site-control permitted-cross-domain-policies="master-only"/>
<allow-access-from domain="yourdomain"/>
</cross-domain-policy>

You can read more about cross-domain policy files here.

Facebook

• Browse to the Facebook plugin settings at http://<your-canvas-domain>/plugins/facebook
• Follow the instructions there.

Google Docs

• Register your instance of Canvas with Google.
• Copy config/google_docs.yml.example to config/google_docs.yml and open it up. Find the production section of the configuration file and input the OAuth consumer key and OAuth consumer secret registering with Google gave you.
• Restart both Apache and the automated jobs daemon (sudo /etc/init.d/apache2 restart && sudo /etc/init.d/canvas_init restart).

Kaltura

You will need an account either at Kaltura.com or with a self-hosted instance of Kaltura.

• Navigate to http://<your-canvas-domain>/plugins/kaltura. This is where you'll fill in the values below.
• Go to the management console and click the Settings tab.
• Under Integration Settings you'll find most of what you need, including partner id, subpartner_id, secret_key (administrator secret) and user_secret_key
• You can specify any player_ui_conf that you want. For custom-built players (check out the Studio tab) you can see the id in the UI.
• For kcw_ui_conf and upload_ui_conf there's not a good solution to get this in the UI. If you're hosted on Kaltura.com check out the Kaltura uploading guide and the uploader widget page for some useful defaults. If you're self-hosted you probably know how to (or hopefully can figure out how to) set up your own ui_confs.
• Restart both Apache and the automated jobs daemon (sudo /etc/init.d/apache2 restart && sudo /etc/init.d/canvas_init restart).

For more detailed information about setting up Kaltura, please see our Kaltura setup instructions.

Linked In

• Set up a developer accounts with LinkedIn and get your developer API key and secret key. You'll need to fill out the details of your integration. You don't need to enter an OAuth Redirect URL.
• Copy config/linked_in.yml.example to config/linked_in.yml and open it up. Find the production section of the configuration file and correct the configuration file to have your API key and API secret.
• Restart both Apache and the automated jobs daemon (sudo /etc/init.d/apache2 restart && sudo /etc/init.d/canvas_init restart).

Scribd

• Set up a developer account with Scribd and get your developer API key.
• Copy config/scribd.yml.example to config/scribd.yml and open it up. Find the production section of the configuration file and correct the configuration file to have your API key and API secret.
• Restart both Apache and the automated jobs daemon (sudo /etc/init.d/apache2 restart && sudo /etc/init.d/canvas_init restart).

TinyChat

• Set up an account with TinyChat and get a developer API key.
• Once you have an API key, copy config/tinychat.yml.example to config/tinychat.yml and open it up. Find the production section of the configuration file and replace api_key: key with api_key: <yourkey>.
• Restart both Apache and the automated jobs daemon (sudo /etc/init.d/apache2 restart && sudo /etc/init.d/canvas_init restart).

Twitter

• Register your instance of Canvas with Twitter.
• You'll need to specify the Registered OAuth Callback URL as http://<your-canvas-domain>/oauth_success?service=twitter.
• Make a note of your consumer key and consumer secret.
• Once you have these keys, copy config/twitter.yml.example to config/twitter.yml and open it up. Find the production section of the configuration file and replace api_key: key with api_key: <your_consumer_key> and secret_key: shared_secret with secret_key: <your_consumer_secret>.
• Restart both Apache and the automated jobs daemon (sudo /etc/init.d/apache2 restart && sudo /etc/init.d/canvas_init restart).
