Referencing the Canvas SDK

The Canvas SDK is available on GitHub, and you have two options for referencing it from your canvas app.
  • Host the SDK on your own Web server and access it there
  • Access the SDK hosted on the Salesforce server
For example, here’s what the include statement looks like if you host the SDK on your own Web server:
1<script type="text/javascript" src="/sdk/js/canvas-all.js"></script>
Here’s what the include statement looks like if you reference the hosted SDK:
1<script type="text/javascript" src="https://<instance>.salesforce.com/canvas/sdk/js/66.0/canvas-all.js"></script>

The ability to reference the SDK on the Salesforce server is useful when you want to include one of the SDK files in a Web app or from a Visualforce page.
