You have now generated your Twitter widget at Twitter and you have published the widget code as a File in Canvas. Now, for the last step, you will insert that File into a Canvas Page using the <iframe> tag. Don't worry: you don't have to know any HTML to do this; you can just copy-and-paste the code snippets below, filling in your Canvas File information. (If you are using your own webspace, it's much simpler: you can just use a straightforward URL in the iframe below).

1. Get the File identifiers. While viewing the File in Canvas, copy the URL (address) and look for the two numbers you will see there, along with the name of your Canvas installation. You will need that information later. Here's an example:

https://canvas.ou.edu/courses/56095/files?preview=9923794

2. Create your iframe snippet. To create the iframe you will paste into a Canvas Page, just copy that file information into this iframe code snippet. You can also adjust the width and height as needed; I'm using 450 and 850 because the widget I created at Twitter was customized to be 400 pixels wide and 800 pixels high.

<iframe src="https://___/courses/___/files/___/download" width="450" height="850"></iframe>

3. Insert iframe snippet into HTML Editor. You can now use that iframe snippet anywhere that you see the Canvas HTML Editor. That might be a Page, but it also might be in a Discussion Topic, etc. You will need to click on the HTML Editor link to access the code view, and paste in the iframe snippet. At the bottom of this page, you can see the snippet above at work: it's the Instructure Twitter feed!

And now... here's Instructure at Twitter:
