To add web forms to your Canvas course, you’ll need to use the Iframe embed code. Also, you’ll need a 123FormBuilder account, a website form builder. Afterward, create and select the web forms you want to publish and go to the Publish → Embed Code section. Copy the Iframe code and log into your Canvas Instructure teacher account.
Next, go to Pages and edit one of your pages or create a new one.
Click on the HTML editor link on the top right side of the content area.
Paste the Iframe code there.
