To add web forms to your Canvas course, you’ll need to use the Iframe embed code. Also, you’ll need 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.
Note: If you use a Platinum plan or higher on 123FormBuilder, you don’t need to change the code. Just enable the SSL connection to your web form under Connection Type in the Publish section. Paste the Iframe code in your Canvas page (HTML view) and save your changes. All form data will be saved in the Submissions section of your form, in your 123FormBuilder account.
