If you don't mind getting down with a little bit of code, you can install Wisp directly without too much stress. All you have to do is copy and paste a single script in the right place.
Seriously. Here are the steps.
Grab your Wisp Script
In your Wisp admin, go to Settings, and then Setup. Once you're there, look for the code snippet under Other User. Copy the entire snippet.
Add the Wisp Script to your Site
Once you have copied the script, place it directly before the
</body> tag of your website code. Save your edits.
Test your Installation
Verify that the setup was successful.
In the Wisp admin, head to Settings, and then open the Widget section. For now, make sure you’ve selected Floating Button. This will allow us to test Wisp and prove that it’s working correctly.
Once that's done, load up your site or hit refresh. You should see the floating button on your page. It should look something like this:
If it's there, nice work! Your feed is ready to send campaigns, but there are a few other things you might want to consider doing.
Style your Feed: If you want to stick with the floating feed, you can make small adjustments to it. Learn more at Style the Floating Feed.
Supercharge your setup: Add additional targeting options that let you refine your audiences. Learn more at Configure Ecommerce Properties.
Enable Attribution: Make sure you're able to measure the impact of Wisp on your site. Learn more at Set Up Goal Tracking.
