We have a partnership with iHeart so submission is pretty easy.
Head over to the Distribution page, scroll to the iHeart section and simply hit
Add an iHeart subscribe button to your podcast page
When you get confirmation that your podcast has been accepted you can add your iHeart URL to display an iHeart subscribe button on your Audioboom podcast page.
If you see any unusual errors you're unable to fix yourself, please create a support ticket and we will do our best to help.
