To auto-share your Podbean episodes to Tumblr, you just need to connect your Podbean podcast with Tumblr.
Here are the steps to connect your Podbean account with Tumblr:
1. Log in to your Podbean account and go to the 'Settings'->'Social Share' page. Then click the “Connect to Tumblr” button.
2. A pop up window will ask you to log in to your Tumblr account and give permission to Tumblr; click “Allow”.
It typically takes 30 minutes for the new episodes to be posted to Tumblr.
*Please note that episodes auto-shared to Tumblr can only be played at your Tumblr site https://tumblrusername.tumblr.com.
