Tumblr is the microblogging platform that allows its users to publish text, images, videos, links, quotes and audio as a tumblelog.
To connect Tumblr with Nelio Content, go to the Nelio Content page and click on the Tumblr icon.

Once you select the Tumblr icon, a dialog box will appear in which you will have to select whether you want to connect the Tumblr profile through Nelio Content or through Buffer.

Connect your Tumblr profile directly with Nelio Content
If you have selected the option to connect the Tumblr profile directly to Nelio Content by clicking on the Tumblr icon, and If you are not logged in to Tumblr, a Tumblr floating window will open informing you of the terms and conditions you must accept in order to continue.

You will then be shown the consent screen where you must allow Nelio Content to use your Tumblr profile to post social messages.

Once access to your profile is allowed, the dialog will close and you will see the list of connected social profiles again, which also includes the profile you just connected.

Connect your Tumblr profile through Buffer
Alternatively, you have the option to connect your Tumblr profile through Buffer as explained in the following link:
