Tumblr Settings

What Tumblr supports in Postiz

Character limits, media rules and how these settings appear in the app.

Overview

Every setting on Tumblr is optional: a post with no settings at all is valid. One Tumblr account can be connected as several channels, one per blog, so the destination blog is a property of the channel rather than of the post.

Settings Schema

{
  "__type": "tumblr",
  "title": "Post title",
  "link": "https://example.com/article",
  "sourceUrl": "https://example.com/original",
  "tags": "design, typography, process"
}

Properties

`title`	string	❌	Post title, up to 4096 characters
`link`	string	❌	URL the post links to. Must be a valid URL
`sourceUrl`	string	❌	Attribution URL for reblogged or quoted content
`tags`	string	❌	Comma-separated tags, up to 4096 characters
