Help Center API limitations with content blocks
Content blocks let authors insert the same content in multiple help center articles. See Reusing content with content blocks in Zendesk help.
Certain articles in the help center may have content blocks and others may not. The Help Center API behaves normally with articles that don't have any content blocks. However, the API has the following limitations with articles that have content blocks.
"body": "<p>This article has content blocks enabled.</p>\n<p>This is a content block.</p>\n<p>This is the rest of the article.</p>"
Even if you make a preliminary GET request to get the
body of an article with content blocks to use in your update, the content blocks are converted to flat text in the GET response. After updating the article, the links to the content blocks in the Guide editor are replaced with the flat text.
Updating any other article or translation property does not affect any content blocks in the article.
You can use the Archive Article endpoint to archive articles containing content blocks.
