The "Human Approval" node allows you to add a human-related check element into your flow. It receives an email address as well as the content that needs to be approved.
The result of the approval can then be used to trigger different nodes.
Email: The email that the approval is sent to
Content: The content that needs to be approved
Example 1: This flow will create a blog post about content marketing which will be send to the user for approval. If the blog post is approved, a document will be created using the content, however, if it is not approved nothing will happen.
Example 2: This flow will create a blog post which will be rephrased immediately. The rephrased content will be sent to the user for approval.
If the content is approved, it will be automatically published to WordPress, else it will be emailed to the user with the subject of "Blog Posts needs editing".
