# Human Review

With the Human Review step, the user can be prompted to review, validate, and edit a text value (*Single Item*) or select and edit multiple values (*Multiple Values*) before continuing a workflow. For example, you could create a list of 5 blog titles for a user to select from, ask the user to review and select the titles to publish with a review step, and finally publish the selected content to your blog. ## Review a Single Item ### What is a Single Item? The single item allows the user to edit the text from a single-line text box:

### How to Configure a Single Item 1. **Label the item:** the label will automatically create the variable name associated with your label. In the example below, we label our item "Blog Title", which also created the variable `blog_title` 2. **Assign the value of the item:** use Liquid syntax to pass the value that you want the user to edit and review. In the example below, this is `{{step_2.output}}` 3. **(Optional) Notify a Slack channel:** choose a Slack channel which will notify users to review the output

## Review Multiple Values ### What is are Multiple Values? Multiple values allow the user to select and edit multiple values at once:

### How to Configure Multiple Values 1. Set up a list of options: 1. **Generate a list:** use an LLM step to generate a list of items, it must be an Array

2. **Label the item:** the label will automatically create the variable name associated with your label. In the example below, we label our item "Blog Titles", which also created the variable `blog_titles` 3. **Assign the value of the item:** use Liquid syntax to pass the list you generated in Step 1. In the example below, this is `{{step_2.output}}` 4. **(Optional) Notify a Slack channel:** choose a Slack channel which will notify users to review the output

## Referencing the Human Review Step ### How to Reference a Single Item To reference a single item from the Human Review step, use the variable corresponding to the label you provided. In this example, we named the item "Blog Title" which created the variable `{{step_3.output.blog_title}}` :

### How to Reference Multiple Values To reference multiple values from the Human Review step, use the variable corresponding to the label you provided. However, unlike referencing a single item, the output of a multiple value review is a list:

In other words, `{{step_3.output.blog_titles}}` from the example above gives the user a list of blog titles. If you want to reference only the first blog title, you would need to modify your syntax to `{{step_3.output.blog_titles[0]}}`. ## Review Session When a workflow reaches the review step, it pauses the execution, leaves the workflow in a pending state for review, and creates a review session where the user can review the content. ### How to Review Output * **For single items,** you can edit the content using *markdown* syntax. * **For multiple values,** you can edit the values and select/unselect them. * After editing you can either choose to accept the reviewed content, or cancel the execution. ### Review in the Test Panel As you test your workflow, you can access the review session by clicking on "Review":

### Review in Real-Time when Running Once When you Run Once, the review session will automatically appear, and your user can review the outputs in real-time:

### Review Asynchronously in the History To review executions asynchronously, you can review them in the **History** tab: 1. Click on **History** to view all executions 2. Filter the **Status** to **Review needed** 3. Click on **View** in the Actions column 4. Click on **Review** to review the output and continue the execution
