<img alt="The String block" src="https://assets.postman.com/postman-docs/v11/flows-reference-blocks-string-v11.53.2.jpg" width="280px" />

The **String** block outputs a sequence of characters that's configured in the block. This can be used in situations where you need to send a static string to the input of another block. For example, you can use a **String** block when you want to set a static parameter to an API request or define a variable.

You can [insert](/docs/postman-flows/reference/blocks/overview/#insert-data-blocks-into-other-blocks) the **String** block into other blocks, such as **Evaluate**, **If**, **List**, **Record**, or **Template**.

## Output

The **String** block has a single output port that sends the string of characters entered in the block.

## Setup

Select the **String** block's text box and enter a string of characters.
