Set Variables

image: ./set-variables.webP # Set Variables Use this node to set variables that can be accessed from other nodes in the Call Flow. The value can be a static value set as a string (value), a variable from another node such as a request response ( %{request_response.} ), or a call parameter ( %{call.from} ). Access these variables in other blocks with %{} and unset variables with the [Unset Variables](../unset_variables/index.mdx) node. For a more in-depth explanation of using variables, see the [Using Variables](/docs/call-flow-builder/index.mdx#variables) section of our introduction to Call Flow Builder. ## **Node Settings** | Node Setting | Description | |:-|:--| | **Key** | The name of the variable to set. | | **Value** | The value to set the variable to. This can be a static value, a variable from another node, or a call parameter. | ## **Example** Use Set Variables if you plan to use multiple [Request](../request/index.mdx) nodes in the same Flow and you need the variables to carry across the entire Flow. This example makes a request to an API for temperature and location. The request’s response is saved in variables called my_temperature and my_location. In order to make a new request to a new webhook, the Set Variables node is essential because the second Request node will overwrite the request_response. Your first variables will remain accessible using %{vars.my_temperature} and %{vars.my_location}.
