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.<object_field>} ), or a call parameter ( %{call.from} ).

Access these variables in other blocks with %{<Key>} and unset variables with the Unset Variables node.

For a more in-depth explanation of using variables, see the Using Variables section of our introduction to Call Flow Builder.

Node Settings​

Node SettingDescription
KeyThe name of the variable to set.
ValueThe 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 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}.

Set variables from a request response.
