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 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 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}.
