Variables in Flows
Understand how variables work in flows.
Variables can be used to pass data between blocks.
Inputs are variables that are passed to the flow when it is run.
A block can access:
- input variables
- outputs from previous blocks
- variables defined in code blocks
Blocks that return object type outputs will also have a stringified version
of the block output.
For example, if a block is called search and returns an object, there will
also be a variable called search_str which is a stringified version of the
object.
Accessing Variables
In most blocks / fields, variables can be accessed using curly braces {{var_name}}.
In code blocks, variables can be accessed directly using var_name without curly braces.
