Flow variables and resources
Key Takeaway
A variable holds a value the flow can change, and each time the flow runs, every variable starts at its Default Value.
Flow resources are the named values a flow can reference while it runs. The most common resource is a variable. Together with elements and connectors, resources are one of the three building blocks of every flow. You create some resources yourself, the system provides others, and Flow Builder creates some automatically when you add elements.
The three building blocks of a flow
Every flow is built from three things:
- Elements are the actions, such as Get Records or Assignment.
- Connectors are the paths between elements.
- Resources are the values that elements read, calculate with or pass along.
