There are several types of Flow Resources available:
**Variables** are the most common resource type, storing single values like text, numbers, dates, or record data. They can be configured as input, output, or both, allowing data to pass into and out of the flow.
**Collections** store multiple values of the same data type, similar to arrays or lists. Collection variables are particularly useful when working with multiple records retrieved from database queries.
**Constants** hold fixed values that remain unchanged throughout the flow execution. They provide a centralized location for values used repeatedly, making maintenance easier.
**Formulas** calculate values dynamically using Salesforce formula syntax. They recalculate each time they are referenced, ensuring current values based on other resource values.
**Text Templates** allow you to create formatted text blocks with merge fields, ideal for constructing email bodies or creating dynamic content.
**Choice Resources** define options for screen elements like radio buttons, picklists, or checkboxes. Record Choice Sets dynamically populate options based on database queries.
**Stages** track progress through guided processes, particularly useful in screen flows where users move through multiple steps.
Flow Resources can be created manually or generated automatically when certain elements are added to your flow. For example, Get Records elements automatically create record variables or collections.
Proper resource management is crucial for flow performance and maintainability. Naming conventions should be clear and consistent, making flows easier to understand and troubleshoot. Resources can be viewed and managed in the Flow Builder's left panel under the Manager tab, where administrators can create, edit, and delete resources as needed for their automation requirements.

Why Flow Resources Are Important
Flow Resources are fundamental building blocks that enable Flows to store, manipulate, and reference data throughout their execution. Understanding resources is essential for building efficient, maintainable automation solutions. As a Salesforce Administrator, you'll use resources constantly when creating Flows, and they appear frequently on certification exams.
What Are Flow Resources?
Flow Resources are elements within a Flow that hold values, define collections of data, or provide reusable components. They act as containers for information that your Flow needs to process, reference, or output. Resources exist only during the Flow's execution (with some exceptions) and help you build dynamic, flexible automation.
Types of Flow Resources
Variables - Store single values of a specific data type (Text, Number, Date, Boolean, Record, etc.). Variables can be set as available for input, output, or both, allowing Flows to receive and pass data.
Collections - Store multiple values of the same data type. Record Collections hold multiple records, while Text Collections or Number Collections hold multiple primitive values.
Constants - Store fixed values that cannot be changed during Flow execution. Useful for values referenced in multiple places that might need updating later.
Formulas - Calculate values dynamically using formula expressions similar to formula fields. They recalculate each time they're referenced.
Text Templates - Store formatted text that can include merge fields from other resources. Ideal for email bodies or rich text content.
Choice Resources - Include Record Choice Sets, Picklist Choice Sets, and individual Choices for use in Screen elements.
Stages - Define the stages in a guided process for Screen Flows.
How Flow Resources Work
Resources are created in the Flow Builder's Resource panel or automatically when you configure certain elements. When a Flow runs:
1. Resources initialize with default values or remain null 2. Assignment elements or element outputs populate resources with values 3. Resources can be referenced in element configurations, conditions, and formulas 4. Output-enabled variables pass data back to calling processes
Key Concepts to Understand
Data Types - Each resource has a specific data type. Record variables store a single record of a specific object type. Text variables store string values. Choosing the correct data type is critical.
Availability for Input/Output - Variables marked as "Available for Input" can receive values when the Flow is called. Those marked "Available for Output" can pass values back to calling processes.
Collection vs Single Value - Understanding when to use a collection versus a single-value variable is crucial. Get Records returning multiple records requires a Record Collection variable.
Null Values - Resources can be null (empty). Always consider null handling in your Flow logic to prevent errors.
Exam Tips: Answering Questions on Flow Resources
Tip 1: Know Your Data Types Exam questions often test whether you understand which resource type is appropriate. Record variables store one record. Record Collections store multiple records. A Get Records element set to return "All Records" requires a Record Collection.
Tip 2: Understand Input/Output Settings Questions may ask how to pass data into or out of a Flow. Remember that variables must be explicitly configured for input or output availability. This setting determines whether subflows or calling processes can interact with the variable.
Tip 3: Distinguish Between Resource Types Know the difference between Constants (fixed, unchangeable values) and Variables (can be modified). Formulas recalculate dynamically, while Variables retain their assigned value until changed.
Tip 4: Text Templates vs Variables Text Templates support rich text formatting and merge fields, making them ideal for email content. Regular Text Variables are better for simple string storage and manipulation.
Tip 5: Choice Resource Questions When questions mention dynamic picklists or presenting record options to users, think of Record Choice Sets or Picklist Choice Sets. Individual Choice resources are for static, predefined options.
Tip 6: Read Scenarios Carefully Exam scenarios often hint at the correct resource type. Words like "multiple records" suggest collections. "User selection" suggests choice resources. "Fixed value across the organization" suggests constants.
Tip 7: Remember Scope Resources exist only during Flow execution unless the Flow is paused (in which case certain variables persist). Global Variables like $User or $Record provide system information and are available throughout the Flow.
