Constant

Constants in JENTIS

Constants are a special type of variable in JENTIS used to define fixed values that remain consistent across your account and environment. They are ideal for values that do not change dynamically during a session, event, or user interaction.

---

Purpose

Use constants to:

• Store global configuration values

• Maintain consistent settings across containers and environments

• Avoid hardcoding static values inside variables or tags

Common use cases include:

• Currency codes (e.g., EUR, USD, CZK)

• Language settings

• Default country or market

• Global flags (e.g., versioning, feature toggles)

---

Characteristics

Attribute	Description
Scope	Account- and environment-wide
Definition Location	Defined once in the JENTIS Tag Manager (JTM)
Usage	Can be used in any variable, trigger, tag, or transformation
Behavior	Static – the value does not change unless manually updated in the JTM

---

Example: Currency Configuration

	Environment: Live	Environment: Stage
Container #1	EUR	EUR
Container #2	CZK	CZK

In this example, each container uses a constant called currency, and its value is set per environment, remaining consistent throughout.

---

Benefits

• Centralized management – change the value once, and it updates everywhere

• Improved maintainability – no more hardcoded values in multiple places

• Environment awareness – different values per stage/live environment if needed

• Cleaner variable logic – keep static config separate from runtime logic

---

How to Use

1. Define the constant in the JENTIS Tag Manager → Tool or Account Settings

2. Use the constant by referencing it in any logic or configuration (e.g., via this.accountvars["currency"])

3. Maintain different values per container or environment if necessary

---

Summary

Constants are essential for storing and reusing values that stay the same across your JENTIS setup. They make your tracking logic cleaner, more manageable, and consistent, especially when working across multiple containers or environments.
