# On Attribute Changed

<div data-with-frame="true"><figure><img src="/files/KsalLduKc8hi8Fe94VIm" alt=""><figcaption></figcaption></figure></div>

**On Attribute Changed** is a bot trigger that activates when a customer attribute is updated in DoubleTick.

Attributes are stored customer details that help you track progress and segment leads, such as:

* Lead stage
* Customer type
* Interested product
* Location
* Visit scheduled (Yes/No)

Whenever the value of an attribute is set, updated, or removed, this trigger can automatically start a bot journey.

***

### Where to Use This Trigger

Use this trigger when your automation depends on customer status or lifecycle movement.

It is especially useful for:

* Lead funnel automation
* Sales stage follow-ups
* Personalized messaging based on customer actions
* CRM-style workflows inside DoubleTick

***

### How This Trigger Works

When you select **On Attribute Changed**, DoubleTick gives you a dropdown to choose:

1. **Which attribute you want to track**\
   Example: Lead Stage
2. **When the bot should run**, based on three trigger conditions:

***

#### Option 1: On Set First Time

This runs only when the attribute is being assigned for the very first time.

Use this when you want automation only at the initial update.

Example:\
Lead Stage is set to “Interested” for the first time → Bot starts welcome journey.

***

#### Option 2: On Changed Any Time

This runs whenever the attribute value changes from one value to another, at any point.

Use this when you want automation at every stage movement.

Example:\
Lead Stage changes from “Interested” → “Converted” → Bot sends onboarding steps.

***

#### Option 3: On Removed

This runs when the attribute value is removed or cleared.

This is useful for attributes that work like Yes/No flags.

Example:\
Visit Scheduled = Yes is removed → Bot sends a follow-up asking to reschedule.

***

### How to Use It in Bot Studio

1. Open **Bot Studio** and create a new journey
2. Select trigger: **On Attribute Changed**
3. Choose the attribute from the dropdown (example: Lead Stage)
4. Select when the trigger should run:
   * On Set First Time
   * On Changed Any Time
   * On Removed
5. Build the automation steps and publish the journey

***

### Key Capabilities

* Supports automation based on customer lifecycle updates
* Helps build stage-based and personalized journeys
* Works well for CRM-style workflows
* Gives control over first-time, repeated, or removed changes

***

### Example Use Case

A sales team uses Lead Stage as an attribute.

* When Lead Stage is set to “Interested” (first time), the bot sends product details
* When it changes to “Converted”, the bot sends onboarding steps
* If a scheduled visit value is removed, the bot sends a rescheduling reminder
