# Message from CTWA

Message from CTWA is a universal trigger that activates whenever a WhatsApp conversation begins from any Click-to-WhatsApp ad, even if the Facebook ad account is not connected to DoubleTick.

Unlike Lead from CTWA, this trigger does not depend on campaign or ad data. It simply detects that the message came from a CTWA entry point.<br>

#### Where to Use This Trigger

Use Message from CTWA when:

* Ads are being run by an external agency
* You do not have access to connect the Facebook ad account
* You want a single bot journey for all CTWA leads without attribution

It is commonly used as a fallback trigger to ensure no ad lead is missed.

#### How to Use It in Bot Studio

1. Open Bot Studio and create a new journey
2. Select trigger Message from CTWA
3. Add your first response automation, such as welcome or qualification questions
4. Publish the journey

After publishing, any customer who messages through a CTWA ad will automatically enter the bot flow.

#### Key Capabilities

* Works even without Facebook integration
* Covers all CTWA ads universally
* Useful when attribution is not available

#### Example Use Case

An agency runs ads using your WhatsApp number.\
Even though the campaign is not visible in DoubleTick, the bot still starts and replies instantly.
