Why Define Variables?

Defining variables helps:

• Enable autocomplete when using variables in actions
• Validate incoming data

Webhook URL

After saving, you'll receive a unique webhook URL:

https://aismarttalk.tech/api/webhook/{your-unique-id}

Copy this URL to your external system.

Available Variables

All data sent to the webhook is available as variables:

Variable	Description
{{webhook.variableName}}	Any defined variable
{{webhook.body}}	Full request body (JSON)
