Fire a webhook when a customer clicks a specific button in a flow built following How to Create a Keyword-Based WhatsApp Chatbot — track button interactions, trigger an external action, or sync data the moment a customer makes a choice.
Configure Button panel with the Send data to Webhook URL field boxed, below Assign Conversation to a group/user and above Send data to Google Sheets and Send data to Google Calendar
1

Open a button's settings

In your bot flow, click a Button component (inside an Interactive Message) to open Configure Button.
2

Find Send data to Webhook URL

Scroll down past Assign Conversation to a group/user.
3

Enter the webhook URL

Paste your webhook endpoint URL. Every time a customer taps this specific button, ChatSyncs POSTs the subscriber’s data to that URL.

Save Changes

Click Save Changes.
Each button in a flow has its own Send data to Webhook URL field, so different buttons can trigger different external systems: Example: In a university admissions bot, the Admissions button sends data to an admissions CRM webhook, while a separate Courses button sends data to a course-catalog webhook — each fires independently based on which button the customer actually taps.
The same panel also has Send data to Google Sheets and Send data to Google Calendar — you’re not limited to a webhook alone.
