You can send custom events from your website to Webchat. This is useful if you want your bot to transition to a certain Node or Workflow when something happens on your website.
You will need:
  • A website with an embedded bot
  • Familiarity with JavaScript

Send an event to Webchat

First, setup an event to send Webchat from your website’s source code:
index.js
const customPayload = {
    "test": "test"
}

await window.botpress.sendEvent(customPayload)
customPayload can be any JSON object.

Add a custom trigger

Next, add a custom trigger Node in Studio:
  1. In your Workflow, right-click and select Trigger, then Custom Trigger:
Custom Trigger
  1. In the Event Filter field, enter {{ event.payload }}. This will capture the most recent event you send.
  2. Select Test, then Show last received events. This will display any events you’ve send from your website.
  3. If you’ve already sent your event, it should show up here. Select Add as Test, then Save.
The trigger Node won’t work until you’ve succesfully tested it.

Test your trigger

Now, you can test your trigger Node:
  1. Add a transition from the trigger Node to another Node. For example:
Test Trigger Node
  1. Select the Play button to execute the trigger Node in the Emulator.
Done! Now you can send custom events to Webchat.
