~~For example:

js
window.botpressWebChat.sendPayload({type:'text', text:"WS1"})

... where

WS1

is an internal code for your website. Then in the start node of your bot you can check if the incoming message matches one of the internal codes you define. Not the most elegant solution, but should work for now while this is not available as an official feature.~~ Please see my revised answer below for a better implementation of this solution: https://discord.com/channels/1108396290624213082/1133770315873398794/1136041731280863434

ok so Trigger is in Beta. https://discord.com/channels/1108396290624213082/1121833577659768893 I requested an access.

BTW, as a revision to my original answer, it will be better to use

.sendEvent()

as it won't appear as if the user sent a message. So, from the page the webchat is embedded on, you can call:

js
window.botpressWebChat.sendEvent({ type:'trigger', websiteCode:"WS1" })

And then in your bot just add an Event > Message from channel card into your workflow, then in that card select the "Trigger" option from the "Trigger On" dropdown, and then connect a new node to that trigger and you can now use the

event.payload.websiteCode

variable to know which the code of the website your bot was opened on, so you could add an Execute Code card there with this code:

js
session.websiteCode = event.payload.payload.websiteCode

And then anywhere in your bot you can simple use the

session.websiteCode

variable to know which website your bot is running on 🚀
