Using Channel Points to trigger an URL

Sure.

All we can help you with on this forum is how to obtain a channel points redemtption message.

Which can be done via EventSub (either Webhooks of Websockets transports)

That’ll give you a real time message of a redmeption occuring then it’s up to you to then call the URL you mention

Once you have that working, you can do whatever you want to trigger whatever you want.
