Return HTTP 200

Hi guys, I’m trying to create a bot in Slack and I intend to add events, but to add events I need to put a url to receive a challenge and respond to Slack this challenge with HTTP 200.

I thought about using Return data from API but I can’t finish the flow because I need to generate the endpoint, put it in Slack, then Slack will send me the challenge but I need to instantly respond to the challenge through Slack, and that doesn’t happen because I can only handle the response of the challenge, when it arrives at the Bubble and then Slack returns an error

If anyone knows of any alternative or thing I can do to overcome this barrier. Thanks!
