I am currently in the process of creating a Webhook and the app I am accessing uses immediate confirmation which requires me to return a 200 code to confirm I want to receive Webhook notifications. How do i go about returning this 200 code? The app I am using sent a POST request to me with a random secret included in the header. It then wants me to return this secret as a header in a 200 code response.
I do not understand how I return this 200 response code, do I need to use a HTTP request?
Any help would be much appreciated!
