[@aswin123ify]

hi Sandesh, thanks for your informative content. can you please share more information on invoking REST api from custom activity and presenting data inside the activity UI, incase api needs credentials like api keys, api secrets how would you be able to store them securely and embed in custom activity fetch request ? also what will be the practical usage of having endpoints defined under /save, /validate, /publish and /stop

bro i want to create a custom journey activity to send data source fields like name, email etc to an external api. I am trying it so hard and even read the documentation. Can you suggest me any important consideration while building this application.
