Configuration page text Input for panel

Ive done some searching, but have came up empty handed. i assume my google-fu needs some working. But here is what i have going on. I have created a panel with html, within the panel i need a user inputted text. Its basically for a “enter (blah) at checkout”. Blah being what i need the streamer to be able to enter. I assumed this would be done from the configuration page? If this even possible to do? I appreciate any help or input.

Yes

Edit: not sure what else to add here.

You can provide the broadcaster input field on the broadcaster config page or the broadcaster’s dashboard page.

And then from there it’s up to you where you want to store and recall that information from. You can shove it in your EBS or shove it into the Twitch Extensions Config service
