Hi Im new in Twitch streaming but i watched twitch for long time and I did my first live with OBS today, it had lag but i will correct that mistake in OBS configuration. My problem is that i want to put buttons in my streamings, is it possible to put a YouTube button? Or a donation button and all that, so how can i put them?

This forum is for 3rd party developers. There’s currently no way to put interactive buttons over the stream player on Twitch if that’s your intentions. Use panels instead. Here’s information on streaming, how to edit panels, and markdown basics to get fancy.
