Follow / Support Buttons

Good afternoon!

I have 2 questions for anyone who can help out!

1.) Is there a way to create a follow button? I currently am grabbing if they are already following a campaign and want to display an option for them to follow to go along side becoming a patron, but couldn’t find anything in the API for it

2.) Was looking at the embed “become a patron” button that’s generated through the dashboard, but i wanted to get a tad more granular with it. Is it possible to generate a button directly to the pledge for the different tiers? For example, i have 2 different tiers, a basic support level, and a $5 tier for those who want to unlock features on my website. I was hoping to display both of these buttons on the site, with descriptions of both, that way they dont have to go external from the site.

any ideas??
