How can we call auth0 API in Jekyll
Jekyll is a static site generator, that is, it will only render plain html files. If you’re looking to build a website that calls an API you should be looking into generating a single page application with jekyll (where the javascript will call the API) or using something like Rails or Sinatra.
Hope that helps!
Depending on your requirements, Netlify has a permissions feature you might want to check out (link), and a quick Google search tells us auth0 has Webtask.io (link) that appears to allow what you seek.
Give us an idea of your basic requirements and I’m sure the community here will have a few other ideas.
