Is it possible to integrate with Etsy OAuth?

Since I don’t have the preconfigured option for Etsy connections in the social tab, I was thinking if there is an easy way to implement with Auth0 this connection to Etsy OAuth through a serverless Angular 4 web app?

According to Etsy documentation they provide an OAuth1 implementation.

The Etsy API uses OAuth 1.0 to give developers access…

This means you should be able to follow their documentation and Auth0 on how to add a generic OAuth1 authorization server implementation to Auth0 so that you could then use it as the default social connections. More specifically, you should follow:
