I am looking for a way to enable "external" users who are not actual Avo app users in order to digitially execute (sign) a contract within Avo. 

App users would send an email to external/non-app users containing a URL they can visit within Avo to execute (sign) an agreement. 

These "external" users would only need access to one particular show page where they could click an action button, enter their name in the modal and consent to some terms.

 I am seeking the simplest solution. We're using devise for authentication. Perhaps setting up one devise user account any external/non-app user could use to authenticate with? Is it possible to give access to unauthenticated users?

Thanks in advance!

I'm unavailable to test this out at the moment, but I think you coudl do something at the route level

We celebrate Easter this weekend and I'll be on and off from work, but I'll try to work something out

so, it's doable. if it isn't, setting up a user with a special role that can access only some parts of Avo, is the next best thing

Makes sense! I'll investigate further. 

Thank you for the prompt reply and Happy Easter!
