Three-Legged Oauth

  • Last updated on

Ruby apps can use the omniauth-sign-now[1] library to simplify this process.

Step 1: Redirect user to SignNow auth page; provide a redirect uri for the user to return to once they have authorized your application at https://www.signnow.com/[2].


example: https://eval.signnow.com/proxy/index.php/authorize?client_id=123412341234abcacbacba&response_type=code&redirect_uri=http://my.redirect.uri

Step 2: After the user has authorized your application at signnow.com, they will be redirected to the redirect uri that you provided; a code query parameter will be provided. 


Step 3: Use the provided code parameter to get an access token from SignNow.

curl https://api-eval.signnow.com/oauth2/token --header "Authorization: Basic {BASIC TOKEN}" --data 'grant_type=authorization_code&code={CODE}'
