While trying to implement LS to WP I'm facing some difficulties. By now i read several threads and other pages as well as the manual.

Goal would be to generate a token each time a WP user clicks the survey Link on a WP-Page and at the end of the survey pass the token to WP.

With another link in WP the participant should be able to head to the survey-URL to edit his answers. So the token should be passed from WP to LS and automatically filled in into the token field.

First struggle is auto generate of the token. Or is there any way to edit the survey without tokens? for example with the surveyID?

Any best practices how to do so?

Draft of the approach

I think this will help you:
