Hey guys! I'm trying to use LS to collect data for a survey. My question is about a functionality of the platform. After completing my questionnaire, I need each participant to receive an automatically generated link with three more accesses. This link must be sent to three new participants. Successively, each new participant receives a new automatically generated link with three more accesses to the questionnaire.

Ideally I need to identify the relationship between ID and token, as shown in the image
 

Only a plugin can do this in my opinion

extensions.sondages.pro/about/contact

Maybe redirect to a PHP page that uses the API add_participants() and invite_participants() methods.

An old example - forums.limesurvey.org/forum/can-i-do-thi...rvey?start=15#171537

In Survey 1: generate a random code. Use this random code in an email that you send to the respondent, showing a URL that they can use to invite three other people.
research.respondage.com/index.php/887227?newtest=Y&lang=en (this works and the URL for survey 2 will be sent to your email)

Example of URL for survey 2
research.respondage.com/index.php/353658...Y&lang=en&pin=QAZWSX
