I would like a .PHP program (external to LimeSurvey) to add a new survey participant to the survey participant table, generate an access code for the new participant, and then trigger the sending of an invitation to the participant by LimeSurvey. Is this possible?

Hi,
if there is a php program I'd recommend to do everything within this program.
1. Create the access code (you could use
"function generateRandomString($length,$cryptographicallyStrong=true)"
in "CSecurityManager.php")

2. Create your invitation mail and send out with something like "phpmailer".

3. Insert the participant into the participant table with the correct datetime of invitation.

Here is an example of how to add and invite a participant using the API in PHP.

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

I was blind, as usual
I didn't see the API function

Invite participants in a survey (RPC function)

invite_participants(string $sSessionKey,integer $iSurveyID,array $aTokenIds = null,boolean $bEmail = true): array

Returns array of results of sending
