Hello experts,
I want to run an experiment in which I need to direct every single participant to a different external website. Therefore, I would like to show participant #1 Link #1, participant #2 Link #2 and so on.
Is there a way to count how many participants have started the survey? I read that it could be possible to set up a quota and count how many participants have already finished the survey. However, if participant #1 and #2 start at the same time, then they'd both unfortunately see Link #1.
I also thought about just creating one condition for every possible participant. Let's say I predict 100 participants will participate, that'd mean 100 conditions, so 100 unique blocks. However, I could just randomize them into the conditions, meaning that two participants might end up in the same condition. Or is there a way to direct participants to a block and then prevent any other participant to ever be directed to that block again?
I want to direct every new participant to a unique/different block. Is this possible?

Use embedded data for your external url and pipe it as needed. Then you can have a survey flow randomizer with 100 embedded data blocks that assign the value of the url to 100 different values. Set the randomizer to display 1 of 100 and check "Evenly present"

Thank you for your quick answer!
Unfortunately I ran into some other issues and it now seems unlikely that I can go this route, but if I do I'll do as you suggested.
I noticed that you commented on a question regarding tableau and POST request, if you'd have some idea on the issue I am facing now, I would much appreciate your feedback: https://www.qualtrics.com/community/discussion/12042/automatically-login-to-tableau-without-disclosing-user-name-and-password-to-my-participants/p1?new=1
https://www.qualtrics.com/community/discussion/comment/29612#Comment_29612I tried it out, but doesn't my original problem persist?
I created a randomizer and added 100 embedded data elements. Each element has the same field I called"URL" but with different values. For example, the first element has one field "URL" = "Link1", the second element "URL" = "Link2" etc..
Setting the randomizer to display 1 of 100 and checking "Evenly present" only roughly randomizes. It doesn't make sure that each participant gets a unique Link. By chance, participant 1 and 2 could both be assigned "Link1".

This web service will assign unique link to 100 respondents.

I have no experience with webservices, how complex would you rate setting up such a web service if you are a complete beginner? How much time needs to be invested? (I just have some basic java and R programming skills, and very very basic HTML skills).
