AgapeList Congratulations on getting the Make.com integration working! That's definitely something to take a bow for.
To answer your question: I took a look at the core files (specifically RegisterUserHandler.php), and unfortunately, there is no native flag like forcePasswordChange built into the Flarum API when creating a new user.
flarum/frameworkblob/main/framework/core/src/User/Command/RegisterUserHandler.php
However, there is a very practical workaround you can do entirely within Make.com by adding just one more step to your scenario:
Trigger the Forgot Password Flow:
- Continue creating the user in your first Make.com module, but generate a very strong, random password for them.
- Immediately after that module, add another HTTP request module in Make.com that sends a
POST request to Flarum's /api/forgot endpoint, passing the email address of the user you just created.
This will automatically trigger a password reset email. That way, the user's very first step to access the forum will be clicking that link and setting a password of their own choosing.
Hope this helps!
