Rules for Signup is not invoked when I use REST API(endpoint for signup)

[jesse2]

I found another thread with a similar issue (thread is closed)

Is it correct that rules only fire on login, and not a signup?

I cant seem to set any app or user metadata when signing up a user, and looking at the logs the rules is not firing at all. Only when I call the webauth.client.login will the rules fire, and not on webauth.signup.

@jmangelo Are Pre-User-Registration hooks the only way to run something after both a Signup from the Custom Signup API, and signup through the Universal Login Lock web form?

We are only using password type token retrieval, not Auth Code type, like the Universal Login form uses.
