How to determine the calling application within PostUserRegistration

[yoshida_seiichi]

Hello,

In our Auth0 tenant, we have multiple applications: A, B, and C. I need to implement specific processing for registrations coming from Application A in the PostUserRegistration action. How can I determine within the PostUserRegistration action that the registration came from Application A?

Thank you.

Hey there @yoshida_seiichi!

Apologize for the delay here - There’s no way to determine the client_id in a post user registration action as there there is no event.client object. Instead you would need to look into utilizing a post login action similar to what’s described here:

Access client_id in a post-user-registration Action

Hi @christien.guy, Welcome to the Auth0 Community! It looks like the post user registration Actions doesn’t include the event.client property, unlike the post login action. The best way to workaround this would be to use a post login action. You can set a flag in the user’s metadata to indicate they have been added to your CRM after a successful update, or set it to run based on the event.stats.logins_count. Does that make sense?

Hello.
Thanks for the helpful topic.
It would have been nice if the client_id could have been referenced, but alas!
We will look into using metadata.

Thank you so much.
